Abstract

The invention relates to processes for membrane regeneration, in particular baromembranes. The process for baromembrane regenerative processing includes the consecutive processing of membranes under the pressure of 30 kg/cm2 with solutions of catholyte with pH 9,0à10,0 and of anolyte with pH 5,0à6,5, obtained by electrolysis of the sodium chloride aqueous solution of 0,1à0,5% into a diaphragm cell, at a current density of 1à3 A/dm2 and subsequent washing with water.
