“…However, when the AgNPs are deposited onto the membranes at high concentrations, they block the pores of the membranes, hence reducing the water fluxes . MD membrane fouling studies in the literature are dominated by organic fouling and inorganic fouling (also referred to as scaling) . Although few studies on biofouling of MD membranes have been reported in the literature, biofilm formation has been recorded to significantly decrease the efficiency of MD systems .…”

Membrane distillation (MD) is a thermally driven process that uses low‐grade energy to operate and has been extensively explored as an alternative cost‐effective and efficient water treatment process compared to conventional membrane processes. MD membranes are synthesized from hydrophobic polymers, e.g. polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE) or polypropylene (PP), using various methods including phase inversion and electrospinning techniques. Recent literature on MD membranes clearly shows their important role in surface water/wastewater treatment and seawater desalination. Modification of MD membranes with nanoscale materials significantly improves their performance, preventing wetting and fouling. This review presents a critical assessment of the progress on the use of nanomaterials for the modification of MD membranes. The techniques commonly used to synthesize MD membranes, the modifications that have been adopted for the incorporation of nanomaterials onto membranes, and the unique properties these nanomaterials impart on the membranes are discussed. The use of modified membranes in different MD configurations and their application in groundwater, surface water, wastewater, brackish water and seawater treatment is reviewed. Finally, cost implications, commercial viability, environmental sustainability, and future prospects of MD are also discussed to elucidate promising approaches for a future and successful implementation of MD at an industrial scale. © 2019 Society of Chemical Industry

“…The hydrophobicity of ceramic membranes can be achieved through chemical modification, surface morphology modification, or by the combination of them. Hydrophobized ceramic membranes are usually prepared via chemical modification and especially, by using organosilanes as surface modifying agents [22]. In this case, several organosilanes can be used, as for example, chloroalkylsilanes, fluoroalkylsilanes (FAS), polydimethylsiloxane (PDMS), triethoxy-1H,1H,2-H,2H-perfluorodecyltriethoxysilane [23][24][25].…”

“…An additional posttreatment is therefore necessary to improve the hydrophilicity of the nanofibers, and the surface hydrophilic modification can be realized by plasma treatment. Plasma is an effective grafting method for nanofibrous materials, and researchers have found that plasma treatment is useful for the formation of a hydrophilic layer on a hydrophobic base membrane, or vice versa . Despite the benefits, the stability of the plasma treatment is still an open question.…”

This paper provides a comprehensive analysis of microwave‐induced low‐vacuum argon plasma treatment effects on the hydrophilic stability of various polymeric nanofiber webs. After plasma modification, samples are kept dry at room temperature in a dark place for the experiments, and the wettability of the nanofibers is improved by plasma treatment. The stability of the plasma‐treated hydrophilic nanofiber webs is observed for 55 days using water contact angle measurements. Different polymeric nanofiber webs show different stability. Based on the contact angle measurements, the surface starts to lose hydrophilicity during the first week after plasma treatment. The structural changes are examined by pore size measurements, scanning electron microscopy, and Fourier transform infrared spectroscopy. Two of the selected nanofiber webs are used as microfilters for separation of oily wastewater with a cross‐flow separation unit to measure the effect of the plasma treatment under wastewater. The permeability and selectivity of the plasma‐treated and untreated samples are compared. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46751.
