Study Notes
BOD Determination
- The volume of the water sample initially taken for BOD determination is 250ml.
- The concentration of the thiosulphate solution used in the dissolved oxygen determination is 0.025N.
- The bottles were incubated at 20°C for BOD determination.
- The BOD value of the waste water sample is found by measuring the oxygen depletion over 5 days.
