A stаbilizаtiоn pоnd is tо be designed for а community with a population of 3,000 people, to provide secondary treatment. Primary treatment of the wastewater is to be provided. Pertinent design data for the facility are as follows. Solve each problem to determine the design parameters. Raw wastewater flow rate: 90 gpcd Influent BOD5: 200 mg/L Primary clarifier BOD5 removal: 30% BOD5/Ultimate BOD: 70% of stabilization ponds in parallel: 2 Pond length to width ratio = 3:1 Pond depth: 5 feet Winter operating temperature: 45 °F (=5.56 °C) Algal toxicity factor (f) = 1 Sulfate concentration is less than 500 mg/L; so f´=1 Temperature coefficient (θ)= 1.07 (5 pts) Calculate primary clarifier effluent ultimate BOD (L0, unit: mg/L) (Hint: first calculate BOD5 (mg/L)). (5 pts) Determine total stabilization pond volume required (V, unit: ft3) (Hint: C=0.0047) (5 pts) Determine the total stabilization pond surface area (A) required (acres). (Hint: 1 acre = 43,560 ft2). (5 pts) Determine width (ft) of each pond in 5 ft increments. (Hint: each pond has identical width).
Yоu hаve been given а jоb tо design аn aerobic digestion system to treat waste activated sludge (WAS) produced by a local activated sludge process. Pertinent design data for the facility are as follows: Mass flow rate of sludge (TSS or T): 4,000 lb/day Digester liquid temperature: 20 °C Influent BOD5 (Si): 3,000 mg/L Solid concentration in the feed sludge (Xi): 2.5 % (=25,000 mg/L) Specific gravity of the feed sludge (SG): 1.01 VSS/TSS (PV) = 0.8 VSS reduction goal through digestion: 40% Cell tissue oxygen requirement: 2.3 lb O2/lb VSS destroyed Fraction of influent BOD consisting of primary solids (Y) = 0.35 Sludge concentration is 70% of the incoming thickened sludge concentration; so the biomass concentration in the aerobic digester is 17,500 mg/L. Reaction rate constant (kd) = 0.10 day-1 Mixing and aeration system: diffuse air Diffuser efficiency (Oxygen transfer efficiency): 10% Specific weight of water (
