Organic fouling inhibition on electrically conducting carbon nanotube–polyvinyl alcohol composite ultrafiltration membranes

Magnéli Ti 4 O 7 modified ceramic membrane for electrically-assisted filtration with antifouling property

“…The antifouling performance of Ti 4 O 7 /Al 2 O 3 membranes with the designed 26 membrane module was first evaluated via the separation of detergent stabilized oily wastewater (peanut-oil-based oil emulsion in this study) which widely exists in restaurant, domestic, marine, and industrial wastewaters. Instead of the traditional gravitational separation method, such stabilized oil emulsion usually requires the more advanced membrane separation technology for effective treatment [21].…”

“…For instance, the PVA-CNT-COOH modified PS-35 membrane developed by Dudchenko and co-workers [26] and the CNT-PVDF capacitive layer modified ultrafiltration (UF) membrane by Zhang and Vecitis [27].…”

In-situ combined dual-layer CNT/PVDF membrane for electrically-enhanced fouling resistance

“…Recent studies used conductive membranes as electrodes, which shortened the distance between cathode and anode thereby reducing electric resistance thus lower energy loss [14,17,18]. Consequently, similar antifouling effects were achieved with simplified configurations [14,[17][18][19][20][21].…”

Coupling Underwater Superoleophobic Membranes with Magnetic Pickering Emulsions for Fouling-Free Separation of Crude Oil/Water Mixtures: An Experimental and Theoretical Study

“…The membrane materials included two commercially available UF membranes made of polysulfone (PS35) and polyacrylonitrile (PAN), and two modified UF membranes with poly(vinyl alcohol) carbon nanotube coating (PVA-CNT) on PS35 (PS35-CNT) and PAN (PAN-CNT). The PVA-CNT coating deposited on the PS35 or PAN support governs the membrane surface properties, including hydrophilicity, but does not influence their rejection properties or permeability, as demonstrated by Dudchenko et al (2014) (Figure 2e). 34 The tendency of the membranes to become wet by oil was measured by allowing a crude oil drop to contact the membrane in a water-filled inverse cell, and measuring the contact angle over a 20 min period.…”
