What are Veolia Water Technologies’ goals for the next two years?

The past few years have presented many challenges for Veolia Water Technologies, with a market that has been rapidly changing, and we ourselves also need to change and adapt.

As Veolia Water Technologies, our wealth is obviously made of our technologies and we will keep capitalizing on them, improving them and developing new ones. We want to simplify our portfolio of technologies, making them available faster and at a more competitive price point. We are also looking into digitalization of some of our standard equipment.

Another key point for us is to further develop our bundled services, including our mobile water services, traceability for specific regulations, digital functions, etc. There is a strong demand for these types of services and we want to better capitalize on that through our local teams.

We are still relying on our strong design and engineering capabilities to secure some big design-and-build contracts, for instance for desalination plants in the Middle East,

municipal water and wastewater treatment plants in Europe, Africa and Asia, and industrial projects in North and South America.

What are some factors you see impacting the water technology market in the coming years?

Over the next twenty years, the middle classes will grow from one to three billion people. By 2050, it is expected that 70% of the world population will live in an urban environment. This could mean up to double the amount of people living in towns and cities around the world, straining local resources and concentrating pollution and waste.

Climate change is causing a more frequent number of natural disasters that are taking an ever heavier human and material toll. 2015 set a series of record temperatures: on a global scale, according to recent reports from NASA and the UN, the average temperatures in 2015 have been the highest ever recorded on the earth’s surface.

These factors will cause unprecedented pressure on water sources and other natural resources. Successfully facing these challenges will require innovations and a new way of thinking, working and consuming.

We are being forced to call traditional concepts into question.

The current mobilization of all stakeholders on the crucial issue of climate change is unprecedented. This context is a great opportunity to invent together a more responsible and less carbon-intensive economy, advocating for a new use of resources. The fight against climate change can be a source of value creation.

We hear a lot about the circular economy; why is it so important to include water in it, and why has it not really been considered as a vital part in the past?

As I said, demand for raw materials, including water, is exploding as a result of demographic growth, rising living standards and climate change. As we are all aware, we cannot endlessly draw on the natural environment – a number of shortages are already making themselves felt and the growth model based on linear consumption (extract-use-throw away) has reached its limits.

Scarcity of raw materials, scarcity of water, carbon footprint: these are huge challenges facing our world today. The management of environmental issues is becoming increasingly important and complex

in both rapidly developing and developed countries.

Access to water is a key factor in the growth of entire economies, cities and many different industries. Today, on a worldwide scale, barely 2% of wastewater is reused: that remaining 98% of wastewater represents a valuable and readily available resource that we must tap into. Wastewater also has the tremendous advantage of being available where water is needed.

The whole point of the circular economy is to give back value to things that had lost their value which of course applies to water and wastewater. When scarcity strikes, the circular economy allows economic players not only to secure their supplies, but also to reduce their expenditure and create additional revenue. This approach does not arise exclusively from environmental concerns; for the regions, it is a factor in their development and for businesses, it is a source of competitiveness and wealth.

How can water technologies be adapted to address the issue of climate change?

We are in a period of witnessing the development of renewable energies, but some of them, such as solar energy or wind power, have one serious flaw: they only produce electricity intermittently. On the other hand, heat recovered from sewer systems delivers a permanent and continuous source of energy. This is why energy service providers are paying more and more attention to this alternative.

Methane is 80 times more damaging to the climate than CO2. Calculated over a period of 20 years, methane represents 40% of greenhouse gas emissions. However, methane can be captured and used to produce

heat and electricity, transforming this pollutant gas into green energy. Wastewater treatment activities can produce a lot of methane which can be repurposed to produce renewable energy through biogas, quickly producing positive effects.

Obviously, sludge offers a lot of potential as far as energy production goes and it is viewed more and more as a valuable resource to capitalize on rather than a waste that needs to be discarded. The latest technologies using thermal hydrolysis, for instance, concentrate the matter to be treated, reducing the volume to be heated. The end result is 20 to 40% more biogas produced than by using conventional digestion, and up to 50% more capacity for existing digesters.

We are seeing more and more self-sufficient wastewater treatment plants starting-up all around the world. With the optimization of technologies and associated services in the years to come, this trend will only accelerate and hopefully become the new normal.

Can you give some examples of corporations and collectivities which are changing the way they approach water and wastewater treatment?

Improving water management in industrial processes has become one of the major aims of a growing number of company heads. They are gradually becoming aware of the

risks of an industrial failure linked to blue gold that could seriously impact their company’s operating results.

Nestlé, for instance, has reduced its water consumption globally by one third during the past 10 years and by 50% at its plants in Mexico, even while global production has increased. Thanks to a Veolia process, the company’s Lagos de Moreno dairy plant became the first of Nestlé’s Zero Water plants, which means it no longer extracts any water from natural resources in this region of Mexico which suffers from water stress.

Antero Resources, one of the top ten producers of natural gas in the United States, is another company that is proactively addressing water consumption by using Veolia patented technologies to build a $275-million centralized water treatment facility to treat and recycle the produced water from its shale oil and gas operations. This will enable Antero to realize substantial savings while reducing its environmental footprint.

