Analysis of PeCOD® COD Technology and Comparison to Dichromate Method

Home / Resources for MANTECH Products / BOD Analysis Resources / Analysis of PeCOD® COD Technology and Comparison to Dichromate Method

The main objective of this report was to determine if a correlation exists between peCOD technology and the dichromate method of estimating Chemical Oxygen Demand (COD). Additional investigations described in this report were: to identify whether particle size in water samples affects the estimate of COD obtained by peCOD analysis and, to identify whether peCOD analysis is accurate when testing COD standards. Various wastewater samples were collected and tested using the peCOD and dichromate COD methods; additionally, COD standards were prepared and tested to ensure precision of the estimation methods. The peCOD COD procedure does not require the use of any hazardous materials and disposal methods are inexpensive and straightforward.
