A water contains 50.40 mg/L as CaCO3 of carbon dioxide, 190.00 mg/L as CaCO3 of Ca2 and 55.00 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 2.935 m^3/s. Assume that the effluent water contains no carbon dioxide, 30.0 mg. L^-1 as CaCO3 of Ca2+ and 10.0 mg. L^1 as CaCO3 of Mg2+. Be sure to calculate the mass of CaC03 and Mg(OH)2 sludge produced each day.