Municipalities all around the world are also taking steps to increase their resilience. Copenhagen, for instance, has installed an electronic system to make better use of existing canals and infrastructure to reduce flooding in case of heavy rain, which has reduced the amount of flooding by 80 percent.

Durban, one of the driest cities in South Africa, is managing the supply of drinking water to ensure priority is given to the city’s residents. The Durban Water Recycling plant supplies the city's industries with recycled, cost-effective water of sufficient quality to be used in manufacturing processes. 98% of the city's wastewater is now recycled and 40,000 cubic meters of additional drinking water are supplied daily to the people of Durban. �

“The fight against climate change can be a source of value creation.”

Veolia Water Technologies creates and implements tailored or standardized water and wastewater treatment solutions for industrial and municipal clients. With our clients, we develop a business strategy to optimize water and wastewater treatment facilities and to provide the following benefits:

� Reduced costs and enhanced savings� Recovering co-products and reducing waste� Partnering for continuous improvement� Operation excellence� Direct access to proven technology and technical innovation� Dedicated and specialist resources� Excellence in health, safety and environmental management

We also provide services and solutions (treatment chemicals, mobile water services, etc.) to maintain and upgrade water and wastewater treatment facilities and systems.

Creating water solutions


Veolia Water Technologies has strengthened its “Anytime, Anywhere” water treatment capabilities by adding 600 and 900 gallon per minute (GPM) Reverse Osmosis (RO) units to its extensive mobile water services fleet.

The new units join a fleet of portable trailers and containerized water and wastewater treatment solutions for temporary, emergency and long-term water treatment applications. By combining various technologies, Hydrex™ chemistries and field services, customers have the flexibility to choose a stand-alone mobile equipment rental or complete, integrated service. Current units in the US fleet are Reverse Osmosis, Actiflo® TURBO Clarification, Filtration, Softening and Demineralization.

Potential applications served include physical and chemical separation for suspended solids, turbidity, hardness and metals; membrane separation and demineralization

for TDS (total dissolved solids) reduction, specialty ion exchange and heavy metals removal.

According to Michael Reyes, Veolia’s Mobile Water Services National Sales Manager, the breadth of water treatment capabilities provides solutions for a variety of customer water needs including: short and long-term for planned maintenance and retrofits rental options for peak or seasonal demand supplement existing supplies delivering permanent solutions without requiring design/build construction emergency situations.

Reyes points to case study of a nuclear plant as an example of a targeted solution for a short-term, but highly problematic challenge of a local river threatening to contaminate the seal water main reactor clear well.

“In this instance we deployed our mobile Actiflo TURBO Clarifier system to treat 250 GPM of excess river water

followed by multi-media filtration. This was an ideal solution because it allowed the client to rent the system on a short-term basis until the flood was contained,” he explained.

The new mobile reverse osmosis rentals can operate in either single or double pass orientation, with flows ranging from 100 GPM up to 600 GPM. The systems are fully automated and come complete with CIP (clean-in-place) capabilities, to meet water purity requirements with a minimal amount of manpower.

The 900 GPM High Recovery RO technology relies upon a patented design and operating function to provide higher recoveries and higher permeate flux rates than traditional RO technology. Through a closed circuit recycling of the RO feedwater, the membranes are less susceptible to fouling by water impurities and are able to capture up to 95% as permeate, reducing needed pretreatment capacities and saving valuable water. �

Mobile water treatment anytime, anywhereFast Mobile Water Services


The power of reclaimed waterThe population continues to grow, demanding more output from fewer resources. This strain is felt acutely in the power industry. New plants are built to accommodate the growing population’s power needs, requiring more water than ever for power generation and cooling. As freshwater resources continue to dwindle, more plants are turning to reclaimed water.

To get a handle on how and why the power industry takes advantage of reclaimed water, some of our experts shed light on the state of the water-energy nexus, the advantages of utilizing reclaimed water, and the unique treatment issues it poses.

What is the state of water risks faced by the power industry?

The interplay between water and energy is known as the “water-energy nexus.” This describes the relationship between water used for

energy production and the energy that is required to extract, purify, treat, and dispose of that water. This nexus continues to be strained as population growth exerts more demand on both water and energy and as drought conditions emerge in unexpected places around the world. Feeding this growing population will further strain the freshwater supply as irrigation is the number one consumer of water.

The risk of freshwater shortage is real and the effect upon profitability and company stock prices is real as well. Bloomberg reported last year that when the science minister of India reported less than normal rainfall, there was a drop in the nation’s equities of $23 billion in a two-day period. Last year, the World Economic Forum listed water crises as the number one risk facing the world.

Because power generation uses water more than any other industry,

that is a primary area where water conservation needs to take place.

What are some ways the power industry can reduce water use?

An easy one is to use water more efficiently. You can increase the cycles in the cooling tower; we have some clients who do so up to 20 times. You can find a non-freshwater source for cooling, which is the biggest user of water in the power plant. You can use treated sewage or industrial wastewater. You can recycle and reuse your own wastewater. You can improve the efficiency of the power unit so you’re producing more megawatts per gallon of water used, which also adds to both sustainability and profitability.

Treated municipal wastewater, or reclaimed water, is one of the most available sources for power plants and can be an effective tool for reducing freshwater use.


