Our standardized AQUAMAX ® PROFESSIONAL plant series: Wastewater treatment plants for trade, industry, tourism and municipalities

A particular challenge for wastewater treatment plants is the wastewater from commercial or industrial operations: Whether food industry, tourism industry, nursing homes or hospitals - here we often have to deal with irregular wastewater generation and thus strongly fluctuating wastewater volumes. Our experts have already planned and implemented a large number of individual wastewater treatment plants for hotels, restaurants, campsites and other tourist facilities. Of course, our wastewater treatment plants are at least as well suited for municipalities and cities. You can find more details on special application areas in the menu of our solutions by industry.

For aeration, decantation and homogenization of wastewater, we use high-quality surface or submerged aerators, as well as mixers and decanters, depending on the application and suitability. Often we also offer compressors with membrane aeration systems. A large part of our equipment can of course also be rented!

We will be pleased to work out your customized solution and look forward to your inquiry. Please contact us.

Trust in our experience. We have been building wastewater treatment plants of the AQUAMAX ® PRO series for more than 20 years.

By the way: We do not only treat wastewater. Our treatment plants also produce, among other things, your service water for irrigation, cleaning of roads and sidewalks or as cooling water for production processes.
