Hydraulic rehabilitation of an outflow vane

The treatment plant is fed from two wells with a total of up to 10 m3/h of water. There, the water is first pumped into the input template, where it flows into it in the free overflow. In this case, intensive mixing with atmospheric oxygen is realized. The iron dissolved in the water is oxidized to iron hydroxide and precipitates. The water is purified by the subsequent gravel filter stage, via a pressure increase stage and the iron precipitates are separated off.

The clear water is purified from organic pollutants by means of two activated carbon filters connected in series. A final measurement of the water content by an online gas chromatograph ensures permanent compliance with the limit values. The system runs fully automatically in regular operation. Frost-sensitive plant equipment as well as the fittings are mounted in sea containers.
