Removal of Iron and Manganese Brochure

Groundwater often contains soluble ferrous and manganous compounds which, when getting in contact with air, oxidize and convert into insoluble compounds (oxides, hydroxides). These may disturb processes such as repercolation by choking up infiltration wells, or interfere with other conditioning or treatment processes.

After passage through the filter, the water is practically free of iron and manganese. Differential manometers are used to measure the pressure in the filters.
