Question

The surface water from Santa Claus, In is being pumped at 200 m3/min to serve the city and has an alkalinity of 70 mg/L CaCO3. The treatment plant uses an alum concentration of 20 mg/L to reduce the turbidity of the water Determine the total alkalinity consumed (mg/L CaCO3). Is the amount of alkalinity consumed more than the initial concentration of alkalinity in the water, explain? Al2(S04)3* 14H2O + 6HCO3' = 2Al(OH)3(s) + 6CO2 +14 H2O + 3SO4 2- Hint to gel CaCO3 concentration: mg/L CaCO3 = mg/L species * (EW CaCO3/EW of species)
