WATER TREATMENT AND DEMINERALIZATION TECHNOLOGY STREAMLINING FLOW CHARTS FOR TREATMENT OF METAL-CONTAINING MULTICOMPONENT WASTEWATERS AT INDUSTRIAL ENTERPRISES

摘要

The paper demonstrates that at the modern stage of industrial development metal-containing wastewaters are multicomponent, resulting in serious difficulties in applying the existing technologies of their purification. The paper analyzes the composition of wastewaters as well as the most common processes and flow charts for their purification. The paper recommends basic facilities and the range of application of various flow charts for metal-containing multicomponent wastewater treatment.
