Problem 4In water and wastewater treatment processes a filtration device may be used to remove water from the sludgeformed by a precipitation reaction. The initial concentration of sludge from a softening reaction is 20,000 mg/Land the volume of sludge is 100 m3. After filtration the sludge solids concentration is 350,000 mg/L. Assume thatthe sludge does not change density during filtration, and there is no accumulation of sludge in the filtrationdevice. Using the mass balance method, determine the volume of sludge after filtration.
A wastewater treatment uses an activated sludge process for secondary treatment of 0.3 m^3/s of primary effluent. The activated sludge has a biomass concentration of 2,100 mg VSS/L, and the return activated sludge line (also known as RAS) concentration is 10,000 mg VSS/L. The substrate concentration in the primary effluent is 220 mg BOD5/L. The F/M ratio for the activated sludge tank is 0.52 mg BOD5 × mg VSS^-1 × d^-1 , and the cell residence time is 9.0 d. (a) What is the volume of the activated sludge tank?(b) What is the waste line (also known as WAS) flow rate?(c) What is the flow rate of the effluent from the entire system?(d) What is the hydraulic residence time for the activated sludge tank? Hint: You will need to also write a mass balance for biomass X around the secondary clarifier, and a flow balance around the secondary clarifier, as part of the solution.

5. In water and wastewater treatment processes a filtration device may be used to remove water from the sludge formed by a precipitation reaction. The initial concentration of sludge from a softening reaction is 2 percent (20,000 mg/L) and the volume of sludge is 100 m3. After filtration the sludge solids concentration is 35 percent. Assume that the sludge does not change density during filtration, and that liquid removed from the sludge contains no sludge. Using the mass balance method, determine the volume of sludge after filtration.
