Brief Description

Description :

A modified thin film composite reverse osmosis membrane and a process for preparation thereof. Another object of the present invention is to provide a process for the preparation of low fouling thin film composite (TFC) reverse osmosis (RO) membrane with improved chlorine resistance is provided. It has low fouling, high flux and high rejection thin film composite reverse osmosis membranes at commercial scale levels at the rate of 20-25 m/h using semi-automated machinery.
