water contains 38.50 mg/L as CaCO3 of carbon dioxide, 288.00 mg/L as CaCO3 of Ca2+ and 53.00 mg/L as CaCO3 of Mg2+. All of the hardness is carbonate hardness. Using the stoichiometry of the lime soda ash softening equations, what is the daily sludge production (in dry weight, kg/day) if the plant treats water at a rate of 56.00 MGD? Assume that the effluent water contains no carbon dioxide, 30.0 mg/L as CaCO3 of Ca2+ and 10.0 mg/L as CaCO3 of Mg2+. Be sure to calculate the mass of CaCO3 and Mg(OH)2 sludge produced each day
