Chemical oxygen demand. In environmental chemistry, the chemical oxygen demand ( COD) is an indicative measure of the amount of oxygen that can be consumed by reactions in a measured solution. It is commonly expressed in mass of oxygen consumed over volume of solution which in SI units is milligrams per litre ( mg / L ).

COD is a measure of total oxygen used to break down both biologically-used organic matter (indicated by BOD) and inert organic matter. Because BOD measures oxygen in a biological process that may take 5 days, it is a much slower measuring process compared to COD, which can only take a few hours.

The LAR QuickCODultra is an online COD/TOD measurement system for the measurement of chemical oxygen demand and suitable for the most difficult wastewater applications. Combustion at °C

24 holes for 16mm diameter vials COD VARIO Tube Tests The Lovibond ® COD VARIO tube tests use a sealed tube system based upon the standard dichromate method and can be consindered as an estimate of the theoretical oxygen demand, i.e the amount of oxygen consumed in total chemical oxidation of the organic constituents present in the water.

demand for various soy food products. In 2014, the top 50 soybean food companies processed 9.6 £ 108 kg soy-beans. Generally, 7–10 m3 of wastewater is generated when 1000 kg soybean is processed, and the resulting chemical oxygen demand (COD) is greater than 20,000 mg O 2/L. Therefore, the amount of wastewater
