The water protection association of the region Zugersee-Küssnachtersee-Ägerisee (GVRZ) operates the wastewater treatment plant (WWT) Schönau and had to upgrade the WWT with a treatment stage for the elimination of micropollutants (EMP) in order to comply with the legal requirements. For this purpose, the process combination with the dosing of powdered activated carbon (PAC) to the filtration stage with the possibility of direct dosing into the biological stage was selected as the most suitable process variant.

SÜLZLE KOPF supplied, assembled and commissioned the complete mechanical equipment for the process evaluated for the elimination of micropollutants in the form of AK-DOS®.