What are the advantages of using reclaimed water for cooling?

For one, the use of sewage effluent for cooling is proven and safe. In the U.S. it began in the 1970s. It’s estimated that today more than 70 of the country’s power sites are using treated, reclaimed water — and not just in dry areas.

Sewage is a virtually risk-free source. It has consistent quality and temperature compared to surface waters. Because secondary effluent is relatively consistent in quality, the treatment process, design, and operation become easier. Also, the cooling tower blowdown may be able to be returned to the municipality, eliminating one of the waste streams needing treatment at the power plant.

What regulatory considerations affect power plant cooling?

There are several sets of regulatory requirements that govern the use of reclaimed water for cooling.

Federally, the Clean Water Act (CWA) requires that all discharges of pollutants to surface waters are authorized by a permit issued under the National Pollutant Discharge Elimination System (NPDES) program. The U.S. EPA implements the NPDES program and has the power to

authorize states to issue permits and administer the program. NPDES permits contain discharge limits determined by the treatment technology that the EPA believes is available and affordable, as well as by the states’ water quality standards and available dilution in the receiving water body.

State rules vary, usually taking into account the likely degree of public exposure to reclaimed water. Where the exposure is high, reclaimed water must be highly treated. States usually establish limits on fecal or total coliform bacteria and may require wastewater be filtered before it can be reused as reclaimed water. They also usually have turbidity standards.

What are some challenges that the quality of reclaimed water poses

for operational use?

Facilities that utilize reclaimed water have to figure out how clean it must be to satisfy their individual operational requirements. Reclaimed water’s chemical elements can cause problems like mineral scaling, corrosion and stress-cracking, and biofouling.

Interestingly, these problems are increased in closed-cycle cooling systems when water evaporates and leaves behind higher concentrations of constituents. To control the water quality, power plant operators can remove some of the concentrated, recirculating water. They can adjust the flow volumes and makeup. They can treat the incoming reclaimed water before it is added to the recirculating system.

Can you share any case studies that relate to the water quality necessary for use in cooling towers?

In 2012, Veolia advised a client that it would experience problems if it continued to send water at its existing quality to its towers. We found that the use of disc filters would be an effective method to treat their sewage plant effluent for cooling tower makeup and Veolia was contracted to do so.

In another case, the West Deptford Energy Station in New Jersey was using treated effluent diverted from a local sewage treatment plant for its non-contact cooling tower makeup, boiler feedwater, and plant service water. Veolia was contracted to assist in the supply of water treatment technologies to support the station’s environmentally-friendly and sustainable energy operation. We furnished it with a biological aerated filter (BAF) and disc filter system which allowed effluent from the plant to be reused in the cooling tower, with a treatment capacity of 7.35 MGD. The BAF greatly reduced the ammonia level in the sewage, thereby saving the power company a large amount of chemical addition. The owner added ultrafiltration ahead of the membrane based demineralizer system, enabling the use of treated reclaim water as a source of boiler feedwater.

What do you think the future is for reclaimed water and power plant cooling?

As freshwater supplies dwindle and demand grows, the power industry has come to realize that reclaimed water can be a very valuable source. As the power industry continues to expand globally, it will call upon reclaimed water to meet its needs for cooling and potentially other process applications. �

Fighting resource scarcity, one battle at a time

Interview with Klaus Andersen, CEO of Veolia Water Technologies in the Americas

Big problems call for big ambitions. With the planet confronted by global warming, world hunger, exploding urbanization and resource scarcity, Veolia’s newly adopted mission description, “Resourcing the World,” seems appropriately scaled.

The global tagline reflects the company’s determination to help break society’s resource consumption dependency and switch to a sustainable use-and-recover approach. The performance-improving solutions Veolia delivers to its customers provide access to needed resources while at the same time preserving and replenishing them.

Not that the company plans to respond to all of the planet’s challenges all at once. “Rethinking our relationship with resources and creating new, more efficient, better balanced and more sustainable growth models is an ongoing commitment,” says Klaus Andersen, CEO of Veolia Water Technologies

in the Americas. “It’s a campaign we fight one battle at a time, project by project, delivering solutions that can then be leveraged throughout the world.”

On the front lines: water scarcityThe combination of resource stewardship with performance improvement is visible in Veolia’s ability to help fulfill the needs of industrial as well as municipal customers for one of the earth’s vital but increasingly stressed resources: water. The Organization for Economic Cooperation and Development estimates that 1.5 billion people today live in areas seriously affected by water scarcity with that number projected to increase to almost 4 billion by 2050, absent adoption of more sustainable practices.As water is increasingly a global environmental and humanitarian challenge, access and use of the resource is becoming a major issue for many industrial customers. Veolia’s ability to deliver sustainable solutions that protect water resources is a real competitiveness driver.This is a priority particularly evident in the dynamic energy area, as illustrated through some recently completed projects.

Enabling sustainable oilfield expansionIn the San Ardo Field in Monterey County, California, Chevron needed a solution for its water needs to

enable increased oil production. The 2,500-acre field is the 13th largest oil field in the state, with an estimated ultimate oil recovery of 530 million barrels. Chevron’s oil production had been declining in recent years, due to limited capacity for disposing of the produced water that comes to the surface as part of the oil and gas extraction process. The challenge for producing the remaining heavy oil was to remove the excess water from the reservoir, which can range from 10 to 20 times the oil production rate.

