For the measurement of the BOD of a wastewater sample from textile industry, five different dilutions (0.5%, 1%, 2%, 5% and 10%) of 1 L are prepared, with the addition of 2 mL of seed. Three different dilutions (0,5%, 2% and 5%) are used for seed corrections. The results of DO measurements are given below. Calculate the BOD5 concentration of the sample.
7235 A river before its entry into a town had a discharge of 100 litres per seconds and 20 mg/L as the concentration of a conservative parameter. The town's waste water outfall having 200 mg/L concentration of the same conservative parameter raised the river concentration of 50 mg/L after a complete mix with the river water. Determine the dilution ratio resulting from t said waste water outfall. discharge of the

The BODs of a domestic wastewater sample is considered to be about 200 mg/l and the DO in it is measured as 0 mg/L. The laboratory staff are preparing to set up a BOD test to determine the actual BOD of the sample. The DO of the dilution water was measured to be 9 mg/I. Which of the following volume ratios of (total volume of BOD bottle = 300 mL) / (volume of wastewater sample) would be most appropriate to use in setting up the BOD bottle for incubation? Select one among the following: (a) 20/1; (b) 50/1; (c) 100/1; (d) 500/1. Justify your selection
