IN316694: Thin film composite reverse osmosis membrane with antifouling properties and method of preparation of the same

Acces sibility Controls

The invention relates to the preparation of Thin Film Composite (TFC) Reverse Osmosis (RO) membranes with novel composition of monomers for water desalination. More particularly, the invention relates to the preparation of TFC RO membranes by interfacial polymerization between neat 2,4,6-Pyridinetricarboxylic acid Chloride (PTC) or mixtures of PTC and Trimesoyl Chloride (TMC) with M-Phenylenediamine (MPD) on the surface of porous polysulfone support. The developed membranes exhibit NaCI rejections of 94 +/- 1% with 50-55 litres/m2h product water rates when tested under brackish water desalination conditions.
