MANTECH Inc. applications

MANTECH’s game-changing water quality analysis technology is revolutionizing wastewater treatment at industrial and municipal facilities worldwide. The PeCOD Analyzer provides accurate chemical oxygen demand (COD) results and biochemical oxygen demand (BOD) estimates within minutes rather than the hours or days required for standard COD and BOD testing — without the use of dichromate, mercury, acids and other harmful chemicals.

PeCOD Analyzer Improves Pulp Mill Performance, Reduces Wastewater Pollution. MANTECH’s PeCOD technology is a safe and effective solution for improving wastewater treatment and optimizing the use of chemicals in pulp and paper mills.

MANTECH’s innovative PeCOD Analyzer is helping Ontario’s craft brewers manage their wastewater more effectively. PeCOD is an integral part of the Brü Clean System, a specialized wastewater treatment process developed by Econse Water Purification Systems for the craft brewing industry. Together they helped reduce the amount of wastewater for treatment by 75 per cent. “We can accomplish in a few minutes what other companies take weeks or months to do and this lets us move straight to effective treatment solutions for our clients.” — Derek Davey, Econse Water Purification Systems.

In addition to providing 15 minute chemical oxygen demand (COD) results and biochemical oxygen demand (BOD) estimates, the PeCOD® Analyzer measures natural organic matter (NOM) in fresh and treated drinking water. The PeCOD® Analyzer does what no other technology has done before. It quickly and safely measures oxygen demand and the associated oxidative changes in organic matter in fresh and treated drinking water, at low concentrations and without the use of hazardous chemicals. A new ASTM International method for peCOD (photoelectrochemical Oxygen Demand), D8084-17, was released in September 2017.

Real Time Chemical Oxygen Demand Improves Wastewater Management. MANTECH’s PeCOD Analyzer water quality analysis technology provides food and beverage processors with accurate, real time data that enables them to make timely decisions and effectively manage their water and wastewater. The PeCOD Analyzer is a fast, green, accurate alternative to traditional chemical oxygen demand (COD) and biological oxygen demand (BOD) testing for measuring organics in wastewater. Rapid, reliable and economical testing helps companies remain in compliance with their permits and respond quickly when they are not.

PeCOD® is the only Chemical Oxygen Demand (COD) analysis technology to use the powerful UV-activated nanoparticle TiO2 (titanium dioxide) photocatalyst which is at the core of the system. The high electrochemical potential of the TiO2 gives it a substantial advantage over the modest chemical potential generated by the dichromate method. The UV light creates a photohole in the TiO2 sensor with a very high oxidizing power and organics in the cell are oxidized. PeCOD® is extremely accurate across a broader range of organics. The powerful oxidizing potential of UV-illuminated TiO2 ensures that virtually all species will be fully oxidized giving a true measure of COD.
