Online COD, BOD and TOC analyzer

Real time, hands free results

The patented PeCOD technology of the online COD, BOD and TOC analyzer uses a unique nanotechnology-based photoelectrochemical method to measure bulk oxidizability of a sample stream. The Titanium Dioxide photosensor’s strong oxidation power rapidly breaks down all reactive organic matter, delivering results in just 10 minutes.

Online PeCOD® for chemical oxygen demand (COD) and estimated biochemical oxygen demand (BOD) analysis provides real-time results to improve process control, optimize treatment, and ensure compliant discharge.

Nanotechnology based method

MANTECH’s PeCOD® analyzer uses a nanotechnology-based method that delivers empirical results, unlike optical or surrogate techniques used to measure the oxidizability of organic matter in water.
