: 2 The Selected Dilution For Bod5 Test Should Be Such That The Residual Do Is At Least 1 Mg L And Do Depletion Should B 1 (15.22 KiB) Viewed 27 times

2. The selected dilution for BOD5 test should be such that the residual DO is at least 1 mg/L, and DO depletion should be at least 2 mg/L. Assuming initial Do of 8.6 mg/L, calculate the range of BODS that can be measured by a dilution of 1 ml sample in a 300-ml BOD bottle. [4 marks)
