Interpolymer and heterogeneous membranes have been synthesized and pilot tests of the designed electrodialysis and reverse osmosis units for the treatment of waste waters of Pavlodar Petrochemical Plant LLP have been carried out. A hybrid process flowsheet for industrial waste water treatment has been developed and a comparative efficiency analysis of the electrodialysis and reverse osmosis processes by the depth of treatment and demineralization has been performed.