Working with Chevron, Veolia designed and built a new membrane-based water desalination facility to allow a portion of the produced water to be treated and discharged to a shallow fresh water aquifer (pictured left). The project, commissioned in October 2007, was the first produced water desalination facility in the world to use Veolia’s OPUS® technology, which has proven to be a reliable and robust process for successfully treating produced water for surface discharge. OPUS® combines high-rate chemical softening, with filtration, ion exchange and reverse osmosis.

The plant is designed to process 66,700 barrels per day of produced water with a recovery factor of 75%, translating into an effluent treated water rate of 50,000 barrels per day. The multiple-treatment process is



effective in removing contaminants to meet the requirements for beneficial reuse discharge to aquifer recharge basins via post-treatment constructed wetlands.

The implementation of the OPUS® water reclamation technology / desalination allowed Chevron to meet its water needs with recycled water and expand its current area of steam-enhanced production into idled, previously developed portions of the field.

A more recent development for oil & gas applications is OPUS(r) II, which streamlines pretreatment through the use of CeraMem(r) ceramic membranes to improve oil removal.

Helping to ensure clean oil sands developmentIn Alberta’s Athabasca region, Veolia is helping independent oil and gas exploration production company Devon Energy Corporation conserve water resources and reduce the footprint of producing oil from oil sands. Veolia’s Steam

Assisted Gravity Drainage (SAGD) is enabling Devon to produce up to 35,000 barrels per day of bitumen at its Jackfish 2 Project, where total recoverable reserves are estimated at over 300 million barrels.

Devon needed a solution that is robust, compact, easy to install and simple to maintain to separate oil and gas from water and other waste. Veolia’s response included the design, engineering, fabrication and supply of a full size AUTOFLOT® Model AHP280 Induced Gas Flotation (ISF) unit. The unit separates oil from produced water or other oily water streams. Hydrophobic particles attaches to the small gas bubbles added into a mixture of oil, fine solids and water. These particles float to the surface as a froth and are skimmed into a launder. The introduction of gas is performed by an eductor, which uses effluent as its motive fluid, provided by one of the two recirculation pumps located on a companion skid package.

With the use of Veolia’s proprietary filtering and separating technology, it is helping improve access to resources by Devon in recycling and reusing the water required in the SAGD process. Based upon the successful integration of the ISF on Jackfish 2, Devon also asked Veolia to provide a second ISF unit for its Jackfish 3 project.

Long-running commitment While projects such as these underline how technology solutions can help drive new behaviors, it’s not a new role for Veolia. For over 160 years, Veolia has been helping cities and industries worldwide manage, optimize and make the most of their water resources. ‘Resourcing the World’ simply captures this commitment and better communicates the company’s determination to be part of the solution to the natural resource challenges it faces -- a mission our company is obviously tackling with passion and enthusiasm... one battle at a time. �


Nestlé draws water from its milkIn the water-parched Mexican state of Jalisco, Nestlé’s success in implementing zero-water dairy production offers hope for improved stewardship of water in a country where the resource is under serious stress. A unique technology is being implemented – and recognized – worldwide.

In October 2014,as Nestlé inaugurated its new dairy plant in Lagos de Moreno, Mexico, the celebration was about more than just the facility’s production of Nido, one of the world’s leading infant formulas. It was also about achieving zero-water dairy production.

To achieve this feat and as part of its global commitment to preserve water resources, Nestlé entrusted Veolia, along with dairy technology firm GEA Filtration, with finding a solution to reduce water consumption at its plant in the water-stressed state of Jalisco. Increasing population growth over the past 60 years has decreased available groundwater throughout Mexico. The Lagos de Moreno plant – actually three side-by-side facilities, which also produce ice cream and cereals, in addition to Nido powdered milk – requires 1.6 million liters of water per day, roughly equivalent to the daily water consumption of 6,400 people.

Zeroing in on resource savingsIn 2013, Veolia added new technologies to treat the effluent from the GEA Filtration-built wastewater treatment plant so

water could be reused within the plant. The effluent is made up of “cow water,” the condensate recovered from evaporation of dairy products, and discharges from the “clean in place” sanitization of processing equipment. A polishing system featuring Veolia’s Aquantis membrane bioreactor treats the effluent to produce a filtrate virtually free of solids. A further reverse osmosis

treatment step retains dissolved solids and salts to drinking-water quality levels. The project, called “Cero Agua” (zero water) by Nestlé, enables the treated water to be reused for non-food production applications such as cooling, watering the gardens and cleaning, eliminating the plant’s need for external water resources.

Leading a global waveNestlé has reduced its water consumption globally by one third during the past 10 years and by 50% at its plants in Mexico, even while global production has increased. The Jalisco Cero Agua project is one of more than 370 initiatives Nestlé is undertaking in its factories around the world that are helping to conserve water. A world-first for the dairy products industry, the zero-water technology is now being rolled out by Nestlé at its other plants worldwide, starting with dairy factories in water-stressed areas of South Africa, Pakistan, India and China.

