  • An overview of reverse osmosis

    Reverse osmosis is the separation or filtration method by which many types of molecules and ion particles are removed from the solution through porous membrane-technology filtration. Reverse osmosis systems work very well at removing all types of hard minerals and contaminants in the water. Hard water minerals are easily removed from the reverse osmosis membrane. An amount of pressure is applied ...

  • Surface modification of reverse osmosis membranes with zwitterionic polymer to reduce biofouling

    The zwitterionic homopolymer poly[2-(methacryloyloxy)ethyl-dimethyl-(3-sulfopropyl) ammonium hydroxide was coated onto the surface of commercial polyamide reverse osmosis (RO) membranes. Aqueous solutions of the polymer at different concentrations were applied to modify the polyamide membranes through an in situ surface coating procedure. After membrane modification, cross-flow filtration ...
