ABSTRACT:
A process for removing aluminum and sulfate values from an aqueous solution containing the same which comprises passing the solution through a semi-permeable membrane in a pressure vessel. The permeate solution is depleted of aluminum and sulfate ions and the concentrate solution is concentrated in aluminum and sulfate ions. The concentrate solution can be re-used in alum manufacture and the permeate solution can be discharged into public waterways without further purification.
