Mantech 15-minute COD analysis

The PeCOD 15-minute chemical oxygen demand (COD) for municipal wastewater treatment facilities from Mantech eliminates the use of hazardous dichromate reagents previously required for COD analysis. The PeCOD unit features a nanotechnology-based sensor that includes a UV-activated nanoparticulate TiO2 (titanium dioxide) photocatalyst that measures photocurrent charge originating from the oxidation of organic species contained in a sample. 519/763-4245; www.mantech-inc.com.
