Abstract


Вackground. The development of a method for increasing the efficiency of an installation for electrochemical water disinfection.

Оbjective. The aim of the paper is the study of the influence of electrokinetic phenomena on the mass transfer in a system with a charged porous diaphragm, aimed at determining the conditions that allow increasing the efficiency of the process of electrofiltration water disinfection while maintaining the parameters of its conduct and ensuring the necessary degree of decontamination.

Methods. The determination of the efficiency of the microporous filter element in various ways of organizing the electrofiltration process is conducted.

Results. The efficiency of the microporous charged element depends on the location of the cathode and the anode, which determines the direction of the electroosmosis with respect to the flow of the treated water. Increasing the strength of the electric field while maintaining the value of the operating pressure leads to an intensification of the processes affecting the efficiency.

Conclusions. The location of electrodes, which ensures the counter motion of the hydrodynamic flow of the treated water and the electroosmotic flow occurring in the pores of the charged diaphragm, allows substantially increasing the productivity of the disinfection process.
