Local Authority

In the field of municipal wastewater technology, we offer products and processes for the mixing and treatment of consumable chemicals, patented mixers for flocculation and conditioning of sewage sludge, as well as measurement and laboratory technology for the evaluation of dewatering.


The separation tasks in industrial applications are usually highly specific and usually require a deep understanding of the overall process. In direct dialog with you, we find or develop process solutions specially adapted to them.


Slurry and digestate contain valuable nutrients as well as a lot of water. That’s why solutions for processing and utilization are in demand. We are your contact for slurry and digestate treatment and nutrient separation.
