Municipal waste water treatment

Due to the development of the catchment area the sewage treatment plant Dresden-Kaditz has reached its capacity limit. In addition, a renewal of the old plant which was altered during ...

The common waste water treatment plant of Oyten/Ottersberg is, besides the municipal charge, also developed for the indirect food purification process.

Energetic optimization

The waste water treatment plant of Dessau-Rosslau offers a good starting point for energy savings.

Waste water discharge

As a result of the expansion of the Frankfurt International Airport, a rain water retention basin was built at the western point of the existing parallel runway system in the area of the entry lanes.

The inner city area of the city of Wilhelmshaven is drained by a mixed-water system, the sub-basins are each assigned to a pumping station. In the event of high rainfall events, the two pumping stations discharge mixed-water, whereby the South pumping station discharges into the

The pumping station left of the hanseWasser GmbH was built between 1975 and 1977 and supports the entire accumulating waste and rain water from the left side of the river Weser by two parallel pressure pipes DN 1000 towards the sewage treatment plant of Seehausen.

The development of the drainage plan for the expansion of the airport was carried out as part of the planning approval procedure, which provides the following drainage system for the runway Northwest:

Purification of industrial waste water

Due to changes in the waste water discharge requirements and increased fees for discharging the waste water into the public sewer system, the InBev decided to build fully biological waste water treatment plants for 5 breweries in Russia.

Operational optimization

The sewage treatment plant of the Erdinger Moos Wastewater Board disposes arising waste water within its area including especially during winter the de-icing waste water form the Franz-Josef-Strauss airport.

Power systems, cogeneration installations

The two CHP-units utilize the biogas from the biogas plant of Hillersee PW III of the Brunswick Wastewater Board, which is 20 km away. Approx. 1,000 m³ of biogas per hour are transported via the 20-km-long biogas network of the BS Energy to the location in Oelper.

The existing combined heat and power unit (CHP) of the sewage treatment plant at Buchenhofen in Wuppertal is a 4-module system, dating from 1998, which has reached the end of scheduled life time.

The Waste Water Treatment Company of State capital Düsseldorf realizes a new combined heat power plant at the sewage treatment plant of Düsseldorf-South.

The existing CHP plant at the sewage treatment plant of the Erdinger Moos Wastewater Board consists of a
3-module system, which has reached after approximately 16 years of operation the end of economic life.
