Feldhofe mud dump site, Germany

The Project:


To treat the surface discharge water before it enters the receiving water course.


Executing company:

Firma PLA Pumpen und Anlagenbau GmbH

22844 Norderstedt


The problem:


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.


The solution:


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.

In the event of abrasive and corrosive utilization, stronger wear and tear will take place naturally in certain components. With regards to the above application wear and tear can take place mainly in impeller, agitator, suction plate, shaft sleeve, oil ring, mechanical seal, pump casing, strainer, motor casing and discharge coupling. Depending on the working conditions the lifetime of those parts might vary significantly and can be shorter than the legal warranty period.
In this regard, please pay attention to our general terms and conditions that we also send to you by mail on request.
