Abstract The use of ferrous sulfate for precipitating phosphate from water was investigated. Different phosphate containing solutions were evaluated: (1) pure orthophosphate, (2) secondary effluent from a waste treatment plant, and (3) precipitation of phosphate in a simulated activated sludge process. It was found that ferrous sulfate should be very effective for removing phosphate in the activated sludge process. The low dissolved oxygen concentration will control the oxidation of ferrous iron to optimal rates, and the sludge will increase the settling rate of the phosphate precipitate. (Author)
