@CEE a good approximation for the kinetic temperature correction is 0.21 per day, assuming a temperature correction (θ) coefficient of for activated sludge at temperature range 21 - 30 deg C. K_T = k_20(θ)^T-20. The BOD(5) is most nearly 195 mg/L. The ultimate BOD (L0) is approximately 160 mg/L. We can compute the for various system such as : Trickling Filter , Biotowers, Rearation (independent of the temperature). For an activated sludge θ = 1.136 (T= 4 - 20 deg C) and θ = 1.056 ( T= 21 - 30 deg C). Source : PE Environmental Reference Handbook Version 1.3 Page 37 of 197.
Determine rhe 5 day BOD for a 15ml sample that is diluted with dilution water to a total volume of 300ml when the initial DO conc. is 8g/ml and after 5 days, has been reduced to 2mg/l... Sir iska answer kya aayega.??

dilution factor kse nikalna h iska
L value is getting wrong for me L value is getting 74.38
