Measuring Biochemical Oxygen Demand (BOD) is a method used for:
Estimating the amount of organic matter in sewage water
Working out the efficiency of oil-driven automobile engines
Measuring the activity of Saccharomyces cerevisiae in producing curd on a commercial scale
Working out the efficiency of RBCs about their capacity to carry oxygen
According to the text, the BOD test measures the rate of uptake of oxygen by micro-organisms in a sample of water. Thus, indirectly, BOD is a measure of the organic matter present in the water . It is primarily used to determine the polluting potential of sewage water; the greater the BOD, the more the organic matter .
