Determine the mass of lime and soda ash that need to be added into the raw water each day for water softening. The flow rate of the raw water is 5 MGD. The 35 mg/L excess lime needs to be added. Assuming that the CaCO3 and Mg(OH)2 remaining in the softened water have the equivalent concentration of 30 and 10 mg/L in CaCO3, respectively.
