Membrane distillation (MD) is a thermally driven separation process where a hydrophobic and microporous membrane separates nonvolatile compounds. Because of its advantages, this process appears as an efficient way to recover water from industrial effluents. However, the commercial membranes used in the MD process still have operational troubles with complex industrial wastewater and against harsh operational conditions. Fouling, wetting, and low time of operation compromise the membrane function and make the total consolidation of MD technology difficult beyond the traditional application (desalination). Membrane modification can be key to mitigating these operational problems, allowing MD's expansion to complex separations. In this context, herein the main technologies to modify the membranes for MD applications of the last five years are comprehensively summarized. Three kinds of postfabrication modifications are focused on: electrospinning, coating, and plasma, including polymeric and ceramic membranes. A critical analysis of each technique is developed, discussing their potentialities and the properties achieved through them. This review enables the understanding of the operational problems of MD technology and leads to finding feasible alternatives to their mitigation. It also clarifies the evolution in membrane modification, discusses the development directions, and points out the future challenges of modifications.

“…However, when vapor passes through the membrane, it partially transfers heat to the material, thereby reducing the temperature gradient. Therefore, it is important that the membrane has low thermal conductivity [14][15][16]. Various types of polymers, for instance, polytetrafluoroethylene (PTFE), polyamide (PA), polypropylene (PP) are used in MD [17][18][19].…”

Phenols are one of the most common surface water pollution. The discharge of phenolic waters into water bodies and streams sharply degrade their general sanitary condition, since these compounds have a toxic effect, and phenols can intensively absorb oxygen dissolved in water, which negatively affects the life of organisms in water bodies. Therefore, water treatment of phenols is an important environmental problem. In this study, the hydrophobic polyethylene terephthalate track-etched membranes (PET TeMs) were tested in water treatment from phenol by direct contact membrane distillation (DCMD). Hydrophobic PET TeMs were obtained by UV-graft polymerization of styrene, triethoxyvinylsilane with the addition of vinylimidazole (VIM), as well as by coating with fluorine-containing silanes. Scanning electron microscopy (SEM), Fourier-transform infrared (FTIR) spectroscopy and liquid entry pressure (LEP) analysis were used for membrane characterization. The contact angle after modification of PET TeMs was reached more than 130°. The efficiency of water purification from phenol was evaluated by water-flux measurements and fluorimetric method. The phenols solution was used at a concentration of 0.5, 1 and 2 g/l. The largest permeate flux of hydrophobized membranes was 1.1 kg/ m2•h.

“…Promising results were obtained for the membranes formed by electrospinning method and the membranes with addition of different fillers, e.g., carbon nanotubes, titanium and silicon dioxide or talc [27,28,29,30,31,32]. In addition to membranes made of polymers, ceramic membranes are also presented, which create a chance for applications requiring particularly durable membranes [33,34]. Many new types of membranes and methods for their preparation and the possibility of their use in the MD process are described extensively in review articles [8,16,18,34,35].…”

The effect of talc addition on the morphology of capillary membranes formed by a thermally induced phase separation (TIPS) method was investigated in the presented work. The usability of such formed membranes for membrane distillation was evaluated. Two types of commercial capillary polypropylene membranes, fabricated for microfiltration process, were applied in the studies. A linear arrangement of polymer chains was obtained in the walls of membranes formed without a talc addition. In the case of membranes blended with talc, the linear structure was disordered, and a more porous structure was obtained. The changes in morphology enhanced the mechanical properties of blended membranes, and their lower thermal degradation was observed during 350 h of membrane distillation studies. Long-term studies confirmed the stability of talc dispersion in the membrane matrix. A leaching of talc from polypropylene (PP) membranes was not found during the membrane distillation (MD) process.
