This chapter presents the exploration of the combined process of wastewater reclamation and seawater dilution using forward osmosis (FO). Wastewater and seawater are the two most abundant water sources that are free of the hydrological cycle and could serve as an alternative potable water source. Forward osmosis was chosen as the an ideal pre-treatment step to dilute seawater prior to desalination at relatively lower energy demand and low fouling propensity. Membrane fouling behavior was studied and investigated using different feed compositions bearing fractions of effluent organic matter (EfOM). The negative surface charge of all organic foulants was reduced by the adsorption of calcium ions. Filtration of feed streams containing single, simple organic foulants revealed that alginate (polysaccharides) and bovine serum albumin (BSA) resulted in significant loss in process performance as a result of permeate flux reduction.The complex mixture of alginate, BSA and humic acid caused severe loss in membrane performance due to dominant favorable synergistic interactions between foulants and between foulants and membrane surface. The forward osmosis process presents a viable alternative for a simple and effective seawater dilution step using wastewater as the feed solution. Process performance can be improved by selecting a foulant resistant membrane with matching flux.

“…So the researchers did lots of research in the direction of resistance to pollution. Coating hydrophilic functional layer on the membrane surface is an effective method to reduce membrane fouling [15]. But post-surface treatment could increase the penetration resistance leading to flux decrease.…”

“…The siricin-coated membrane showed decreased water permeability due to the additional hydraulic resistance, but improved salt rejection as a result of the enhancement of surface negative charge. Resistance to BSA fouling was improved due to enhanced surface hydrophilicity, increased surface negative charge and smoothed surface morphology [19]. Besides, Zhou et al [20] used the natural hydrophilic polymer sericin to react with TMC during the interfacial polymerization process.…”

a b s t r a c t a r t i c l e i n f o Available online xxxx Keywords:Thin film composite fouling surface modification polyamide Membrane (bio)fouling is a major obstacle to many separation and purification processes. Due to the inherent physicochemical properties of some thin film composite membrane surfaces such as polyamide, these are prone to (bio)fouling. Hence, this review highlights recent advances in the design and development of highly resistant thin film composite membrane through surface modification by either coating or grafting with antifouling polymers and/or antimicrobial polymers/biocidal inorganic nanoparticles.
