Attempts to anticipate and quantify the oxygen depletion effects of organic wastes on receiving water have been ongoing for more than 150 years. The biochemical oxygen demand (BOD5) test is widely believed to provide the best estimate of the oxygen demand

Chemical oxygen demand (COD) is the amount of dissolved oxygen that must be present in water to oxidize chemical organic materials, like petroleum. COD is used to gauge the short-term impact wastewater effluents will have on the oxygen levels of receiving

May 2017. Chemical oxygen demand (COD) is a critical waste treatment measurement in everything from municipal systems to food manufacturing waste streams. Performing COD testing the right way is important in determining wastewater treatment effectiveness and can help diagnose any problems in treatment. In this blog, we’ll cover what chemical oxygen
