Abstract
Ground water containing ferrous compounds is first treated with aluminum sulfate before aeration followed by lime addition after aeration to produce an iron-aluminum sludge possessing an oxidative capacity. Portions of the sludge are recycled back to utilize the oxidative capacity of the sludge. Chlorine is added after the oxidative capacity of the sludge has been utilized. An improved oxidation and removal of iron is obtained, yielding a treated water low in iron content with decreased requirements for chlorine.
