Determination of Biochemical Oxygen Demand (BOD5)

198 ( 30.5 mg Oxygen/L is based on a 2 % dilution of GGA (6 mL/300). It is important not to use multiple dilutions which use other than 6 mL). Seed is then added and the bottle is filled with dilution water. These bottles are incubated and BOD is determined similar to sample bottles. 3. The acceptable BOD5 value of the standard is 198 ( 30.5 mg/l. ................
