a treatment plant receives 20,000m^3/day of a wastewater containing 115mg/L of suspended solids and 230mg/L of BOD. The effluent contains 20 mg/L of solids and 20 mg/L of BOD the biological treatment process produced .32 kg of bacterial solids per kg of BOD removed
a- Calculate the kg/day of sludge process if the sludge is 8% solids (by weight)
b- Calculate the m^3/day of sludge produced if the sludge density is 1120kg/m^3
