To treat the surface discharge water before it enters the receiving water course.
Firma PLA Pumpen und Anlagenbau GmbH
The discharge water of the Feldhofe mud dumpsite is heavily laden with Fe-ions. Treatment of the surface discharge water is necessary before it enters the receiving watercourse.
Treatment via oxidation and iron oxide precipitation, assisted by a 2.2kW submersible aerator. Since the bottom of the natural water body is uneven and muddy, a base plate was welded on and the aerator sunk using a crane. Oxygen measurements made after installation (using DO electrodes) were highly satisfactory.
