Unique treatment facilities of the TANECO Complex
The TANECO Complex was the first in Russia to build and operate unique treatment facilities using membrane treatment technologies that provide the possibility of returning up to 80% of treated effluents to production subject to receipt and deep treatment of all generated effluents — industrial, domestic, storm. The efficiency of wastewater treatment for some substances is up to 99.9%. It allows to reduce the content of pollutants in effluents to the required maximum permissible concentrations for fishery reservoirs.
