An interfacial polymerization process (IFP) for preparing a highly permeable TFC RO membrane by contacting on a porous support membrane for IFP, a polyfunctional acyl halide monomer and a polyamine monomer and recovering a highly permeable thin film (TFC) reverse osmosis (RO) membrane. At least ...
FilmTec™ Reverse Osmosis Membranes FilmTec™ NF membrane elements are designed for process applications where a separation of solutes is desired. l NF is a durable polypiperazine amide membrane designed to reject organics with a molecular weight above 200 while passing monovalent salts. l FilmTec...
How To Clean Reverse Osmosis (RO) Membranes Successful membrane cleaning relies on both the effectiveness of the cleaning compounds, their professional application and the design and operation of the cleaning equipment. For the best results, RO membrane cleaning should be performed with both high and...
Prediction of boron transport through seawater reverse osmosis membranes using solution–diffusion model One of the key transport parameter—permeability, is being used as an intrinsic characteristic of membrane for reverse osmosis process prediction. In this ... PVX Hung,SH Cho,SH Moon - 《Desalinati...
HILLMAN,RAYMOND H. HOROWITZ 被引量: 5 摘要: Reverse-osmosis membranes are prepared by surface acetylation of cellulose film. A pre-treatment consisting of exposure of the film to high relative humidity, prior to acetylation, is employed to provide superior salt rejection....
