The basic reaction involved in the precipitation of phosphorus with aluminium is: Al3+ + HnPO43-n Liquid alum [Al2(SO4)3 .18H2O] contains 48 % aluminium and based on laboratory testing, 1.5 moles of aluminium react with one mole of phosphorous (P). Given a liquid alum of density 1.2 kg/L and a flow rate of 12 000 m/day, determine the: - AIPO4 + nH*. a) Amount of liquid alum required to precipitate phosphorus in wastewater that contains 8 mg P/liter. b) Required alum storage capacity if a 30 day supply is to be stored at the treatment facility.
