A polymeric membrane of interpenetrating network of polyurethane urea and poly (methyl methacrylate) (PUU-PH MA] comprising PI4MA in the membrane composition hi the range of 5 to 50% preferably S to 27%, specific gravity In the range of 1.5 to 15 preferably 1.6 to 1.8 and thickness in the range of 50 to 500 preferably 150 to 400 micron. The membrane of the invention would provide fir an effective means and a process whereby contamination of natural water with organic pollutants In particular chlorinated compound such as, p-chlorophenol and 2,4 di-chlorophenol could be simply and effectively removed. Also disclosed is a process for removal of p-chlorophenol and 2,4 dichlorophenol and systems for use in batch or continuous separation of the p-chlorophenol and 2,4 dichlorophenol to thereby take care of the environmental hazards / concerns due to contamination of natural water with such organic pollutants mainly due to discharge of Industrial effluents.
