Iron and Manganese Removal
Most iron and manganese removal treatment processes incorporate oxida-tion to convert the dissolved forms of the metals to a solid, followed by a filtration process. When concentrations in the source water are above 8 to 10 mg/L combined iron and manganese, a clarification step is typically required prior to filtration.
