IMPROVEMENT OF THE SCHEME OF THE TECHNOLOGICAL PROCESS OF WATER PREPARATION TO REDUCE THE RISK INDICATORS OF HUMAN HEALTH HAZARD
Currently, there is an acute problem of pollution of surface water bodies. At the same time, the existing sewage treatment plants, their technologies for purifying drinking water do not meet the requirements of the level of safety indicators. The influence of a number of factors on the residual content of aluminum compounds in purified drinking water has been studied. It has been established that such indicators as: pH value, initial concentration of coagulant, concentration of suspended substances, hydrodynamic mode of operation of the cleaning equipment affect the residual concentration of aluminum. The advanced scheme of the water preparation process, which will allow to reduce the residual content of aluminum, is offered. The magnitude of the risk to human health when consuming water containing aluminum compounds for 5-70 years is calculated.
