A novel nanofiltration membrane, whose active layer consists of 98.6 wt% a thermocatalytic perovskite with composition Sr0.85Ce0.15FeO3-δ (CSF), 1.0 graphene oxide (GO), and 0.4 humic acid-like (HAL) crosslinker, was deposited over commercial flat-sheet polyethersulfone support good reproducibility by simple 1-step coating procedure. The synergistic coupling CSF the crosslinked GO resulted in a...

To evaluate the significance of thin-film composite membrane surface morphology on water productivity, flat-sheet experiments were conducted with silicon dioxide, titanium dioxide, and cerium dioxide nanoparticles. The polyamide thin-film active layer exhibited a valley and ridge morphology that was directly related to the surface roughness, and was found to contribute to particle accumulation ...

Feed water that need to be pre-treated before using methods such as, microfiltration, Ultrafiltration, nanofiltration and reverse osmosis is characterized by containing turbidity, bacterial content and total dissolved solid which causes fouling and scaling in membrane performance. Thus, it is necessary to develop a method which is cost effective. Pre-treatment has been shown as a good method to...

We develop a model of interacting zwitterionic membranes with rotating surface dipoles immersed in monovalent salt and implement it field theoretic formalism. In the mean-field regime salt, electrostatic forces between are characterized by non-uniform trend: at large membrane separations, interfacial on opposing sides behave as like-charge cations give rise to repulsive interactions; short anio...

The efficiency of nanofiltration to purify the tyrosol present in olive mill wastewaters (OMWWs) has been studied. similar molecular weight and sucrose existing this kind by-products restricts discrimination between both molecules through a membrane process, but interest phenolic compounds be applied cosmetics pharmacology greatly motivates its recovery at highest purity possible. Thus, two dif...
