Question: A jar test has been performed on a water sample for coagulation. The optimal pH is 8, and the 124.2 optimal alum dose is 30

A jar test has been performed on a water sample for coagulation. The optimal pH is 8, and the 124.2 optimal alum dose is 30 mg/L (as alum). The design flow rate is 2 MGD. a. What is the mechanism of coagulation? 6 -S m (MART ())

b. Hw much alkalinity will be consumed at this dose, in mg/L as CaCO3?

C. How much alum is required, in kg/day?
