Membrane separation processes have become increasingly popular in many industries because of their ability to treat wastewater and purify water. However, one of the main problems related to the processes is organic fouling, which can significantly reduce their efficiency and cause membrane damage. This review provides a summary of the various forms of organic fouling that can occur in membrane separation methods and examines the factors that lead to their development. The article evaluates the progress made in different techniques designed to manage and reduce organic fouling, such as physical cleaning methods, chemical cleaning agents, and modifications to the membrane surface, including ultrasonic and membrane vibration methods. The review also highlights recent advances in emerging 3D printing technology to mitigate membrane fouling. Finally, the review provides a brief summary of the conclusions and future directions for research in the field of organic fouling control and mitigation in membrane separation processes.

“…Coagulation pretreatment can be an effective solution to simultaneously reduce membrane fouling and enhance virus removal. − Kreißel et al reported that low dosages of polyaluminum chloride coagulation treatment could inactivate MS2 and Qβ bacteriophages . Zhu et al demonstrated that over 4-log MS2 removal by iron coagulation enhanced microfiltration, which was significantly higher than microfiltration alone .…”

Viruses found in the effluent and on the membrane surface during ultrafiltration (UF) processes will introduce hidden biosecurity dangers to drinking water. Fe 3+ coagulation coupled with H 2 O 2 to create an in situ membrane cleaning method, and MS2 bacteriophage was used as a model to investigate virus removal by UF when humic acid (HA) was present. The results showed that MS2 was removed by HA based on size exclusion, hydrophobicity, and electrostatic repulsion. Meanwhile, HA slightly reduced MS2 accumulation on the membrane surface by inhibiting MS2 adsorption. Fe 3+ pretreatment (0.08 mmol/L) eliminated MS2 in the effluent by the adsorption and size exclusion of iron flocs. MS2 retained on the membrane surface was reduced through electrostatic repulsion. Iron flocs-H 2 O 2 cleaning destroyed viral protein capsids through HO• oxidation and eliminated all MS2. The mitigation efficiency of membrane fouling was greatly improved with a flux recovery of 97.8%. Moreover, the use of H 2 O 2 was significantly saved (3%) compared to no Fe 3+ pretreatment (12%). This study provides a potentially useful and economically enhanced membrane cleaning method for virus-containing water treatment by UF, which could not only eliminate viruses and mitigate membrane fouling in the UF system but also reduce the use of membrane cleaning agents to save costs.

“…Since these wastes are stable in various conditions, they sometimes stay unchanged in soil and water for many years and cause various complications. Different methods like adsorption [2,3], photodegradation [4,5], separation [6,7], bioand chemical degradation [8,9], coagulation [10,11], filtration [12,13], ultrasonication [14][15][16], etc. are implemented to fully ensure the purity of the water used for drinking or irrigation.…”

In the presented research work, zinc and aluminum containing layered double hydroxides on the polyvinyl alcohol matrix (ZnAl LDH/PVA) were prepared by the co-formation technique and characterized by X-ray diffractometer, Brunauer-Emmett-Teller (BET) and Ultraviolet-visible (UV-Vis) spectroscopy. Both low and high pH is determined as optimal pH for Patent Blue V (PBV) adsorption on the ZnAl LDH/PVA nanocomposite and it is explained by the fact that the dye molecule is zwitterionic. Sorption of Patent Blue V food additive (E 131) on the obtained nanocomposite was studied by Temkin, Freundlich, Langmuir, and Dubinin-Radushkevich (D-R) isotherm models. Based on the obtained isotherm curves, the adsorption of PBV more closely matches Temkin model. The regenerated nanocomposite shows higher adsorption because the specific surface area increased from 5m2 g-1 to 8.94 m2 g-1 by BET analysis
