http://americanwatercollege.org • • This question comes from the California Wastewater grade 3 certification exam sample questions that can be found here: http://www.swrcb.ca.gov/water_issues/... • • The problem reads: • An activated sludge plant generally operates well with an F/M Ratio of 0.65 lbs COD/day/lb MLVSS. Given the following information, show a determination of the concentration of MLSS that should be maintained: • • Average Plant Flow Rate 4.0 MGD - Normal RAS Flow Rate 2.0 MGD • Aeration Basin Volume 1.25 MG • Final Clarifier Volume 0.5 MG • Primary Effl. COD Conc. 300 mg/L - Final Effl. COD Conc. 56 mg/L • Primary Effl. SusSol. Conc. 105 mg/L - Final Effl. SusSol Conc. 20 mg/L • % Volatility of MLSS 70
