perform design calculations for a 10MGD raw water supply. the supply has 20 mg/l of natural alkalinity and requires 50 mg/l Alum for effective coagulation In addition a residual alkalinity of 5 mg/l is required in the treated water.
a. How much alkalinity must be added? (mg/l) and (kg/d)
b.size the lime tank to hold a 90 day supply if alkalinity is to be supplied as
i)liquid lime. (kg/d) and (m^3/d) and required tank size (m^3)
ii)67% pure quicklime powder CaO.(kg/d) and (m^3/d) and required tank size (m^3)
