Abstract

Heterogeneous ion exchange membranes were coated with hydrophilic charged layers. The cation exchange membrane was coated with polyvinylalcohol, crosslinked by a reactive dye containing sulfonic groups. The anion exchange membrane was coated by ground anion exchange particles embedded in polyvinlalcohol crosslinked by hexamethoxymethylmelamin. The coating substantially decreased polarisation on both types of membranes. Suppression of water splitting increased the current efficiency at low salt concentrations. In the concentration range of industrial water production, output and energy consumption of the modified heterogeneous membranes is equal to that of highly permselective homogeneous ones. The improvement of the heterogeneous membranes by the coating is due to suppression of polarization. The polyethylene based membranes are heat sealable.
