CS6 - Altenrhein (Switzerland)

CS6 - Altenrhein (Switzerland)

The wastewater treatment plant (WWTP) of Altenrhein is located in the eastern part of Switzerland and has a regional responsibility for sewage sludge management. The technology of the WWTP consists of primary sedimentation, bio-filtration and activated sludge reactor in parallel, digestion, sludge dewatering and drying of self-produced and received sludge.
In this case study, the innovative membrane system for ammonia (NH3) stripping will be tested and evaluated in a large-scale unit, thus moving beyond state-of-the-art in physical nitrogen treatment of sludge liquid while recovering a valuable fertilizer.
