Effect of Organoclay on the Performance of Reverse Osmosis Membrane
This study investigated the effect of Cloisite15A (C15A) organoclay in the substrate layer on the performance of reverse osmosis (RO) membranes. The substrate of the RO membranes was modified using different loading of C15A (ranging from 0.3 - 0.7 wt%) within polysulfone (PSf) substrate and the polyamide (PA) selective layer was formed on the top. Effect of the modified substrate layer on the water flux and salt rejection of the nanocomposite membrane was investigated. The chemical property, morphology, and topography of the membrane surface were characterized by ATR-FTIR, SEM, AFM and contact angle analyzer. The modified membranes showed significantly enhanced pure water flux and salt solution permeability by 60.5 % and 44.3 %, respectively, without sacrificing the salt rejection.
期刊介绍：
The Journal of Membrane Science and Research (JMSR) is an Open Access journal with Free of Charge publication policy, which provides a focal point for academic and industrial chemical and polymer engineers, chemists, materials scientists, and membranologists working on both membranes and membrane processes, particularly for four major sectors, including Energy, Water, Environment and Food. The journal publishes original research and reviews on membranes (organic, inorganic, liquid and etc.) and membrane processes (MF, UF, NF, RO, ED, Dialysis, MD, PV, CDI, FO, GP, VP and etc.), membrane formation/structure/performance, fouling, module/process design, and processes/applications in various areas. Primary emphasis is on structure, function, and performance of essentially non-biological membranes.
