An asymmetric nanofiltration membrane (Hoechst, PES5) has been characterised by three
different techniques: modelling of the rejection of simple salts, modelling of the rejection of …

Amidst growing environmental awareness and stringent discharge regulations, chemical
and allied process industries are now desperately seeking replacement of the conventional …

Nanofiltration (NF) membranes possess the intermediate molecular weight cut-off between
reverse osmosis membranes and ultrafiltration membranes, and also have rejection to …

Membranes are widely used for separation of ions from a mixture in aqueous solution. Major
applications include removal of sulfate from seawater, removal of salt from cheese whey …

The zeta potential along the surface and through the pores of a commercial nanofiltration
membrane was studied with several electrolyte solutions (including monovalent and divalent …

Based on high quality surgery and scientific data, scientists and surgeons are committed to
protecting patients as well as healthcare staff and hereby provide this Guidance to address …

Two tight nanofiltration membranes of 100 and 400 Da were tested at different operating
conditions. The results show that the selective properties of nanofiltration membranes come …

Concentration polarization is intrinsically associated with the selective character of
membranes and often means flux decline and which causes a subsequent decrease of …

The state of water in the active layer of a series of cellulose acetate asymmetric membranes,
prepared by the phase inversion process, was investigated using attenuated total reflection …

Predictive reverse osmosis (RO) models have been well-developed for many systems.
However, the applications to dilute organic− water systems require the modification of …
