Water defined by the following analysis is to be softened by excess lime treatment in a two- stage system: HCO; = 150 mg/L as CaCOs so = 120 mg/L Cl=71 mg/L CO2 = 4.5 mg/L Ca+ = 64 mg/L Mg = 37 mg/L Na* = 29 mg/L The plant is to treats a flowrate of 20,000 m/day. The practical limits of removal can be assumed to be 30 mg/L of CaCO3 and 10 mg/L of Mg(OH)2 expressed as CACO3. Assume excess lime of 35 mg/L CaO. Find the following:

Calculate the porosity
Note: Read the question carefully and give me right solution according to the question. I want clear solution with clear steps. A 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.
