PeCOD®

Chemical oxygen demand (COD)

Réf : PeCODBrand : Mantech
  • Results in 15 minutes
  • Mercury and dichromate free chemistry
  • Patented nanotechnology-based on TiO2
Technology used : COD measure based on oxidation

MANTECH’s PeCOD® COD analyzer technology provides accurate chemical oxygen demand (COD) results in only 15 minutes. The PeCOD® is available in a variety of configurations that use the same innovative technology and method : Benchtop, Portable, Automated and Online.

Green chemistry

Harmful chemicals such as dichromate and mercury are usually used in traditional COD analysis. The PeCOD® nanotechnology provides a higher oxidizing power thanks to TiO2.

Technology

The core of the technology is the PeCOD sensor, which consists of a UV-activated nanoparticle TiO2 (titanium dioxide) photocatalyst coupled to an external circuit. When a sample is introduced into the microcell containing the PeCOD sensor, the TiO2 is irradiated by UV light, and a potential bias is applied. The UV light creates a photohole in the TiO2 sensor with a very high oxidizing power and organics in the cell are oxidized.

PeCOD® & BOD5

The PeCOD® COD Analyzer technology is a proven performer in a variety of municipal and industrial wastewater applications. Recent studies have shown a strong correlation between the 15 minute PeCOD method for testing chemical oxygen demand (COD) and standard dichromate COD (CODCR) and five-day BOD (BOD5) methods. In most cases, PeCOD can be used as a BOD screening tool, providing accurate BOD estimates in just minutes versus several days.
