“…In addition, it was shown that pretreatment in the form of filtration, especially ultrafiltration, enhances the efficiency of the FO process. In further studies, Dova et al [9,10] investigated and modeled the impact of process parameters (e.g., membrane characteristics, feed and draw solution concentrations, and flow rates) on process performance using thin-film composite aromatic polyamide RO membranes.…”

“…Nevertheless, FO has been used to treat industrial wastewaters (at bench-scale) [2][3][4], to concentrate landfill leachate (at pilot-and full-scale) [5][6][7], and to treat liquid foods in the food industry (at bench-scale) [8][9][10][11][12][13][14][15][16]. FO is also being evaluated for reclaiming wastewater for potable reuse in life support systems (at demonstration-scale) [17][18][19][20], for desalinating seawater [21,22], and for purifying water in emergency relief situations [23].…”

“…The process has also been applied in food processing, in emergencies such as natural disasters as an osmotic concentration of liquid foods [18][19][20][21][22][23][24][25][26]. As previously stated, it is a robust membrane separation technique that boasts of good rejection of a broad range of pollutants and foulants and dissolved ions.…”

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.

“…Membrane fouling is by far the most serious problem found in separation processes such as water desalination, industrial water treatment, juice concentration, and hemodialysis [1][2][3]. Among the other types of fouling, organic fouling and biofouling are the most severe in nature and pose a serious challenge for membranes based separation processes such as seawater desalination and wastewater reclamation.…”
