Streaming potential

The alumina microfiltration(MF) membrane was modified with nanocrystalline TiO2 in the pore wall. The electrokinetic properties of unmodified and modified alumina membranes were characterized by streaming potential measurements during tangential filtration at various conditions of pH, ionic concentr

Based on the reversible volume phase transition of Poly(N-isopropylacrylamide) (PNIPAAm) around LCST, a simple temperature-change cleaning method for PNIPAAm grafted porous polyethylene membrane fouled by bovine serum albumin (BSA) was proposed. It was found that after the temperature-change cleanin

Streaming potentials (SPs) across a porous membrane in various organic–aqueous solutions have been studied experimentally. The effects of both the solvent (including its species and weight percentage) and the electrolyte (including its species and concentration) on the SP are presented respectively.

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

The present study compares the fouling properties of two selected and well-characterized hydrophobic (denoted HPOA) and hydrophilic (denoted TPIA) natural organic matters (NOM) fractions with a commercial polyamide (PA) nanofiltration (NF) membrane (denoted NF-55). Analytical tools such as elemental

The filtration tests of electrolyte solutions performed with different ceramic membranes show that salt rejection depends on pH, salt nature and concentration. A simple correlation between streaming potential and rejection rates exits and confirms that streaming potential is a relevant parameter to

The streaming potential measured through the wall of a charged ceramic UF membrane is a relevant parameter to predict the retention properties of the considered membrane for ionic solutions. It is more satisfying than the electrophoretic measurement of the material particles used to prepare the memb

A study of the membrane zeta potential determined by the streaming potential was made to investigate the electrokinetic characterization as well as the monitoring for cake deposition on the surfaces of a filtration membrane. The membrane zeta potential related to the surface charge characteristics w

A temperature-sensitive N-isopropylacrylamide (NIPAAm) grafted polyethylene microporous membrane was prepared by the plasma-induced graft polymerization technique. The SEM observed that the poly(N-iso-propylacrylamide) (PNIPAAm) chains grafted on the membrane surface exhibited difference configurati
