ASSESSMENT OF IMPACT OF RECALCULATED WATER PHYSICOCHEMICAL COMPOSITION CHANGE ON PROCESS OF SCALE CONTROL WHILE ELECTROMAGNETIC TREATMENT
Behavior in time of scale-control effect of an electromagnetic water treatment appliance was analyzed. It was found out that the scale-control effect of the electromagnetic water treatment appliance persists to a greater or lesser extent throughout the term of its operation. It was also found out that water hardness, i.e. the extent of recirculated water evaporation, works on the antiscale effect of the appliance, as well as on the electrical conductivity of treated water. The higher the water hardness, the higher the antiscale effect and the more intense is the process of reduction of treated water electrical conductivity. Based on comparison of results of determination of antiscale effect and electrical conductivity behavior with the process of scale control of heat-exchange surfaces it was found out that change of these parameters of treated water has no impact on the sludging process, which continues throughout the term of the electromagnetic water treatment appliance operation.
