Biological treatment-ECOPOLYMER

Biological treatment

Implementation geography of ECOPOLYMER in the field of biological treatment includes more than 15 countries. Work package starting from aeration system implementation and finishing with complete reconstruction of biological WWTPs applying up-to-date technologies. Our aeration systems have been implemented at more than 700 plants, including WWTPs of practically all CIS capitals and so as the other cities.

Preliminary clarifier has been reconstructed by installation of mechanical mixers in order to serve as a mixing basin.

Due to the reconstruction of WWTP treated wastewater quality meets the requirements of fishery ponds. More detailed information regarding the works carried out at this plant you can receive from publications.