In 2015, Nestlé was recognized at the Global Water Summit in Athens with the Corporate Water Stewardship award for the Cero Agua project. “Twelve years ago, we were told that this couldn’t be done, due to cost implications, water quality issues, the technical complexity involved,” said Jim Knill, Nestlé’s head of dairy operations. “But we’ve shown that the technology works – now we want to apply it elsewhere.” �

“Nestlé has reduced its water consumption globally by one third during the past 10 years and by 50% at its plants in Mexico, even while global production has increased.”


The largest hybrid desalination plant in the worldThe most energy-efficient desalination solution

Fujairah 2 is the largest hybrid desalination plant in the world, with a capacity equivalent to 595,000 m3/day of potable water. The hybrid desalination plant is exceptional not only due to its size but also because it combines the two technologies, Multiple Effect Distillation (MED) and Reverse Osmosis (RO), to which is added a pretreatment Dissolved Air Flotation (DAF) system. This state-of-the-art combination has proven to be a solution which meets the requirement for a constant, high quality potable water output, despite vast seasonal variations in the power output as well as algae bloom periods.

The desalination plant is linked to a 2,000 MW power plant. The high drinking water demand in the UAE does not vary substantially with the seasons whereas the power demand does: during summer, the power demand is high due to the use of air-conditioning while it is

lower during the winter months. Therefore, an innovative hybrid solution including MED and RO was called for to best match the demands from a cost as well as a performance perspective. The hybrid design is the most energy-efficient solution for production of desalinated water today.

The MED system composes the first section of the desalination plant and is the largest system of the two. It includes 12 MED units that are driven using steam extracted from the two condensing steam turbines and from the exhaust of the back pressure steam turbine. This provides maximum output from the MED units during the summer.

The second part of the desalination plant is based on RO and is driven by power rather than steam hence it can be operated independently of steam output and be used during winter to maintain water output when power demand is low. �

SPIDFLOW™: A NEW GENERATION OF RAPID FLOTATION Red-tide events are often a problem in the region and as such, the leading-edge technical solution put in place at Fujairah 2 also features an innovative pretreatment solution upstream of the RO system: Veolia’s Spidflow™ Dissolved Air Flotation (DAF).

Clarification of water containing low density particles is a delicate step, especially during episodes of fast algae growth.

Spidflow specifically fits seawater desalination pretreatment as an upstream step of a reverse osmosis membrane treatment chain. It is especially efficient during red-tide algal bloom periods and provides unequalled water treatment efficiency by eliminating over 99% of algae. The efficiency was confirmed during strong algae blooms in February 2011 and March 2013, when Fujairah 2 was able to maintain its daily production capacity while other plants in the region were forced to shut down or greatly reduce their production.

Creating an environmentally sustainable waste/wastewater treatment system for Jack Link'sTHE CHALLENGE Jack Link's, a leading protein snack producer, was in need of a water treatment solution at its facility in Alpena, South Dakota. Jack Link’s previous wastewater treatment system consisted of a Dissolved Air Flotation (DAF) system for FOG (Fats, Oils, & Grease) and TSS reduction. Effluent from the system was discharged directly to the sewer system, and the city municipal treatment plant was becoming overloaded as a result of the facility’s production increases and high BOD loads.

THE SOLUTIONVeolia Water Technologies partnered with Jack Link’s to develop a process that would solve the facility’s high BOD discharge issue, while simultaneously creating biogas as a byproduct to reduce the plant’s energy costs.

Veolia’s treatment process utilizes Memthane® Anaerobic Membrane Bioreactor (AnMBR) technology combined with a Sulfothane™ Biogas Desulfurization System.

Memthane pairs anaerobic biological treatment with ultrafiltration (UF) membranes to create an industry-leading anaerobic membrane bioreactor system. The bioreactor converts the plant’s waste into a methane-rich biogas, while UF membranes create a high-quality effluent that is discharged into the municipal sewer system.

Biogas from the Memthane system is then treated by Veolia’s Sulfothane system. This treatment step removes sulfur compounds from the biogas, which are highly corrosive and can damage downstream equipment. The scrubbed biogas is then sent to a Combined Heat and Power (CHP) Generator to create electricity onsite and offset energy costs.

THE RESULTThe Memthane and Sulfothane systems have exceeded performance and client expectations. Final permeate discharge from the Memthane system averaged less than 100 ppm

BOD for greater than 98% BOD removal rates. Membrane operation during the first 24 months of operation was stable with flux rates ranging from 9 to 18 lmh.

The Sulfothane system was able to reduce the biogas’s H2S levels from 6,000-8,500 ppm to less than 10 ppm, which is well below the generator’s manufacturer specifications.

Due to sustained process stability and consistent high quality effluent, the city treatment plant operation has improved greatly.

ENERGY POSITIVE WASTE/WASTEWATER TREATMENT PLANT The system is not only energy efficient, it is energy positive when operating at full flow. At this time, the biogas byproduct produced in the anaerobic reactor generates more electricity than the system consumes. The result is a fast return on investment for the capital purchase. �


Memthane® & Sulfothane™A Perfect CombinationMemthane® AdvantagesMemthane is ideal for high-strength and high-solid waste streams from industries such as food processors, dairies, bio-ethanol producers, and many other food and beverage production facilities.

