Water Decontamination of Charged Dispersed Particles in Electrofilter with Conducting Bed

Abstract

Electrofiltration of the particles of cation exchanger KU-2-8 and anion exchanger AV-17 pounded to the size (1–4) μm through a granulated cation exchanger KU-2-8 was investigated. The interval of electric field strength and flow velocities of a filtered liquid, which achieves a stable 99% degree of decontamination, is determined. Features of the impact of polarized dispersion particles on their movement in the electric field, aggregation and formation of the sediment on the granules are analyzed. It is shown that the movement of these particles to the granules is done mainly owing to dipolophoresis and the formation of particles aggreagates which form the sediment is caused by the dipole-dipole interaction.
