Membrane surface charge

Dairy ultrafiltration permeate (UFP) has been filtered using polyamide nanofiltration (NF) membranes in order to separate potentially valuable calcium and lactose from unwanted monovalent salts. An investigation into both the fouling and separation behaviour has been carried out to gather useful inf

The main objective of this work was to study the effect of salt concentration and pH on the surface charge of loose nanofiltration (NF) membranes through streaming potential measurements. A Dow pilot unit equipped with a plate-and-frame module allowed the simultaneous test of two commercial NF membr
