Summary: This study compared the fouling of alumina and silicon carbide (SiC) ceramic membranes in oil-in-water (O/W) emulsion treatment. The results showed that alumina membranes had higher fouling tendencies at low permeate flux, while SiC-deposited membranes exhibited lower fouling tendencies and higher cleaning efficiencies. The emulsion chemistry, including surfactant concentration, pH, salinity, and Ca2+ concentration, had an impact on membrane fouling. The presence of Ca2+ led to significant irreversible fouling of both membranes.

Summary: This study investigates the application of dynamic membrane filtration using disc ceramic membrane for separating oil-water emulsion. By controlling the trans-membrane pressure and flow velocity of the membrane surface separately, efficient separation and regeneration of the disc ceramic membrane are achieved. The results show that increasing the rotating speed and decreasing the TMP can improve the separation performance of the disc ceramic membrane. Additionally, high flow velocity and low TMP can alleviate membrane fouling and reduce deformation and penetration of oil droplets.

Summary: Ceramic membranes are widely used for oil-water separation due to their high flux, excellent chemical stability, strong hydrophilicity, and good fouling resistance. This study used a co-deposition reaction to modify the surface of ceramic membranes, enhancing their anti-fouling performance. The zwitterion-functionalized ceramic membrane showed improved hydrophilicity and achieved double the permeance compared to the original membrane during the separation of oil-in-water emulsion, indicating good anti-fouling performance.

Summary: Viscous oil separation and its highly efficient recovery is a challenging task in oil/water separation. A nondispersive solvent extraction strategy using a polydopamine modified PVDF Janus membrane has been proposed for efficient recovery of viscous lubricant oil from emulsions. The polydopamine layer facilitates the adsorption and diffusion of oil droplets through the membrane. The optimized membrane exhibited a 70% higher accumulative flux for viscous lubricant oil compared to the contrast PVDF membrane.

Summary: This study evaluates the impact of membrane material, operational pressure, and crude oil concentration on the filtration performance of oil/water emulsion. Results show that fouling resistant membrane offers high permeability for oil/water emulsion, leading to low energy consumption. Sustainable permeability can be achieved when treating 1000 ppm oil/water emulsion, but severe membrane fouling is observed when treating emulsions containing crude oils of >3000 ppm to a point of no flux.

Summary: This study compared the photocatalytic performances of doped and non-doped TiO2 photocatalysts under solar and various types of artificial irradiation. The results showed that the non-doped TiO2 had higher photocatalytic efficiency than the highly visible-light-active TiO2 under natural solar irradiation. Further experiments revealed a lower photocatalytic efficiency in the visible range, even for the most visible-light-active TiO2.

Summary: This study explored the performance of composite photocatalytic membranes made from multiple nanoparticles (TiO2, carbon nanotubes, BiVO4) and polyvinylidene fluoride. These membranes exhibited excellent resistance to fouling, low filtration resistance, high flux, and good flux recovery ratio compared to the pristine membrane. Salinity, pH, and lactose concentration were found to be key factors affecting filtration resistance and rejection performance during the ultrafiltration of dairy wastewater. Lactose in the wastewater increased irreversible resistance and significantly reduced COD rejection during ultrafiltration. Regeneration of fouled photocatalytic membranes was achieved through visible light irradiation, with the membrane containing all constituents showing the best regeneration performance, surpassing the pristine membrane by 30%.

Summary: Bismuth oxybromides with varying urea amounts were synthesized through a solvothermal method. The influence of urea ratio on the morpho-structural properties and photocatalytic activity of the samples was investigated. Characterization techniques such as X-ray diffraction, diffuse reflectance spectroscopy, infrared spectroscopy, Raman spectroscopy, scanning electron microscopy, and surface tension measurements were employed. The urea ratio had a significant effect on the morphology, particle size distribution, and photoactivity of the samples, but a limited effect on the crystalline composition, primary crystallite size, and band gap of bismuth oxybromides. The formation of Bi-based complexes and degraded urea-based products were found to influence the band gap energies and, consequently, the photoactivity. Samples prepared at low urea ratios exhibited the highest degradation efficiency for both rhodamine B and ibuprofen under both UV and visible light irradiations.
