Difference btw bod and cod
WebBiochemical Oxygen Demand (BOD) is a way to measure organic pollution in water by looking at the rate at which micro-organisms in the water use up dissolved oxygen when they metabolize the organic pollutants. For each sample, dissolved oxygen (DO) is tested at the beginning and end of a 5-day, in-the-dark incubation at 20ºC.
