“…On the contrary, chemical pretreatment involves the use of chemical additives to remove the foulant from the feed via coagulation [51], oxidation [24] and chlorination [52]. Coagulant such as aluminium chloride and sodium aluminate could remove phosphate from calcium phosphate-rich wastewater [51].…”

“…Coagulant such as aluminium chloride and sodium aluminate could remove phosphate from calcium phosphate-rich wastewater [51]. A reduction of biofouling potential could be made through disinfection using chloramine [52]. The chloramine inhibits the growth of intact bacterial cells, which further prevents biofilm formation over the membrane surface.…”

Forward osmosis (FO) is an osmotically driven membrane separation process. It is potentially applied in various industries for nutrient recovery and water reclamation. Although FO showed a lesser fouling tendency than other pressure-driven membrane processes, the solutes in the feed solution would still deposit on the membrane surface, forming a fouling layer that resists water permeation. For that reason, fouling mitigation is a trending issue in the FO process. A better understanding of the fouling mechanism is required before opting for the appropriate strategy to mitigate it. This article describes the fouling mechanism based on different foulant presented in the feed, followed by a method in relieving fouling in the FO process.

“…Due to this, colloidal fouling was reduced as a consequence, and water flux was increased 104 . On the other hand, chemical pre‐treatment is used to remove the foulants from the FS in the OPDPs using chlorination, 105 oxidation, 106 and coagulation processes 107 using chemical additives. Chloramine disinfection was used to reduce biofouling risk in the FO membrane system.…”

The scarcity of freshwater is one of the major challenges to the civilized community around the World. So, the various engineered processes have been developed for the remediation of this problem such as osmotic pressure-driven processes (OPDPs). OPDPs includes forward osmosis and pressure retarded osmosis, which have gained enormous attention and becoming a flexible membrane-based technology for desalination and wastewater treatment. The most significant components of the OPDPs to be efficient are the membranes and the draw solution. Although numerous studies highlighted the membrane fouling and concentration polarization are one of the critical parameters to assess the system efficiency in the OPDPs and other pressure driven membrane processes. This study delivers an up-to-date review of the OPDPs in terms of concentration polarization, membrane fouling (organic, inorganic, and biofouling), foulant interactions, remedial strategies, monitoring and characterization techniques, and future directions of research. Numerous foulant interactions are also elaborated for the OPDPs in the field of the membrane separation technique. State of the art in antifouling membrane fabrication methods are critically reviewed along with different remedial strategies for fouled membranes in OPDPs.
