There are many standardized approaches for measuring COD, but the most typical will be the dichromate reactor digestion approach which includes the reaction of sample with potassium dichromate in a very sulfuric acid solution.

By removing organic and natural supplies from wastewater with coagulants and flocculants, the competition for dissolved oxygen amongst maritime lifestyle and bacteria is lessened, as microorganisms no longer have “food stuff” to thrive.

The concentration of oxygen in water is frequently reported either as being the concentration in mg/L or as being the percent saturation. DO concentrations and percent saturation are associated, but not equivalent.
