Despite global problems that can affect the world economy (COVID-19, military conflicts, migration, etc.), the world's manufacturing capacity continues to grow. Inefficient water usage production schemes, an unacceptable state of water treatment facilities, outdated material-hungry wastewater processing methods lead to the worsening of Ukraine's ecological situation. Electroplating manufacturing is among the biggest industrial water consumers. One of the most dangerous contaminant is chromium electroplating line. Hexavalent chromium compounds are classified as Category 1 health hazard. Among numerous methods for treatment of chromium-containing electroplating waters the electrochemical method was chosen as the most appropriate. A fundamentally new technological scheme for the treatment of wastewater of chromium electroplating manufacturing line, with the underlying principle of creating closed-circuit resource circulation was developed. The design of the electrocoagulator was improved by equipping with special floatation device that helps to prevent the formation of channels and cavities in the near anode. The ectrofloatocoagulator, which combines galvanic and electrochemical dissolution of anode and floatation was tested. The generalized schematic of the advanced electrochemical process was showed. The proposed scheme includes electrocoagulation and flotation technologies and allows for water treatment down to regulated values with minimal power consumption, while output mud sludge with stable structural characteristics. Laboratory analysis of obtained precipitate samples, allowed to conclude that based on chemical inertness of layered double hide oxides, they can be used as landfill material, secondary raw materials: pellets in metallurgy, ceramic tiles, bricks, etc.
