Construction technology:
The object of the construction is the new construction of WWTP (cleaning capacity of 3 000 EO), partly on the site of the existing WWTP and partly on adjacent land. The technologically is WWTP designed with three-stage cleaning. It is a mechanical-biological sewage treatment plant with nitrification and self-contained pre-classifiable denitrification, with complete aerobic stabilisation of sludge in the cleaning process. A rotary drum filter is designed as a tertiary stage of wastewater treatment.
