Incoming water contains 2.5 mg/L as a substance of natural alkalinity (HCO3-). The flow rate is 9.5 ML/day).
(a) What feed rate is required if the alum dose is 7 mg/L and is available with 87% purity.
(b) What is the annual cost of alum if it is available at $234 per Megagram (Mg).
Ans:
(a) Given that purity, P = 87% = 0.87
(b) Annual quantity cost of alum
Amount of alum needed per year = 76.4 Kg/day *365 day/year
= 27886 Kg/year = 27.886 Mg/year {1000 kg = 1 Mg)
Alum cost = 27.886*$234 = $6,525/year.
