Almost 100 million m³ of production waste water from BASF is purified here annually. The plant also purifies another 20 million m³ of waste water from the cities of Ludwigshafen and Frankental, as well as from the Bobenheim-Roxheim municipality.
The core of the plant is biological purification: Billions of bacteria transform polluting agents into sewage sludge, carbon dioxide and water. In order to reduce unpleasant smells as much as possible, the biological pools are covered.
The environmental center monitors the inlet and outlet of the wastewater. If there is material in the inlet which would damage the operation of the wastewater e treatment plant, the environmental center diverts the polluted water to a reservoir pool where it is specially treated.
The plant can dispose of over 400,000 tonnes of sewage sludge annually.
