The essential nature of vitamins and minerals for human health was demonstrated more than a hundred years ago. Biochemical 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. These standards are reflected in terms of five-day biochemical oxygen demand BOD5 total suspended solids TSS removal and pH.
The treated effluent may be suitable for discharge to surface waters or possibly for use on land. 10WM0321 Guidance for the selection of water supply pipes to be used in brownfield sites. COD contrasts with biochemical oxygen demand BOD which relies on the use of microorganisms to break down the organic material in the sample by aerobic respiration over the course of a set incubation period typically five days.
