Electrical double layer expansion (CDLE) has been proposed as a promising alternative to reverse electrodialysis (RED) and pressure retarded osmosis (PRO) processes for extracting osmotic power generated by the salinity difference between freshwater and seawater. The performance of the CDLE process is sensitive to the configuration of porous electrodes and operation parameters for ion extractio...

Positively charged (cetylpyridinium chloride), negatively (sodium dodecyl sulfate), and non-charged (polyethylene glycol) surfactants are used as potential foulant in reverse electrodialysis systems supplying seawater river freshwater. Fouling tendency of the foulants to ion-exchange membranes is investigated terms adsorption by electromigration, electrostatic attraction, macromolecule interact...

Endosulfan (ES) is a micropollutant found in reverse osmosis concentrates from water reuse applications. Electrodialysis (ED) can remove and recover charged solutes from such concentrates. While polar compounds cannot normally be removed, their fate in ED is important as they can contribute to membrane fouling/poisoning and be released during cleaning. High adsorption of ES to ED membranes was ...

The concentration of orotic acid in dry whey ranged between 64 and 146 mg/100 g and appeared dependent on whey type. The orotic acid of modified whey products, prepared commercially by electrodialysis, ultrafiltration, gel filtration, or polyphosphate precipitation was between 7 and 124 mg/100 g, which was less than that of dry whey. It appears that whey processing methods do not concentrate or...

C. F. MILLS I956 3. The organic complexes of copper in these extracts appeared to be stable in the presence of a cation-exchange resin after in vitro incubation at pH values above 2-5. Below pH 2-0 decomposition of complexes was appreciable. I wish to thank Dr J. Duckworth for his interest and encouragement and Dr R. L. M. Synge for advice on electrodialysis techniques. Thanks are due to Miss G...

14 The mechanisms of sorption of four steroidal hormones – estradiol, estrone, progesterone and 15 testosterone – to electrodialysis (ED) membranes were investigated as a function of solution pH 16 and presence of humic acid (HA). Hormone-membrane partition coefficients (log KAEM/CEM) 17 determined through sorption isotherm experiments suggested that hormone sorption was due to 18 hydrogen bond...
