The samples then cool and the samples are tested using a spectrophotometer. The chemical oxygen demand value will be read in mg/L for both total COD (tCOD) and soluble COD (sCOD). For samples with a concentration of 0 to 150 mg/L, use the low range COD vials. For higher concentrations the high range COD vials (0-1500 mg/L) should be used.
COD (Chemical Oxygen Demand) is a term used to measure the quality of water. It is a measure of water pollution resulting from organic matter. This parameter is defined as the amount of oxygen (in milligrams per liter of sample) required for the oxidation of all organic matter contained in a water sample.
The Chemical Oxygen Demand (COD) test predicts the oxygen requirement of the effluent and is used for monitoring and control of discharges, and for assessing treatment plant performance. The impact of an effluent or waste water discharge on the receiving water is predicted by its oxygen demand.

We explain the differences between biological oxygen demand & chemical oxygen demand. Yesterday afternoon I finished up some stormwater training with an old client of ours who changed some staff recently. I was brought in for some basic environmental training, and one of the topics we covered was their NPDES stormwater permit..

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 ).
