Countercurrent electrophoretic water purification from ionic and electrically charged colloidal admixtures

Research output


As an alternative to the ion-exchange deionization, the new membrane method of fine water purification from electrically charged admixtures based on countercurrent electrophoresis has been suggested. The countercurrent electrophoresis was carried out in the galvanic mode providing a constant rate of ions transfer in a water flow filtered through a porous membrane. The rate of electrophoretic transfer of ions in the membrane pores exceeds the rate of their movement with a hydrodynamic flow. The experimental data on the water impurity composition given by the proposed method confirmed the theoretical assumptions. Being prepared by the suggested method, water is free from soluble organic admixtures that can appear during the ion-exchange deionization and, with relation to the content of inorganic admixtures, is comparable with and even better than water subjected to ion-exchange deionization.
