“…Over the last decade or so, there is an increasing worldwide interest in the use of IEMs on a large industrial scale in processes such as electrodialysis, electrodeionization, diffusion dialysis, and energy conversion and storage systems [2][3][4][5]. Among them, electrodialysis (ED), in which a series of alternating anion-and cation-exchange membranes arranged between two electrodes, is today one of the most stateof-the-art ion-exchange membrane process.…”

“…[2][3][4] Unfortunately, due to the inherently hydrophobic nature of polymeric membranes, organics, colloids and micro-organisms in feed solutions are prone to adsorb onto membrane surfaces and in pore walls during the operation, leading to membrane fouling. 1 Ultraltration (UF), an emerging membrane technology that utilizes hydraulic pressure to drive water permeation, is the subject of signicant current interest due to its advantages of low energy consumption, high separation efficiency and the absence of any need for chemical pre-preparation.…”

Ultrafiltration (UF) is an emerging membrane-based water separation process with potential application in drinking water treatment and for wastewater reuse. Nevertheless, membrane fouling decreases membrane performance and increases the frequency and cost of chemical cleaning. In this work, we present a method for loading ZnO nanoparticles into a polyethersulfone (PES) UF membrane to improve its fouling resistance.ZnO nanoparticles were synthesized with a sol-gel process using cost-effective precursors, resulting in particles with an average radius of 10 nm and ZnO content between 0.25 and 0.75 wt%. The hydrophilicity of the membrane surface was improved by the integration of ZnO nanoparticles, leading to a reduction in membrane contact angle (75.5 to 62.6 ) and an increase in permeability (46.4 to 365.8 L m À2 h À1 ). Sodium alginate (SA), bovine serum albumin (BSA) and humic acid (HA) were chosen as model organic foulants to investigate fouling behavior of the fabricated membranes. Reduced fouling was conspicuously observed for ZnO/PES composite membranes compared to control membranes in all fouling cases. In order to better understand the fouling mechanism, atomic force microscopy (AFM) was used to quantify the intermolecular adhesion forces between the foulant and the clean or fouled membrane. Lower adhesion forces were observed for the modified membranes, indicating that the addition of sol-gel formed ZnO nanoparticles endows the PES UF membrane with an improved antifouling performance.

“…1,2 Among alternative biofuels, biobutanol (n-butanol), having a higher fuel value, a lower volatility and a lower freezing point compared with ethanol, 3 is expected to play an important role in the next generation of biofuels.

Hyperbranched polysiloxane (HPSiO) was successfully synthesized by a three-step process. The result of 29 Si Nuclear Magnetic Resonance (NMR) measurement indicates that the degree of branching (DB) of HPSiO is 0.73. Then, novel polysiloxane membranes, HPSiO-c-PDMS, were prepared by the cross-linking reaction between HPSiO and a,u-dihydroxypolydimethylsiloxane (H-PDMS) with different molecular weights. HPSiO-c-PDMS membranes were first used as membrane materials for recovering n-butanol from an aqueous solution by pervaporation (PV). The HPSiO-c-PDMS membranes demonstrated high n-butanol/water selectivity as well as high permeability. As the molecular weight of H-PDMS increased, the selectivity increased and the n-butanol permeability of HPSiO-c-PDMS-2 (with moderate H-PDMS molecular weight) membrane showed the highest value. The effects of temperature and feed concentration on the PV performances were also investigated. The PV performance, n-butanol permeability and n-butanol/water selectivity of the HPSiO-c-PDMS-2 membrane, reached 4.3 Â 10 5 Barrer and 8.75, respectively, with a feed concentration of 1.0 wt% at 30 C.
