The authors show low cost methods of multifold reduction in the consumption of “fresh” water for production purposes, and, accordingly, the amount of wastewater discharged into treatment facilities, as well as ways to substantially reduce the amount of wastewater generated in the process tanks at galvanic and painting facilities. Methods for extracting heavy metals from electrolyte collection and product rinse tanks using internal and external electrolysis and submersible electrochemical modules (SEM) are described. Ways of reducing the amounts of used process solutions (UPS) and wastewater discharged into treatment facilities are presented. The results of studies on compositions of used process solutions are described; they are used to classify UPS by their properties. This classification allows for the use of UPS instead of or in conjunction with the purchased reagents. The practice has shown a substantial reduction in the amount of purchased reagents needed for the operation of wastewater treatment plants at BEMP facilities engaged in the production of protective coatings and printed circuit boards. The rational formation of wastewater streams in the point of their generation ensures effective wastewater treatment using both traditional methods and “associated” technologies developed by the authors. The introduction of “associated” technologies allows for a manifold reduction in the secondary pollution of wastewater and, accordingly, a reduction in the amount of sludge generated in the process.</p>}, number={1}, journal={Real estate: economics, management}, author={Uretski, Yauheni Aronowich and Gogina, Elena Sergeevna and Mоroz Uladzimir Valentinovich}, year={2022}, month={Mar.}, pages={68–75} }
