Real Time Monitoring for Effective and Sustainable Industrial wastewater

Treatment and Compliance

15 min COD analysis

• We would like to thank National Research Council and IRAP for making this visit possible

• From NRC in attendance are:• John McDougall

• Carole Morneau

• Andrew Bauder

COD and BOD

• The standard BOD test requires five days to complete - unable to provide continuous monitoring of organic load.

• BOD measures the oxygen consumption from biological matter in the wastewater

• COD measures the oxidizable organic mater in the wastewater

• COD is often used for BOD screening.

• Current regulated method requires the use of Mercury and Dichromate

• Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) are ubiquitous measurements of overall water quality.

Regulatory Requirements

• Determination of COD to measure organic matter in wastewater effluent is required under the EU Urban Waste Water Directive 91/271

• Mercury is to be prohibited for use within Sweden as of 2016• http://www.government.se/sb/d/11459/a/118550

• European Chemical Authority Helsinki (ECHA) has labeled Dichromate as a serious chemical of serious health concern.• Scheduled to be banned September 2017

Actions to Meet Regulatory Requirements• RWS-CIV

• Dutch MOE began testing & validating an alternate COD method to address regulatory challenges

• …from MANTECH

• KAPPALA Wastewater Association, Sweden. • Published “Invitation to Tender for the Provision of a Pre-Commercial Procurement of a

Mercury Free COD analysis method for Wastewater and Waste Products”• Funded By VINNOVA• MANTECH’s technology selected to develop and commercialize an alternate COD method for

municipal WWTP’s

• Ministry of the Environment and Climate Change (MOECC), Ontario Canada. • Have already released E3515 after a 20 month validation• http://www.mantech-inc.com/wp-content/uploads/2014/10/MOE-PeCOD-Method.pdf

What is the alternate COD method?

• PeCOD – Photoelectrochemical COD

• Patented sensor consists of a UV-activated TiO2 (titanium dioxide) photocatalyst

• Powerful oxidizing potential of TiO2 gives a true measure of COD

• COD analysis method of Ontario Ministry of Environment (Method E3515)

• COD analysis can now be done by any operations staff member

PeCOD Technology

• Uses a TiO2 sensor

• TiO2 is a well established, powerful and versatile photocatalyst (3.2 V)

• TiO2is illuminated with UV light, and becomes a powerful oxidant

• Oxidizes the organics in a sample, and directly measures the amount of oxidation

Load. Start. Done.

What are the Challenges to Address?

1. To meet regulatory requirements that are to be implemented

2. Effective waster water treatment – requires effective monitoring

3. Optimize industrial waste water treatment

4. Promote sustainability, protect the environment and protect the public

Where is MANTECH NOW1. New innovation allows for quick and safe COD analysis2. Current development projects are applied to laboratory and municipal sites

What we would like to Investigate?1. Develop innovative technology for industrial applications

Why Work With MANTECH to Develop and Commercialize the COD Method for Industrial Applications

• Peace of mind• Fine Avoidance

• Protect the Public

• Protect the Environment

• Compliance

• Process optimization

Pulp & Paper ExampleA Pulp and Paper company in Chile. After running the PeCOD for 12 months, it gave the ability to optimise the ClO2 usage

This resulted in savings of US$6,341/dayWHY?1. Lower reagent consumption2. Lower amount of organics to treat3. Energy efficiency Gains

• The initial investment was justified through effective compliance and improving the health & safety of users.

• In addition, has resulted in process optimization with financial savings >US$2M/year!

“We moved from the COD vials to the PeCOD® primarily because it allowed us to run our process more efficiently and further

adjustments to our process could be made up to ten times a day. With the COD vials, only 3 or 4 adjustments could be made. This

increase in efficiency and turnaround time in sample analysis has easily paid for the system, not to mention the added benefit that we're no longer using carcinogenic chemicals to test for COD. We

have also seen a reduction in cost of consumables and waste disposal.”
