cod digestion vials with closures Waters

Details of Chemical Oxygen Demand Test: 2mL of a water or watse water sample are added to a 16mm glass culture tube containing the digestion reagent and a catalyst. The tube is capped with a polypropylene, PTFE lined cap and heated in a block digester at 150C for 2 hours. The orange Hexavalent chromium is reduced to a greenish trivalent chromium.

2017/08/22 · 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 demand is, how to test it, and how []

2018/11/01 · Aerobic COD removal is ideal for wastewater with COD < 3000 mg/L. Anaerobic COD removal uses microbes to convert organic compounds in the wastewater to biomass in the absence of oxygen. It is a highly beneficial method because the biofuel generated from the process can be utilized as an alternative energy source for power, heating, and drying applications.
