The objects of the study - solutions of electrolytes, dilute and concentrated disperse systems. The purpose of the work is to carry out fundamental research aimed at studying the regularities of interaction and transport of particles in the electric field in application to solving applied problems of water purification and dehydration of dispersions using electromigration, electroosmosis and electrochemical processes. Methods of research - methods of analytical chemistry, electrochemistry and mathematical physics. Main results: а theoretical and experimental study of the electrical retention of charged disperse impurities on polarized ion exchange materials in an electric field , depending on the sign of the charge of these materials, the intensity of the electric field, the speed of the hydrodynamic flow and the concentration of the background electrolyte are carried out. The literature data are analyzed and optimal methods of influence on surface and coagulation properties of highly dispersed sediments with high humidity are determined. The regularities of recharging, sedimentation and compaction of fine disperse sediments with different chemical composition of electrolyte solutions are established. The electrocatalytic activity of electrodes during oxidation of organic impurities and water disinfection was investigated. The obtained results are important for the development of the fundamental foundations of processes in disperse systems in applying to water and soil treatment technologies. The application area is water treatment.
