2.4 One method of removing phosphate from wastewater effluents is to pre-cipitate it with aluminum sulfate (alum). A plausible stoichiometry (butnot exact because aluminum and phosphate can form many differentchemical materials) is:2 PO³ + Al₂(SO4)3 2 AIPO4 + 3 SO4²-If the concentration of phosphate (PO) is 30 mg/L, how many kg ofalum must be purchased annually to treat 40 L/s of wastewater? Howmany kg/yr of solid precipitate will be formed (dry basis) if all of thephosphate is precipitated as AIPO₂?
