The objects of the study - solutions of electrolytes, dilute and concentrated disperse systems. The purpose of the work is to conduct basic research aimed at studying the regularities of transport of particles and ions in hydrodynamic and electric fields in application to the problems of water desalination and dehydration of dispersions. Research methods - methods of analytical chemistry, electrochemistry and mathematical physics. The influence of porous charged impurities on the rate and degree of dehydration of clay dispersions using pressure and electric field was studied. The conditions of using polymeric flocculants and electrolytes for sedimentation and consolidation of particles in the preparation of highly diluted dispersions for dehydration have been studied. An experimental study of the transfer through the ion exchange membranes of single- and double-charged cations in the stationary and pulsed mode of operation of the electrodialyzer at different frequencies, voltages, concentrations of dissolved electrolyte and its flow rates through the desalination chamber was performed. The influence of minerals and physical fields on water quality has been studied.
