“…During the filtration process, both UF and MF membranes underwent a substantial flux reduction ( Supplementary Materials, Figure S2 ). Flux decline during filtration occurs due to the fouling of the membranes through pore fouling and cake formation [ 16 , 19 , 32 ]. Also, employing a dead-end filtration system could have played a role in reducing the flux.…”

“…The SPS TiO 2 membranes exhibited absorbance and photocatalytic activity under visible light [ 21 ]. Therefore, the self-cleaning performance and recyclability of the membranes were investigated in three cycles using a dead-end vacuum filtration device under visible-light conditions [ 32 ]. The surface of the membrane was illuminated with two xenon arc lamps with a power of 35 W, each with an irradiance of 2.16 mWcm −2 .…”

This study investigated the performance of photocatalytic titanium dioxide microfiltration membranes with an average pore size of approximately 180 nm and ultrafiltration membranes with an average pore size of around 40 nm fabricated with the suspension plasma spray process. The membranes were evaluated for their filtration performance using SiO2 particles of different sizes and polyethylene oxide with molecular weights of 20 kDa to 1000 kDa, and the fouling parameters were characterized. The rejection rate was enhanced by increasing the thickness of the membranes. This effect was more pronounced with the ultrafiltration membranes. The rejection rate of the ultrafiltration membrane was improved significantly after filling the larger pores on the surface with agglomerates of titanium dioxide nanoparticles. The self-cleaning performance of the membranes was assessed under visible light. Both ultrafiltration and microfiltration membranes showed a flux recovery under visible light illumination due to the photocatalytic activity of titanium dioxide. The membranes also show a flux recovery of more than 90%.

The complex composition of emulsions often adversely affects separations. When using hydrophilic membranes for oil-in-water emulsions, the oil and other components reduce hydrophilicity, flux, and separation efficiency. The separation of colored emulsions poses a challenge to membrane technology. This work reports a method to inlay hydrophilic particles on the surface of MIL-88A. The modified MIL-88A can form a hydrophilic coating on the membrane that is resistant to scouring. Thanks to the randomly distributed rod-like structure, this grooved coating has remarkable resistance to contamination. Flux can be restored by water washing. A flux close to 5000 L m −2 h −1 bar −1 is consistently maintained in 10 emulsion separations. The modified membrane removes 99% of dyes in addition to oil when treating colored emulsions. Dyes adsorbed to the surface can be degraded by the photo-Fenton reaction under visible light, which ensures the ability to treat colored emulsions continuously.
