  • Modified thin film composite reverse osmosis membrane and a process for preparation thereof
    Patent number: 10384171
    Abstract: The present invention relates to a complete process for preparation of high flux and salt rejection thin film composite (TFC) reverse osmosis (RO) membrane including process for preparation of support membrane for thin film, process for thin film coating of support membrane by in-situ interfacial polymerization between diamines and trimesoyl chloride, machine design, chemistry and details of process (engineering+chemistry+ambient) parameter at 1×100 sqm scale upgradeable to a scale even 10-20 times higher. The produced membrane is characterized by 96% salt rejection and 48 LM-2H 1 flux with 2000 ppm sodium chloride solution at 250 psi pressure and 95% salt rejection and 46 LM2H 1 flux with 35000 ppm sodium chloride solution at 900 psi pressure. The present invention also relates to complete machine design for PSF ultrafiltration membrane casting and coating for TFC membrane production at commercial level.
