Harbauer - Removal of Iron and Manganese
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 reseepage 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. When the latters` charge of ferrous and mangänous compounds reaches a certain limit, a freely programmable process control system initiates the backwashinprocess. While one filter is backwashed, the water is passed through a se cond filter.
The solids-containing backwash water is then thickened by means of flocculating agents. The resul¬ting sludge is dehydrated in a chamber press and disposed of in compliance with the relevant en¬vironmental, protection legislation.
