Development of Scaling Reagent for Waters of Different Mineralization

Membrane technologies are widely used for desalination of water. These technologies are environmentally friendly, economical, energy efficient and material efficient. In the absence of pre-treatment of water, the membrane is contaminated, which leads to an increase in the amount of concentrate formation. Discharge of mineralized water leads to physical and chemical pollution of water bodies. Dissolution and removal of these sediments is a complex issue, so the use of sediment inhibitors is important. The use of antiscalants allows to prolong the service life of membrane elements, which, in turn, will reduce the intake of fresh water and reduce the volume of wastewater. The efficiency of gipan as a reagent in the stabilization treatment of low-mineralized, highly mineralized waters at a temperature of 60°C was determined. The dependences of water stability on sediments on the chemical composition of water, inhibitor concentration and time of ultrasonic treatment of gipan were established.
