“…Recent publications have tended to focus on producing novel ceramic materials specifically to MD, rather than on commercial ceramic membranes. Some examples include kaolin [Al 2 Si 2 O 5 (OH) 4 ], silicon nitride with SiNCO nanoparticles (NPs), bi‐layered yttria‐stabilized zirconia (YSZ), β‐Sialon coated with polydimethylsiloxane (PDMS), alumina and clay (kaolin), alumina support and zeolite mordenite framework inverted (MFI), mud of hydrocyclone laundries of phosphates/zirconia, Tunisian clay, green silica‐based ceramic membrane derived from rice husk ash waste, and silicon dioxide‐coated silicon oxynitride . Each publication reported in detail the fabrication of the membrane.…”

“…The creation of a rough surface, that is, generation of heterogeneity on the surface, is possible to form highly hydrophobic surfaces due to the generation of pillars and the presence of air pockets on the surface . Two studies reported the use of a framework of MFI zeolites as hydrophobic surface modification . One recent study reported the creation of roughness by depositing zinc oxide NPs on omniphobic alumina membranes, which enhanced wetting resistance along with grafting .…”

“…Hubadillah et al and Kujawa et al proved that ceramic‐based MD can be applied to high concentrated solutions without affecting its performance because of lower fouling effect . On the other hand, many authors observed that when increasing the solute concentration at the feed side results in a decrease in permeate flux . This phenomenon is explained by Raoult's law, which states that higher solute concentrations lead to decrease in water vapor pressure.…”

Membrane distillation (MD) has been increasingly studied in the past decade for its potential as a separation process of nonvolatile components. The present study demonstrates a comprehensive overview of the current progress and challenges in the application of ceramic membranes to MD based on the available state of the art.There are already published review papers about MD, but the present study focuses on ceramic membranes, which are still the few used in MD when compared to polymeric membranes. Significant issues such as membrane material, module, characteristics, and hydrophobic modification are discussed. The main operating conditions and their effects on the separation process are given. Current applications of ceramic membranes in MD are also presented. Likewise, challenges and future perspectives associated with MD performance using ceramic membranes are highlighted.A review focused on ceramic membranes applied specifically to MD will contribute for future research in order that this process achieves successful implementation in industry.

“…The hydrophobicity of a membrane causes to pass only vapor through the membrane pores and does not allow the feed solution for penetrating into the membrane pores, consequently wetting them . As a result of the temperature difference between both hot and cold flows, the transmembrane vapor pressure creates and causes to traverse evaporated water molecules from the feed solution to the permeate side , . However, the higher concentration of salt in the hot feed solution results in the reverse flow from pure cold water to the hot stream.…”

Poly(vinylidene difluoride) Membrane Assisted by Modified ZnO/ZIF Nanoparticles for Membrane Distillation

2018

Poly(vinylidene difluoride) (PVDF) polymeric membranes incorporated by synthesized hydrophobic agents were applied for membrane distillation. ZnO nanoparticles were modified with a silane coupling agent (n‐octyltriethoxysilane) and coupled by zeolite imidazole framework (ZIF)‐8 crystals. In particular, hydrophobic and porous membranes were prepared with ZIF crystals and modified ZnO/ZIF‐coupled nanoparticles. The influences of feed concentration and temperature of NaCl solution and seawater during filtration were evaluated. The hydrophobic modified membranes showed a higher permeate flux than pure PVDF membranes at different feed concentrations and feed temperatures. After modification, the porosity increased significantly and the contact angle became larger.

In this article, using the non‐solvent induced phase separation process, a new microporous membrane with the semi‐interpenetrating polymer network (semi‐IPN) structure was produced. For this membrane, polydimethylsiloxane (PDMS) polymer is crosslinking and poly(vinylidene fluoride) (PVDF) polymer is linear, by changing the mass ratio of PDMS/PVDF, the structure and the performance of the prepared membranes were studied. The membranes were also investigated by attenuated total reflection‐Fourier transform infrared (ATR‐FTIR), scanning electron microscopy–energy‐dispersive X‐ray spectroscopy, X‐ray diffraction, thermogravimetric analysis, and water contact angle, etc. ATR‐FTIR spectroscopy confirmed the formation of semi‐IPN; compared with the PDMS/PVDF polymer without semi‐IPNs structure, the viscosity of the semi‐IPNs structured casting solution increased, membrane mechanical property increased but its hydrophobicity decreased. Using the resulting membranes for the vacuum membrane distillation desalt of the NaCl solution (30 g/L), 99.9% salt rejection and reasonable flux were obtained. © 2017 Wiley Periodicals, Inc. J.
