Abstract
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.
