Summary: This study developed a low-cost ceramic microfiltration membrane using kaolinite and perlite for clarifying dairy and textile wastewaters. The optimal membrane consisted of 50 wt% perlite sintered at 1050 degrees C, with a permeability of 1779 L h-1 m-2 bar-1 and an average pore diameter of 1.25 μm. It effectively removed over 97% of turbidity and significant amounts of organic carbon from both dairy and textile wastewaters. The flux was mostly recovered after membrane cleaning, indicating its potential for industrial scaling-up.

Summary: The study demonstrated that landfill leachate can be efficiently treated using membrane distillation, achieving excellent rejection rates for organic carbon, phosphate, and metal ions under all tested conditions. The rejection rate of ammonia nitrogen can be increased by feed acidification, enhancing membrane fouling resistance. Additionally, energy consumption analysis indicated that waste heat from an incineration plant is sufficient to drive on-site treatment using MD.

Summary: In this study, the reduction of fouling in Conventional Membrane Bioreactor (C-MBR) and Modified Membrane Bioreactor (M-MBR) was compared through incorporated modification. The introduction of Self-forming dynamic membrane (SFDM) in M-MBR successfully reduced fouling and prolonged the operation time.

Summary: Forward osmosis (FO) technology shows great potential in liquid food concentration due to its ability to retain flavor components and bioactive substances completely. However, membrane fouling remains a major obstacle affecting FO performance and efficiency. The study found that utilizing the AL-FS mode for orange juice concentration, increasing the cross-flow rate, and pretreating feed solutions can effectively enhance water flux and reduce fouling resistance, while microfiltration pretreatment significantly reduces the content of major foulants.

Summary: Preozonation of casein solutions in dairy wastewater can effectively mitigate membrane fouling in ultrafiltration. The process disrupts interactions between casein molecules, leading to the formation of a more open-and-loose fouling layer on the membrane, ultimately reducing fouling levels.

Summary: Membrane distillation (MD) is a thermally driven technology used for desalination and water reuse. However, algal organic matter (AOM) can foul the membrane and affect the long-term stability of MD. This study investigated the effects of temperature on membrane fouling caused by heated AOM. The results showed that heating led to cell lysis and the release of carbohydrates and proteins from AOMs, resulting in increased fouling of the membrane. Higher proportions of protein, lipids, and saturated fats also contributed to severe fouling.

Summary: This study investigated the effects of solids retention time (SRT) on the membrane fouling in a microalgal-bacterial membrane photobioreactor (MPBR). The results showed a nonlinear relationship between membrane fouling and SRT, with the fastest fouling observed at SRT 20 d. Gel layer formation was identified as the predominant fouling mechanism. X-ray photoelectron spectroscopy results revealed significant differences in the surface composition of the microalgal-bacterial consortia at different SRTs. The highest membrane fouling at SRT 20 d was attributed to the highest concentration of bound EPS and SMP. Optimal SRT values that control the balanced growth of microalgae and bacteria are crucial for delaying membrane fouling in microalgal-bacterial MPBR.

Summary: This article presents a review of the application of artificial intelligence algorithms for predicting membrane fouling. By using techniques such as artificial neural networks and fuzzy logic, more accurate predictions and control of membrane fouling can be achieved. Future research should focus on optimizing AI techniques for more precise prediction of membrane fouling and optimization of membrane-based processes.

Summary: Zwitterionic surface engineering was employed to improve the antifouling ability of hollow-fiber membranes. A flow-through coating method using zwitterionic organosilica material was used to introduce zwitterions onto the membrane, which was then incorporated into a membrane bioreactor (MBR) to demonstrate enhanced fouling control. The zwitterion-coated membrane showed superior fouling resistance in the MBR, with improved critical flux, extended fouling cycle, and higher resistance to key foulants such as extracellular polymeric substances (EPS) and soluble microbial polymer (SMP). The interfacial free energy analysis revealed that zwitterions altered the interfacial interaction between the membrane and the fouling substances, leading to elevated energy barrier for foulants attachment.

Summary: The fouling of seawater reverse osmosis membranes is a persistent challenge in desalination. This study monitored the operational performance of a desalination plant for 7 years and the fouling development in different areas of membrane modules. The findings showed that operational performance declined over time and fouling mainly occurred at the feed side of the modules, with the highest microbial diversity. Keystone species like Chloroflexi and Planctomycetes played an important role in maintaining community structure and biofilm maturation. Polysaccharides, soluble microbial products, marine humic acid-like substances, and inorganic substances contributed to fouling. Overall, biofouling had a significant impact on membrane fouling after 7 years of operation.

Summary: Water pollution is a severe issue caused by population growth and human activities, worsened by limited freshwater resources and increasing water demands. Among various contributors, the dairy industry stands out due to the high concentrations of harmful contaminants in dairy wastewater. Traditional treatment methods have limitations, and membrane separation technology (MST) has emerged as a promising alternative with benefits such as efficient separation, minimal impact on product quality, and lower energy consumption. However, challenges like membrane fouling and concentration polarization exist, and strategies like pre-treatment and 3D printing technology have been implemented to address them.
