Evaluation of forward osmosis as a pretreatment process for multi stage flash seawater desalination

Abstract: The present study evaluates the feasibility of applying forward osmosis (FO) process for the pretreatment of feed solution to a Multi Stage Flash (MSF) desalination plant. For the first time, real brine reject and real seawater were used as the draw solution and the feed solution, respectively in the FO process. The FO pretreatment is expected to dilute the brine reject and reduce the concentration of divalent ions, which are responsible for scale formation on the surface of heat exchanger in the MSF evaporato… Show more

“…MSF technology has been in operation since the sixties and gained great credit for the capability to handle the harsh environmental conditions of seawater in the Middle East. Due to the salinity of seawater in the Middle East, the total dissolved solids (TDS) of the expelled brine from the MSF plant usually is about 80 g/L, 1.37M NaCl [15]. The salinity of seawater brine reject is higher than the salinity of seawater (35 g/L), around 2.3 times higher, which provides tremendous osmotic power for the PRO process when coupled with a low salinity feed solution such as TSE, TDS 0.026M NaCl (1.5 g/L) [7].…”

“…The salinity of seawater brine reject is higher than the salinity of seawater (35 g/L), around 2.3 times higher, which provides tremendous osmotic power for the PRO process when coupled with a low salinity feed solution such as TSE, TDS 0.026M NaCl (1.5 g/L) [7]. In addition to its high osmotic pressure, the temperature of brine reject's is always from 10 • C to 15 • C higher than seawater, which provides an additional advantage since both permeation flow and osmotic pressure of the membrane incline to increase when a higher feed solution's temperature occurs [15]. Coupling the brine reject with the TSE as a source of salinity gradient has a high prospect for generating power in the PRO as a result of its high osmotic energy.…”

“…In various membrane processes, forward osmosis (FO) utilizes the osmotic pressure difference between the feed (FS) and draw solutions (DS) to induce spontaneous water diffusion across a semipermeable membrane, which is different from pressure‐driven membrane processes, such as reverse osmosis (RO), nanofiltration, and ultrafiltration (UF). FO technology has recently attracted great interest in industrial application and academic research due to its low hydraulic pressure, fouling tendency, and energy requirement …”

“…FO technology has recently attracted great interest in industrial application and academic research due to its low hydraulic pressure, fouling tendency, and energy requirement. [1][2][3] During FO process, FO membrane is crucial and determines FO application and separation efficiency. However, existing FO membranes often exhibit low water permeability due to internal concentration polarization (ICP).…”