The effluent is free of suspended solids to facilitate recovery of nutrients for fertilizer production and/or water recycling to the plant. The valuable methane-rich biogas produced can be sent to a Combined Heat and Power (CHP) unit to generate electricity for plant operations. In some applications, 100% of the production facility’s energy requirements can be achieved.

Sulfothane™ AdvantagesSulfothane is environmentally safe, has minimal power requirements and uses a clog-free scrubber that requires no maintenance. Its compact design and small footprint allow for easy integration into new or existing biogas facilities. Sulfothane is fully automated for ease of operation, and the elemental sulfur produced allows for easy, low cost disposal compared to competing scrubbing systems.

The Ambatovy mining and refinery site, located in Toamasina, Madagascar, is one of the largest lateritic nickel mines in the world with an annual estimated production of 60,000 tons of refined nickel and 5,600 tons of refined cobalt. Ambatovy has entrusted Veolia Water Technologies to design and build a wastewater treatment plant that incorporates the largest evaporation and crystallization project within Southern Africa, not to mention one of the largest in the world. Through a state-of-the-art evaporation and crystallization process, the wastewater plant enables Ambatovy to recover ammonium sulfate as a valuable by-product in the refining process. This also allows Ambatovy to produce an additional 210,000 tons of ammonium sulfate to be sold as agricultural fertilizer thus increasing the site’s profitability.

Recovering valuable by-products Veolia provided a solution that enables Ambatovy to not only meet its production objectives by recovering valuable by-products, but also its environmental objectives by reducing effluent volume thus limiting the impact of its activity

on Madagascar’s rich and varied natural environment.

The solution includes unique HPD® evaporation and crystallization technology developed by Veolia. The process selected is comprised of a purge crystallizer that removes high chlorides from the main crystallizer section, thereby enabling the use of

more traditional, and less expensive, 316L stainless steel materials in the construction of the process vessels and equipment without the risk of chloride corrosion.

Energy efficient process The crystallization process, utilizing evaporation, occurs over three stages and is very energy efficient. First, the initial energy input of low pressure steam (43 tons per hour) results in a vapor that provides the energy input, as heat, to the subsequent stages. Then vapor is condensed and recovered as process condensate and returned to the

condensate system. Ultimately, the plant is capable of recovering 36 tons per hour of dry ammonium sulfate from an initial liquid inlet feed of 160 tons per hour.

The performance of the plant is also enhanced by its robust structure and systems design. The structures, 10m x 10m and 17m high in size, are

designed to withstand 280 km/h hurricane winds, as well as mild earthquakes caused by nearby fault lines. Additionally, in order to avoid shutdowns and ensure optimization during the cyclone season, redundant systems have been included for the pumps and vessels.

Contribute to economic and social development Veolia was capable of overcoming the challenge that the remote location of the site presented. Due to its remoteness, all equipment was transported to Madagascar resulting in a modular construction and assembly approach to the crystallizer section of the plant. The Ambatovy plant is not only one of the most ambitious industrial projects in Madagascar but also Sub-Saharan Africa.

A new technology solution to the challenge of removing sulfate from mine effluent by combining chemical precipitation and nanofiltration is drawing attention on four continents. Recently completed pilot projects in North and South America have generated interest from mining companies in search of cost-effective breakthroughs. In Europe, nanofiltration at iron mines delivered cost, performance and maintenance benefits that outperformed the original design. In Africa, the technology’s water recovery capability has created a stir in drought-stricken countries. The proprietary process, developed by Veolia Water Technologies, responds to increasingly stringent regulations limiting sulfates in surface water discharges as well as increased mining industry interest in the reuse of mine water for beneficial purposes. The improved method lowers sulfate levels in mine water effluent below 100 mg/l, generating a clean water effluent for reuse or discharge.

Recovery: affordability key The first step in the process uses Veolia’s Multiflo™ system equipped with its Turbomix™ reactor to reduce sulfate to less than 1,800 mg/l. The first-stage effluent is then treated with calcium and an aluminum-based salt in a second system. This second-stage process precipitates sulfate as a highly insoluble calcium sulfoaluminate mineral known as Ettringite. This step reduces the dissolved sulfate in

the effluent to less than 100 mg/l. The excess sludge from the system is pumped to a third smaller system, which serves as a chemical regeneration tank. This step recovers more than 95% of the aluminum-based salt from the precipitated sludge for reuse in the treatment process. This is key to cost-effectiveness. Reusing the recovered aluminum in the treatment process instead of fresh aluminum avoids a six-fold increase in chemical costs.

Fast results The technology’s performance is turning heads, both for its efficiency and its speed. At a major copper mine in South America, water from a mine tailings pond with average sulfate concentrations up to 2,900 mg/l were reduced to less than 50 - 60 mg/l, after blending the treated membrane reject with the permeate. In North America, water from a coal mine with levels as high as 1,800 mg/l were reduced below 100 mg/l within 25 minutes. The recent developments have been built

on experience with nanofiltration at subsurface iron mines in eastern France where high-quality drinking water was produced from treating high sulfate concentrations formed in groundwater following the mines’ closure.

