Water simply comes out of the tap, and disappears again as easily. Or so you think. But water is not a disposable product – the wastewater of today is the drinking water of tomorrow. For this cycle to function sustainably, conscious and non-wasteful use of water resources is required, as is the safe functioning of the wastewater purification system, reliably removing pollutants in an environmentally friendly manner. Wastewater management is a basic public service and environmental protection in one.
Modern wastewater treatment takes place in a series of stages that are carefully coordinated with one another. The wastewater treatment process begins with the mechanical purification, followed by biological purification and final clarification. At the end there is the treatment of the sewage sludge produced. This is simultaneously the interface to the next process, sewage sludge recycling.
Wastewater technology = "high-tech"
The days in which wastewater treatment plants consisted of nothing but tanks for mechanical purification are long gone. The biological purification stage for breaking down carbon, phosphorus and nitrogen became standard in our plants at an early stage. With the first trial operations for membrane filter technology, we are taking the next step towards the use of state-of-the-art technology for the process of wastewater treatment.
As a future-oriented regional stakeholder in the water management sector, we are continuously searching for innovative solutions for a wide range of challenges. We participate in a whole series of projects to develop promising new concepts, not only for wastewater treatment, but also for energy generation, and for coping with a changing climate, both at a state level and on a European scale.
