Title:

Technology for the Manufacturing Thin Film Composite Reverse Osmosis Membrane for Desalination and Water Purification
Value Proposition:

A process for preparation of high flux and salt rejection thin film composite (TFC) reverse osmosis (RO) membrane.
Summary Application:

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.
Advantages:
  • Fabrication of TFC membranes (100x100 m2) with indigenously designed and developed semi-automated polysulphone casting and TFC polyamide coating machines.
  • Cost effective technology for preparation of TFC support membranes and polyamide TFC membranes thereof.
  • Improvement of fouling resistance property of the TFC membranes by simple and robust post treatment method and thus improvement in the membrane life.
  • Improvement of chlorine stability by simple and robust post treatment of the TFC membranes.
