“…This has also been reported in a past study on FO-RO hybrid process-based direct potable reuse [20]. Another study that used secondary wastewater as feed in the long-term FO operation reported that there was continual irreversible fouling [21]. The degree of FO fouling, cake layer compaction, and fouling reversibility are strongly influenced by the initial water flux [16] [22] [23].…”

“…Based on Darcy's law, MFI was established to relate the permeation flux to the thickness of the cake layer where the total resistance to flow is the sum of the membrane resistance and the cake resistance (Schippers & Verdouw, 1980). Under constant transmembrane pressure, a linear relationship exists between t/V and V during the cake filtration where t is the filtration time (s) and V is the total filtrate volume (L) (Javeed et al, 2009; Zhan et al, 2020). The MFI of the membrane is determined as the slope of the linearized cake filtration equation as follows (Zhan et al, 2020):

\frac{t}{V} goodbreak= \frac{μ R_{m}}{∆ P A_{m}} goodbreak+ \frac{italicμα C_{f}}{2 ∆ P A_{m}^{2}} V,

italicMFI goodbreak= \frac{italicμα C_{f}}{2 ∆ P A_{m}^{2}},

where ΔP is the applied transmembrane pressure (Pa), μ is the solution viscosity (Pa·s), α is the specific cake resistance (m −2 ), C f is the feed concentration (mg/L), R m is the membrane resistance (m −1 ), and A m is the membrane surface area (m 2 ).…”

The blend polyether imide‐sulfonated poly (ether ether keton) (PEI‐sPEEK) hollow fibre membrane was prepared for oily wastewater treatment of the natural gas liquid plant (NGL‐900, Gachsaran, Iran) through a side‐stream membrane bioreactor (MBR) process. Using PEI/sPEEK ratio of 90/10, a good compatibility of PEI and sPEEK polymers was achieved by DSC analysis. The modified membrane showed an open structure with large finger‐likes, overall porosity of about 80% and mean surface pore size of 10 nm. In addition, the membrane hydrophilicity significantly improved as water contact angle reduced from about 82° to 58°. In the MBR process, the improved membrane presented oil rejection, COD, TSS and turbidity reduction of about 99.9%, 99.7%, 98.9%, and 99.7%, respectively. The membrane showed a good antifouling property with flux recovery ratio (FRR) of 80.2% where the cake filtration was the dominant fouling mechanism. The modified membrane can be a promising alternative for treatment of industrial oily wastewater due to the enhanced properties.

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.
