Question
![A water with low alkalinity of 15 mg/L as CaCO3 will be treated with the ferrous sulphate-lime
coagulation. FeSO4 dosage is 18 mg/L.
(CaCO3 = 100 g/mol, Ca(HCO3)2 = 162 g/mol, Ca(OH)2 = 74 g/mol, FeSO4.7H₂O = 278 g/mol,
Fe(OH)2 = 90 g/mol).
a. Determine the lime dosage needed to react with the ferrous sulphate for sweep
coagulation.
b. If dissolved oxygen (DO) concentration is 5 mg/L before coagulation, what is
concentration of DO after coagulation?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F393037b2-7449-4bd7-a188-129f813a1361%2F6c62f796-1307-4e44-b013-f98a167df6f6%2Fjg07vcl_processed.png&w=3840&q=75)
