A new group of asymmetric non-cellulosic membranes having a performance intermediate between that of a conventional RO membrane and an ultrafilter has been developed. Its main characteristics are high fluxes (4-IO m 3/m 2 day) at low pressures (6-10 at) and moderate rejections for various salts . Fr
A new reverse osmosis membrane composed of the following aromatic polymer containing benzimidazolone ring was studied. ## (PBIL) Lonsdale's permeability parameters of PBIL (e.g., PI/P, = 21.3 x IO3 g/cm3) show its excellent potential as permselective membrane material. Asymmetric membranes were s
The chaxged metimes were prepared from the s~onation and an&&ion of SBR resins, and their reverse osmosis performances were investiiated. The sulfonated membranes show high salt rejection. This result is in accord with the result of membrane potentials. Relatively excelIent membranes were ohtained b
Small colloidal particles intermediate in size between suspended solids, and true dissolved solids have been causing serious problems to many reverse osmosis systems throughout the world, These tiny negatively charged particles become concentrated at the surface of the membrane during the R-Oprocess
