Biofouling Reduction in Reverse Osmosis Membrane for the Purification Brackish Water, M.Sc. Thesis Sharif University of Technology ; Soltanieh, Mohammad (Supervisor) ; Mousavi, Abbas (Supervisor)
Abstract
In this project, modification of reverse osmosis membrane was investigated in order to reduce the biofouling in treatment of brackish water. Furthermore, the technique which is used to attain the favorable results is graft polymerization to modify the membrane’s surface with grafting acrylic acid as hydrophilic monomer onto polyamide exploited as last layer in reverse osmosis membrane. This technique is a free radical grafting, andfree radicals which are needed for grafting are provided by the redox system potassium persulfate-sodium metabisulfite which was used as initiator. To figure out the best concentration of acrylic acid, initiator and process time in order to achieve a new membrane...
