peCOD is the fastest available method for quantifying chemical oxygen demand (COD), providing operators with real time data needed to make timely, impactful decisions that enhance environmental protection while generating substantial savings on chemical and energy use.
peCOD nanotechnology provides a higher oxidizing power and none of the risks associated with harmful chemicals such as dichromate and mercury used in traditional COD analysis. It’s safe and simple to use for any laboratory or operations staff member at any point in the process.
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 is extremely accurate across a broad 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.
The PeCOD® COD Analyzer technology is a proven performer in a variety of municipal and industrial wastewater applications. 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.
The PeCOD® COD Analyzer is available in a variety of configurations that use the same innovative technology and method. peCOD combines robust performance and flexibility to suit the needs of your laboratory or process operations.
