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.

Rapid, safe and green analysis

• Performs rapid advanced oxidation coupled with green electrochemistry to measure oxygen demand
• No mercury or dichromate required
• Protects health of people and environment
• Oxidation efficiency parameters can be tuned for both COD and BOD using the same sample

Core Technology in the PeCOD® Sensor

• UV-activated nanoparticle TiO2 (titanium dioxide) photocatalyst
• Coupled to an external circuit

Powerful oxidation potential ensures: 

• Rapid results
• Complete oxidation of virtually all species
• A true measure of COD and BOD

Real user benefits of the online COD, BOD and TOC analyzer:

• Green chemistry with no hazardous reagents protects operators and the environment
• Save time and money through process optimization
• Full autonomous control, operators simply set sampling frequency and press start
• Set sampling intervals with built-in features to minimize human interaction
• A true measure of COD and estimated BOD that does not rely on optical or surrogate measurements
• Combine analysis of pH, alkalinity, conductivity, ammonia and more
