OZONE Water Sanitation Technology for Healthier Pool EnvironmentsCopyright 2011

zone zone TTechnologyechnology was discovered in the mid 1840’s by Christian Friedrich Schönbein, a German-Swiss chemist. T The first drinking water treatment plant was built in Oudshoom, Netherlands during Americas’ “Depression of 1893”.

In 1906, the first municipal water treatment facility was built in Nice, France specifically to use ozone as a disinfectant. By 1977, there were over a thousand ozone drinking water treatment plants in Europe. The market for it’s oxidation power spread from France, Germany, Netherlands and other European countries making it into the pool and spa industry in the early 1950’s and in the United States since about 1975.

In 2001, the FDA officially allowed the use of ozone as an antimicrobial direct food additive and as a surface disinfectant in the food chain.

Today, 2011, the Centers for Disease Control (CDC) have drafted changes within the Model Aquatic Health Codes (MAHC), a guideline for improving the safety and efficacy of sanitation for public swimming venues, identifying ozone as an approved secondary disinfection system that will help to achieve this goal.

Since 1961, when the U.S. Public Health Service published a model ordinance governing the sanitation of public pools with chlorine, it has been the standard water treatment chemical in much of our industries. While chlorine is effective in reaching certain water quality standards, scientists are learning more about its limitations and hazards.

Soon, the MAHC will include a section on the importance of supplemental disinfections systems (SDSs). In the present draft only two recommended SDS technologies are listed : ozone and ultraviolet light (UV).

Why the addition? Chlorine, reigning as the standard in disinfectants on the market over 100 years, is known to be toxic to marine life, cause serious health problems (some carcinogenic), and be hazardous to the environment. It is dangerous to handle, store, extremely flammable and costly.

In swimming pools this caustic and corrosive chemical attacks organic waste turning them into highly toxic chloro-organic compounds (combined chlorine) that can accumulate to very high concentrations. Obvious signs of this are red eyes and skin rashes and should be considered signals of a much more serious risk in human health.

“Chlorine may just be the greatest crippler and killer of modern times!” Dr. Robert Carlson, Unv. Of Minnesota

Contamination in pools are caused primarily by the bathers themselves who introduce pollution in the form of urea, sweat, body oils, cosmetic products, saliva, lotions, some shampoos and soaps. Reacting with the pool chemicals substances (by products) form called “Chloramines” and “Trihalomethanes” (THMS).

““Does your pool Does your pool water have you water have you upside down?”upside down?”

Chlorine Pool PollutantsChlorine Pool Pollutants Chloramine and Trichloramine (THMS), chlorine substances such as these

contribute to many of today’s swimming pool problems.

Chloramines are responsible for the so-called "chlorine smell", or ammonia odor.

Corrosion in and around the pool are likely due to the production of these two chlorine by-products. Chloramines in the air can cause significant damage to anything metallic when they condense on metallic surfaces. These chloride forms are a harmful substance that will corrode metals, including stainless steel.

Chloraminated water can also cause rubber parts in plumbing, pumps, filters and water heaters to degrade more quickly. Chloramine-resistant replacement parts may be available.

Both can cause health problems to the skin, eyes, sinuses, mucous membranes, and throat in the pool water and in the air above the water.

These are very potent irritants, having been known to actually cause asthma in workers working in an enclosed environment, in swimming pools. COMPETITIVE SWIMMERS IN HIGH-CHLORINE POOLS HAVE INCREASED RESPIRATORY PROBLEMS.

Ozone vs UVOzone vs UVTWO COMPLETE DIFFERENT TECHNOLOGIES,

Ozone is a gas that is dissolved in water to kill microorganisms, destroy organics, and break down chloramines by oxidation. This occurs immediately at the ozone gas injection point and continues as the side-stream remixes with the main return.

UV light inactivates microorganisms and breaks down chloramines with light energy. With UV, this chloramine breakdown only happens while the water is in the UV chamber, and as long as the water has no turbidity.

While both Ozone and UV provide very effective Crypto reduction as documented by third-party testing and validation, there are distinct differences between the two technologies when it comes to other areas of concern for commercial aquatics designers and operators, with clear advantages to Ozone over UV.

Either system is in general used in combination with a small amount of chlorine dosing; not so much for crypto control, but to provide a “residual of chlorine in the pool water” as required under State Health Regulations.

