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.

Problem 4
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 20,000 mg/L
and the volume of sludge is 100 m3. After filtration the sludge solids concentration is 350,000 mg/L. Assume that
the sludge does not change density during filtration, and there is no accumulation of sludge in the filtration
device. Using the mass balance method, determine the volume of sludge after filtration.
