TECHNOLOGY OF CAVITATION TREATMENT OF CLARIFYED WATER OF A CLOSED HYDRAULIC ASH-TRANSPORT SYSTEM

Topicality of problem is due to significant pollution of clarified water used for transport of ash and slag waste of Kansk-Achinsk coal combustion. The high concentration level makes impossible discharge or use of wastewater in case of a positive balance. Chemical analysis of clarified water was carried out and pollutant concentrations determined. The method of hydrodynamical cavitation was offered for decrease of pollutants concentrations of clarified water. The water was processed in three modes in the conducted experiment. As a result, was approved that cavitation method lead to significant decrease of carbonate ion and total hardness concentrations.
