Chlorination-Filtration for Iron and Manganese Removal
Author: Joseph M. Wong
Date: 1/184
Reprinted from the Journal AWWA Research and Technology, January 1984

Processes in which oxidation is followed by removal of suspended solids can effectively remove soluble iron and manganese from water. Three common processes for removing iron and manganese are: (1) aeration-filtration, (2) chlorination-filtration, and (3) potassium permanganate-manganese greensand filtration. This article describes these processes and presents results from a pilot study of chlorination-filtration. The costs for oxidants in chlorination-filtration are less than those for potassium permanganate-manganese greensand filtration.
