Studies on Synthesis of TFC-RO Membranes and their Applications in Water Industry

Water for drinking, other domestic and industrial purposes needs to be treated according to the purity required. Advanced technologies such as reverse osmosis attains importance in this regard. The development and use of thin film composite (TFC) aromatic polyamide membranes has made membrane technologies more effective and commercially applicable. Even though, the state of the art membrane technologies have many shortcomings including the insufficient salt rejection, insufficient permeate flux.

In the present study effort is made to improve the overall efficiency of commercially available TFC - RO membranes. It aims to synthesize a new membrane with improved efficiency, with the help of commercially available technologies. It also considers the testing the efficiency of the improved membrane. The study will also extend to the application of the membrane in water treatment industry. The membrane so synthesized donot cause any wastage of water and also it is environmental friendly. Thus the newly manufactured membranes could be used for the betterment of water treatment scenario in the industrial sector as well as in domestic usage, as a green technology.
