Question

Determine the amount of CO2 generated in kg/day for a coagulation dosage of 120 mg/L of
Al2(SO4)3.14 H2O in a WTP of capacity 20 MLD. Assume any data if required.​

Answer 1

Explanation:

Polyelectrolyte.

Dosing rate (design) 0,2 mg/l.

(0,2 mg /l x 720.300 m3/d) / 1000 144 Kg/d.

Solution 0,2 %

Flow rate = 144 / (0,002 x 1.000) = 72 m3/d 3.000 l/h.

Metering pumps 8 + 3.

Capacity of each pump 400 l/h.

Pump range capacity 50 - 500 l/h.
