An industrial facility discharges a waste that contains 130 mg/L hydrochloric acid at a rate of 12 L/min. The waste must be neutralized with hydrated lime (Ca(OH)2). a. Calculate the amount (kg/d) of hydrated lime required to neutralize the waste. b. Calculate the total dissolved solids (TDS) after neutralization (mg/L). Note: the TDS is the concentration of the solids, in this case CaCl2, formed in mg/L.
