COD describes the amount of oxygen needed to chemically stop working pollutants, although BOD signifies the quantity of oxygen necessary to stop working organic and natural pollutants biologically with microorganisms.
Strong wave motion in marine coastal areas may well guarantee aeration, Whilst gentle wave action and riffles may or may not be adequate, based on the depth of the drinking water and rigor of mixing. Screening in these conditions must be complemented with actions of DO concentrations (see Methods to Measure tab).