In Africa, particular interest has been expressed in the technology’s ability to increase water recovery from 60% to as high as 98%, depending on the original water quality. In addition to the positive response at the North and South American pilot sites, other companies have expressed strong interest in testing the technology in coming months. �

Managing the increasing sludge volumes generated by municipal and industrial water and wastewater treatment processes is a worldwide major environmental challenge.

At Veolia Water Technologies, we see sludge not as a waste but as a potentially valuable resource. We apply our global technological leadership to help our clients extract valuable biosolids and produce agriculturally-beneficial byproducts. By converting sludge into energy, we help offset wastewater treatment plant operation costs.

In Denmark, the wastewater treatment plant of the future, the Billund BioRefinery, will convert wastewater sludge and organic waste into biogas for local consumption, organic soil improvers for agriculture, and bioplastics.

In Marquette-lez-Lille, France, the biogas is used to produce electricity and heat through cogeneration. The digested sludge is then dried and recovered to be used instead of coal in cement or power plants.

Designed to treat the sludge produced by the city’s eleven sewage treatment works, the Hong-Kong plant has to limit its impact on the environment. One of its objectives is to recycle the heat generated by incineration to supply the four furnaces.

Turn your sludge into resources

Wastewater Sludge as a ResourceA circular economy means that we harvest materials that appear to have little value and turn them into a valuable resource. To improve the circular economy of wastewater treatment, Veolia has optimized our BioThelys thermal hydrolysis process (THP). More than ever, BioThelys is a compact, efficient process solution for converting sewage sludge to a source of renewable energy and a usable biosolids end product.

BioThelys SystemThermal hydrolysis is the engineered application of temperature and pressure to more effectively break down sludge. Veolia’s BioThelys system is a continuous flow, batch thermal hydrolysis process. BioThelys utilizes three types of vessels (Pre-Heat Tank, Batch THP Reactors, and Buffer Tank) in a precisely-sequenced process.

At the start of the BioThelys process, ambient temperature feed sludge is continuously fed into the Pre-Heat Tank, where it is heated to approximately 212 ⁰F using captured flash steam from the Buffer Tank. The now pre-heated sludge is conveyed by a progressive cavity pump to a dynamic mixer, where live steam is introduced. Sludge is then fed continuously to the thermal hydrolysis tanks, which provide sequenced batch hydrolysis. Sludge is fed to one TH Reactor while the other reactors are either in React Mode or Drain Mode. Downstream of the TH Reactors, the depressurization of the sludge in the Buffer Tank produces flash steam, which is harnessed and sent back to the Pre-Heat Tank.

The BioThelys TH Reactors treat sludge for 20 minutes or more at a temperature that ranges from 310 to 329 °F and at a pressure between 78 and 101 psia. These conditions efficiently break down the sludge and produce a pre-treated product that is more biologically available. In conjunction with anaerobic digestion downstream, BioThelys can create up to 40% more biogas and biomethane – a renewable source of energy. And BioThelys frees up treatment volume in the anaerobic digester. The resulting sludge complies with Class A standards and can be utilized broadly for beneficial agricultural and commercial use. BioThelys is therefore a key tool for making the wastewater treatment plant its own circular economy and advancing the wastewater treatment process toward energy neutrality.

Modularized yet CustomizableVeolia has now optimized the BioThelys system to be completely modularized. BioThelys is now an extremely compact, completely pre-fabricated, pre-wired, pre-piped and easily erectable system so that on-site construction is minimized.

Despite being modular, BioThelys is still completely customizable to the client’s needs. Process equipment is sized to fit site-specific requirements. BioThelys thus provides a plug-and-play system specifically tailored to a client’s demands.

Advantages of Dynamic MixingA key feature of BioThelys is the use of live steam dynamic mixing. Using robust dynamic mixing, BioThelys treats sludge with up to 22% dry solids (DS) content.

The ability to treat drier sludge has a number of significant cost advantages to the client. First, it allows a more efficient consumption of steam, thereby saving significantly on energy. It also allows Veolia to reduce the size of the Pre-Heat Tank and allows the client to size smaller, more compact sludge storage bins. BioThelys’ feed pumps can also be smaller, because they are conveying more sludge and less water. Finally, by the ability to treat sludge to 22% DS – readily achievable by many dewatering systems – BioThelys eliminates the need for post-dewatering dilution. BioThelys thus makes the best use of a client’s dewatering equipment and water resources.

The Veolia AdvantageAs a worldwide leader in water, wastewater, and biosolids treatment, Veolia has the expertise and technologies to evaluate and address the entire treatment process, including BioThelys. Veolia has the ability to address the whole wastewater plant – including physical/chemical treatment, biological treatment, separations and dewatering, filtration, digestion, sidestream treatment, resource recovery, polymer optimization, biogas treatment and utilization, and other systems that are not isolated from thermal hydrolysis, but work in concert with THP. By taking the larger view of the client’s needs, Veolia is able to effectively provide a total solution that can transform the wastewater treatment plant into a resource recovery tool to serve the new, circular economy. �

More than 30 years after its introduction, DenseSludge™ is still going strong.

