Achieving Higher Flow Rates And Smaller System Footprints For Iron Removal With Manganese Dioxide Filter Media

By Gerry Bulfin

Traditional processes used to remove iron and manganese from groundwater have commonly included oxidation with chlorine followed by a filter with sand or other media.

The filter media typically used to remove iron after oxidation include a mixed media of filter sands and anthracite; or filter media such as silica or greensand that are coated with a layer of manganese, or a special type of high purity manganese dioxide ore.