Use of ozone as opposed to chlorine in swimming pools and spas is gaining popularity worldwide as people become more concerned about chlorine and chlorinated byproducts.

Ozone has been used in Olympic training pools, Nike world campus swimming pools, EPA headquarters, the Pentagon, luxury Resorts and many more.

Negative Side to OzoneNegative Side to Ozone

Disadvantage is higher cost to adapt / install the initial system.

Unfortunately, the high cost of ozone generators in the past has impeded its

growth into the market. If you consider that there have been several

generations of engineers / technicians who have been taught chemical

processes as a matter of course, it is not easy to persuade them that

switching to this "new" (to North America) technology is the way to go. As

this superior alternative to swimming pool disinfection becomes more

prevalent, expect to see more expertise at the local pool builder or pool

maintenance companies that will help you create a better environmentally

safe and healthy system for years to come.

Study Says Ozone Technology Sales to Exceed Study Says Ozone Technology Sales to Exceed $800 Million by 2015$800 Million by 2015

August 2011

A BCC Research technology market research report indicates that total worldwide sales revenues for ozone technology were $469 million in 2007, and are expected to increase to more than $800 Million in 2015, a compound annual growth rate (CAGR) of 8.1%.

The largest ozone technology segments in 2009 were water/wastewater applications. These will increase from $356 million in 2007 to nearly $600 million in 2015, a compound annual growth rate (CAGR) of 8.4%.

Sales of ozone technology in Air and gas treatment, medicine will experience moderate growth. This market segment was worth $113 million in 2007 and will increase at a 6.9% compound annual growth rate (CAGR) to reach a value of $183 million in 2015.

Cost factorsCost factorsA properly sized and installed Ozone system will provide reliable sanitation or secondary disinfection for years. Compared to UV, in particular, ozone is maintenance free, and the typical reductions in chemical demand simplify routine measurement, dosing and testing of water (and produces healthier, fresher water [1] ).  Since ozone is generated as needed on site, there is no need for storage, inventory or logistics management.

Ozone sanitation systems are safe and effective as well as cost effective.

As a rule, ozone and UV technologies are comparatively priced. Each costs approximately $30,000 for a 100,000-gallon pool, with the ozone system having the larger footprint. Operational cost will vary with the local price of electricity for either technology. However, ozone does not entail the same maintenance costs as UV. With savings from labor and reduced chlorine usage, a system can pay for itself in three to six years on a 100,000-gallon pool, depending on bather load, some are seeing returns within as little as 12 months [2] .

These units generally run in combination with a chlorine dosing system to provide a “residual of chlorine in the pool water” as required under State Health Regulations.

Home to the 2008 Beijing Summer Olympics, housing three pools. The Water Cube has an advanced water filtration system which takes into account Beijing's need to conserve limited water resources. The water filtration system runs the backwash water through a two-stage filtration system before returning it back to the pool. Engineers installed a unique breeze system that runs gently across the water to remove any trace of disinfectant aromas. Recirculation of the pool’s water is controlled using a computer that also reduces the amountof water used by more than 50 percent compared with other facilities. The facade of the water cube became so popular that there is now a one-to-one copy near the ferry terminal in Macau – the Casino Oceanus by Paul Steelman.

Supplemental CoverageWhen it comes to supplemental disinfection, many operators think UV. But there’s another poorly understood alternative that’s worth learning more about — ozone.By Beth Hamil, DEL Ozone | April 2010

As aquatics facility operators and officials look to increase the safety and health of our public recreational waters, it is clear that supplemental disinfection systems will offer strong protection. Several states have already mandated the use of SDSs for their high-risk swimming venues such as interactive spray parks, and it is likely more states will rapidly adopt the MAHC for these as well as all public aquatics facilities. With this in mind, operators and officials are wise to learn about the power of ozone sanitation.

ConclusionConclusion

Ozone (O3), also known as "Active Oxygen", is a

colorless gas with a characteristically clean, but strong

odor. Ozone is the safest and second most powerful

oxidant known to human, neutralizes contaminants or

chemically alters them, so that they can be more easily

eliminated. Today, it is the most valuable and powerful

tool in air and water purification, food preservation, and

body detoxification.
