Taste and Odour Event Identified by PeCOD

Featured Case Study:
Taste and Odour Event Identified by PeCOD

A drinking water utility in Florida treats groundwater from an extensive wellfield system containing 48 different wells, as well as surface water from a local creek reservoir. Due to the large number of sources, overall influent quality varies greatly. This presents a need to constantly monitor influent water quality, and use feedback loops to optimize […]

Our Annacis Research Centre researchers have remarked that PeCOD® produces results very quickly, which allows them to complete research more rapidly. They have also been impressed with the fact that it doesn’t use harmful chemicals, reducing safety risks to researchers and to the environment. They have also found that the PC Titrate equipment is very effective. It gives extremely accurate results, is well designed, and works automatically, saving researcher time. We are thankful to the University of British Columbia and MANTECH for the donated equipment, and look forward to its role in advancing research in the region.

Aurora Water (Aurora, CO) has been analyzing low level chemical oxygen demand (COD), at source and drinking water levels, using the photo-electrochemical PeCOD® instrument as part of Water Research Foundation Project #4555. We are excited to have a rapid method available to determine low level COD, and look forward to further understanding how the information that is gathered may help with operational decision making and treatment optimization.

CWRS has been experimenting with PeCOD® applications since 2011. These applications have included monitoring of wastewater in Northern communities, and source and treated drinking water monitoring. Most significantly, the PeCOD® has been able to give our group additional insight into drinking water biofiltration performance by quantifying organic matter removal across biofilters that was largely unrealized by measuring dissolved organic carbon alone. PeCOD® is now being integrated into many of our projects that require a measurement of natural organic matter.

Frequently Asked Questions

What is the primary mechanism of PeCOD® chemistry?

The primary driver of the peCOD method chemistry is advanced oxidation induced by photocatalysis with Titanium Dioxide (TiO2). Pure TiO2 is only photo-active at wavelengths below 380 nm. This is because a certain amount of light energy is required to bump the electrons around and cause the behaviors that we associate with photocatalysis. The UV LED in the PeCOD® COD Analyzer operates at a peak wavelength of 365 nm, with a minimum 360 nm and maximum 370 nm, ensuring that efficient photocatalysis is achieved.

What is total organic carbon?

TOC (Total Organic Carbon) is the amount of carbon based organic contaminants in a water system. TOC does not identify each specific organic contaminant present, but rather an absolute quantity of all carbon-bearing molecules. In other words, TOC is a way to measure organic contaminants that may pose a threat to drinking water or wastewater systems.

How does the PeCOD® method compare to BOD, TOC, and conventional COD?

BOD and COD methods differ from TOC because they measure the amount of oxygen that is depleted by organic species in water. There are several common methods to test wastewater and drinking water for organic pollutants, natural and chemical.  Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD) and, Total Organic Carbon (TOC) compromise the three main methods of testing water samples.  BOD and COD methods differ from TOC because they measure the amount of oxygen that is depleted by organic species in water.  Moreover, TOC is a measure of all carbon (both organic and inorganic), rather than the oxygen that is reduced by these species.  As written by a TOC manufacturer, “TOC on its own sheds no light on the oxidizability of the measured carbon or the amount of oxygen needed for its biodegradation.”  Specific to COD, it measures the reactive fraction of the TOC.  This is also known as oxidizability in the European Union. View the full article: Comparison of COD, BOD and TOC Methods for organics, which summarizes the advantages and disadvantages of the COD, BOD and TOC methods, and compares them to the PeCOD method.
