Our most popular and in-demand product is the block-modular stations of the Biocomplex (BK) series, which are installations for complete biological treatment of household wastewater and industrial wastewater equivalent to them in terms of composition from shift camps, tourist bases and other facilities located far from the central sewer system. BC stations consist of easy-to-install modules, which contain everything necessary for wastewater treatment. The quality of the treated water meets the standards for the discharge of treated waters into fisheries reservoirs, terrain and reuse.
