“…Techniques like AFM (atomic force microscopy) and XRD (x-ray diffraction) have been employed to characterize the surface structure, roughness of the membranes [5,113,[116][117][118][119] and the crystal composition of the scales formed on the membrane surface, respectively [91,118,[120][121][122]. FTIR (Fourier transform infrared spectrometer) has been used to assess chemical composition of foulants (like functional groups, biopolymers, polysaccharides or humic acids), which helps in understanding the interaction and bonding between the foulants and the membrane surface [95,121,[123][124][125][126]. Also, the contact angle (Table 1) and the zeta potential [123,127] are measured on the membrane surface to evaluate the change in surface hydrophobicity and charge due to fouling and wetting, respectively.…”

Apart from these primary analytical techniques, many water quality analysis experiments are also carried out in both feed and permeate water to gain an understanding of the feed water constituents influencing the mechanism of fouling and wetting.…”

Fouling and wetting of membranes are significant concerns that can impede widespread application of the membrane distillation (MD) process during high-salinity wastewater reclamation. Fouling, caused by the accumulation of undesirable materials on the membrane surface and pores, causes a decrease in permeate flux. Whereas membrane wetting, the direct permeation of the feed solution through the membrane pores, results in reduced contaminant rejection and overall process failure. Lately, the application of MD for water recovery from various types of wastewaters has gained increased attention among researchers. In this review, we discuss fouling and wetting phenomena observed during the MD process, along with the effects of various mitigation strategies. In addition, we examine the interactions between contaminants and different types of MD membranes and the influence of different operating conditions on the occurrence of fouling and wetting. We also report on previously investigated feed pre-treatment options before MD, application of integrated MD processes, the performance of fabricated/modified MD membranes, and strategies for MD membrane maintenance during water reclamation. We also discussed energy consumption and economic aspects of MD for wastewater recovery. Throughout the review, we engage in discussions highlighting research needs for furthering the development of MD: notably the incorporation of MD in the overall wastewater treatment and recovery scheme (including selection of appropriate membrane material, suitable pre-treatment or integrated processes, and membrane maintenance strategies), and the application of MD in long-term pilot-scale studies using real wastewater.

“…This is attributed to the electrostatic repulsion between particles with the same electric charge that causes the particles’ segregation [ 41 ]. The PVDF membrane is negatively charged over the entire pH range due to the C-F group’s electronegative charge [ 42 ], whereas TiO 2 particles show positive zeta potential in acidic conditions and start to fall off with the increase in pH. The zeta potential of TiO 2 /PVA coated PVDF membrane is positive in acidic conditions and becomes negative in alkaline conditions.…”

Tailoring the Effects of Titanium Dioxide (TiO2) and Polyvinyl Alcohol (PVA) in the Separation and Antifouling Performance of Thin-Film Composite Polyvinylidene Fluoride (PVDF) Membrane

In this study, thin-film composite (TFC) polyvinylidene fluoride (PVDF) membranes were synthesized by coating with titanium dioxide (TiO2)/polyvinyl alcohol (PVA) solution by a dip coating method and cross-linked with glutaraldehyde. Glutaraldehyde (GA) acted as a cross-linking agent to improve the thermal and chemical stability of the thin film coating. The incorporation of TiO2 in the film enhanced the hydrophilicity of the membrane and the rejection of dyes during filtration. The layer of TiO2 nanoparticles on the PVDF membranes have mitigated the fouling effects compared to the plain PVDF membrane. The photocatalytic performance was studied at different TiO2 loading for the photodegradation of dyes (reactive blue (RB) and methyl orange (MO)). The results indicated that the thin film coating of TiO2/PVA enhanced photocatalytic performance and showed good reusability under UV irradiation. This study showed that nearly 78% MO and 47% RB were removed using the TFC membrane. This work provides a new vision in the fabrication of TFC polymeric membranes as an efficient wastewater treatment tool.
