The environmental and economic efficiency of wastewater treatment by the electrocoagulation method was studied. It has been established that the most widely used are traditional chemical methods, which have certain disadvantages: insufficient cleaning efficiency (fat does not exceed 85-87%, i.e., the residual content exceeds the permitted 50 mg/m3); the danger of secondary contamination with anions (sulfates, chlorides); the formed sludge needs further processing (dewatering and compaction); the danger of personnel working with chemicals. It has been proven that the use of electrochemical methods, namely, electrocoagulation, is justified in order to increase the environmental safety of wastewater treatment processes of dairies. When applied, it becomes possible to create compact water treatment facilities and significantly reduce construction costs. Thanks to the high degree of removal of fats by 98-99% and other pollutants (suspended substances, biogenic elements), favorable conditions appear for discharge to centralized water drainage systems or biological treatment facilities and, accordingly, a significant environmental protection effect is ensured. The dependence of the effectiveness of wastewater treatment by chemical and electrochemical methods on the pH of the medium, the chemical nature of the added reagents, the processing time, and chemical-technological parameters has been established. Rational chemical-technological parameters of electrocoagulation wastewater treatment to achieve the maximum degree of purification from fats and suspended substances with minimum consumption of electricity have been determined. At the same time, it was established that the purified water has a chemical composition that allows it to be discharged into centralized drainage systems or at a biological treatment station.
