“…Because of the high thermal conductivity of the ceramic membranes, studies on heat recovery by the module of a ceramic membrane are necessary. High potential for improvement is associated with adapted membrane module design appropriate to specific project requirements . The ceramic membrane sealing in the membrane module can be a challenge to be faced during MD experiments.…”

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.

“…A high concentration of salts in wastewaters makes their biological purification often impossible and such types of effluents are usually not treated by industrial wastewater treatment plant, which enhances a risk of illegal discharge into the environment. The possibility of water evaporation from high concentration brine enables the application of membrane distillation (MD) for desalination of hypersaline water or the treatment of saline wastewater (Duong et al 2015;Gryta 2017;Ji et al 2010;Winter et al 2017). An integration of MD process with crystallization allows to eliminate the salts discharge (Salmón and Luis 2018).…”

“…The porous non-wetted hydrophobic membranes are used in the membrane distillation (Gryta 2017;Wang and Chung 2015;Winter et al 2017). However, the hydrophobic membranes are intrinsically prone to fouling by hydrophobic contaminants due to the strong hydrophobic-hydrophobic interaction (Chew et al 2017;Lin et al 2014;Rácz et al 2015;Rezaeia et al 2017).…”

Therefore, the conventional hydrophobic membranes (made of PP, PTFE and PVDF) are usually applied for desalination of water when the hydrophobic contaminants concentration is relatively low (Gryta 2017;Guillén-Burrieza et al 2011;Winter et al 2017). A progressive wetting of hydrophobic membrane is observed even for clean water, such as seawater, which is attempted to be eliminated by the application of superhydrophobic membranes (Guo et al 2015;Hamzah and Leo 2017;Lin et al 2014;McGaughey et al 2017;Rezaeia et al 2017).…”

Separation of saline oily wastewater by membrane distillation

Membrane distillation was used for the treatment of saline oily wastewaters collected from harbour deoiling installation. The turbidity of these wastewaters was in the range 63-87 NTU, salt concentration was 6-11 g/L and the oil content in the feed was below 40 mg/L. Two types of commercial polypropylene capillary membranes were applied for the process study. The intensive membrane fouling during the wastewater separation was observed. Modules rinsed with water removed the organic deposits formed. However, the CaCO 3 scale was accumulated on the membrane surfaces during 1500 h of the process, resulting in a permeate flux decline by more than 40%. The initial yield of modules was recovered by membrane rinsing with 5 wt% HCl solution. The long-term studies demonstrated that the separated oily wastewaters did not cause wetting of the applied membrane. The degree of retention amounted to 98% for the inorganic compounds and more than 99% for the organic compounds.

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

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.
