Question

A water contains 50.40 mg · L−1 as CaCO3 of carbon dioxide, 190.00 mg · L−1 as CaCO3 of Ca2+ and 55.00 mg · L−1 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−1) if the plant treats water at a rate of 2.935 m3 · s−1? 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 CaCO3 and Mg(OH)2 sludge produced each day.