The technology enables mines to successfully reduce the cost of water treatment and sludge management from their Acid Mine/Rock Drainage (AMD/ARD) systems. AMD/ARD from operating mines and abandoned mine sites require treatment to prevent adverse impacts to rivers and streams, which can produce significant volumes of sludge. Many AMD/ARD systems operating in the U.S. face increasing constraints on their sludge storage capacities whether they are impounding the sludge

above or below ground.The DenseSludge™ recycle process forms particles that settle quickly, dewater readily, and hold little water. The result is a reduction in sludge generation by nearly 90% and production of a drier sludge, which reduces the volume of water that returns to the mine pool for re-treatment. The technology has enabled mining companies to extend the life of existing sludge storage facilities and reduce requirements for building of new storage.

First mining applicationInitially developed to treat metal bearing wastewaters in the steel industry, the first application at a

mine came in the mid-1990’s. The mine’s owner, a producer of high-BTU bituminous coal in the United States, sought a solution for better sludge management at the mine site, located in the Eastern panhandle of West Virginia. A 2,000-gpm demonstration plant retrofitted by Veolia to an existing AMD treatment facility demonstrated the benefits of the DenseSludge™ process and provided design criteria for a new, larger facility.

The new full-scale facility was constructed downstream of the demonstration plant on a former coal refuse disposal site. Still operating today, the facility treats

Still getting the sludge outEnduring DenseSludge™ process reduces volumes by 90%


effluent from two deep well pumps, surface runoff and coal refuse leachate. Although designed for a flow rate of 9,000 gpm, operational experience has shown that the plant can handle more than 12,000 gpm.

The plant has enabled the mine to achieve consistent compliance with the discharge limitations. Cost savings are generated from reduced sludge volumes, by as much as 90%, as well as reduced water treatment, gypsum deposits on treatment equipment and tanks and lime usage.

Non-conventional solutionWhile the DenseSludge™ process itself is not new, sophisticated automation, including advanced online monitoring, measuring and control technologies, provide highly efficient AMD wastewater treatment, requiring minimal input to operate the plant.

The process differs from conventional metals treatment in a number of ways. The most significant difference is the method by which the alkali source is added. In conventional treatment systems, the alkali is added directly into the influent to achieve a desired pH setpoint. Generally, that setpoint is the pH at which the minimum solubility occurs for the target metal(s), or at the pH where discharge limitations can reliably be met.

In the DenseSludge™ process, the alkali source is combined with recycled sludge before being combined with the influent. The sludge particles react with the alkali to provide attraction sites for the removal of metals. This causes the sludge particles to become layered like an onion and enhances crystallization. The net effect is that the sludge consists of particles that are more crystalline and less amorphous than those created in a traditional AMD/ARD treatment

system. Crystalline sludge carries less water and more solids per unit volume and is therefore denser and dewaters better, resulting in a decrease in sludge volume.

Through a series of steps, the continued recirculation of sludge ultimately converts the metal hydroxides to oxides. Sludge for recirculation is withdrawn from the solids settling unit and pumped to the sludge-conditioning tank where it combines with the alkali source.

The resultant mixture of sludge and alkali is then directed to a neutralization tank where it combines with the influent. For typical AMD/ARD applications, the neutralization tank is aerated to oxidize iron from the ferrous to ferric state. The demand for alkali is controlled by the system pH setpoints. The recirculation

of the sludge enables the system to utilize unreacted alkali in the sludge, enabling more rapid and efficient dewatering and pumping and minimizing lime usage and its associated cost.

Sludge generated in the solids settling unit is recirculated constantly at a rate sufficient to meet the constraints of the DenseSludge™ process. To maintain the system’s equilibrium, the sludge is removed from the system periodically when it reaches a certain high density set-point. A number of methods are used to dispose of the sludge, most typically into directional boreholes.

Conserving natural resourcesThe well-proven technology continues to deliver impressive results. In Pennsylvania, a Veolia- designed treatment facility enabled the state’s Department of Environmental Protection to recently achieve its goal of restoring the water quality of the Bennett Branch tributary of the Susquehanna River to sustain sport fishing. The facility treats highly polluted AMD from four underground coal mine complexes that had been draining into Bennett Branch and its tributaries.

To treat the AMD, Veolia conducted treatability studies and designed a centralized treatment process and system based on DenseSludge™ technology. Veolia partnered with Civil & Environmental Consultants, Inc. (CEC) for the design of the civil work, including design of the collection system, sludge disposal system, a polishing basin for the effluent and building architecture. Veolia’s work scope included the treatability studies, process design, equipment specifications, general plant layout, the basic mechanical design for the treatment plant, and electrical and instrumentation/controls for the entire project. Veolia also assisted with startup of the treatment process.

Treating an average of 2,000 gallons a minute and operating 24/7, the DenseSludge™ system has enabled the facility to meet its highly stringent discharge parameters and allowed the water quality of the Bennett Branch to be restored to a level that supports a viable sport fishery.

Veolia-installed DenseSludge™ AMD/ARD treatment systems worldwide, including more than 10 in the United States, are enabling mines to comply with discharge restrictions and reduce costs while preserving precious water resources. �
