The Busy Town drinking water treatment plant recently changed coagulant aid from alum to ferrous sulfate (FeSO4·7H2O) for TSS removal. The raw water contains 7 mg/L of TSS. Ferrous sulfate coagulation proceeds as follows: FeSO4·7H2O + 2 Ca(HCO3-) + 1⁄2O2 -> 2Fe(OH)3 (s) ↓ + 2CaSO4 + 13H2O If an optimum dose of 30 mg/L of ferrous sulfate is required to remove 90% of the TSS, calculate the mass of residuals (mg/L) generated in this process.
