A proposed continuous flow process for the removal of iron and manganese found in many water supplies have been investigated. The basic process consists of oxidation of the iron and manganese by sodium hypochlorite and subsequent removal of the oxidized particles through standard cartridge filter. Several variations in the basic process have been employed in an attempt to improve the filterability of the oxidized particles. Some characteristics of the resulting filter cake have been determined. Substantial improvement has been attained through the addition of body feed prior to filtration. (Author)
