“…of publications (related to "Forward Osmosis") No. of publications (related to "Produced Water and Forward Osmosis") FO requires a lower energy consumption, which is a significant advantage in order to reduce the amount of PW as an oil/brine waste [38][39][40]. Out of the different techniques examined for PW treatment, FO was recognized as a technology that can withstand certain PW processes having increased TDS [41].…”

Worldwide water shortage and significant issues related to treatment of wastewater streams, mainly the water obtained during the recovery of oil and gas operations called produced water (PW), has enabled forward osmosis (FO) to progress and become advanced enough to effectively treat as well as retrieve water in order to be productively reused. Because of their exceptional permeability qualities, thin-film composite (TFC) membranes have gained increasing interest for use in FO separation processes. This research focused on developing a high water flux and less oil flux TFC membrane by incorporating sustainably developed cellulose nanocrystal (CNC) onto the polyamide (PA) layer of the TFC membrane. CNCs are prepared from date palm leaves and different characterization studies verified the definite formations of CNCs and the effective integration of CNCs in the PA layer. From the FO experiments, it was confirmed that that the membrane with 0.05 wt% of CNCs in the TFC membrane (TFN-5) showed better FO performance in PW treatment. Pristine TFC and TFN-5 membrane exhibited 96.2% and 99.0% of salt rejection and 90.5% and 97.45% of oil rejection. Further, TFC and TFN-5 demonstrated 0.46 and 1.61 LMHB pure water permeability and 0.41 and 1.42 LHM salt permeability, respectively. Thus, the developed membrane can help in overcoming the current challenges associated with TFC FO membranes for PW treatment processes.

“…As a result, coagulation/Mbs may have a completely different impact on fouling in the FO membrane. Huang et al 113 studied the membrane fouling behavior, flux, and rejection rate using a series of pre‐treatments, including Mbs, coagulation (C), and their combination process (Mbs + C) using textile wastewater as FS in the FO process. The combination of Mbs + C resulted in a higher rejection rate (>98%) and a smaller flux drop (~40%) through the FO membrane.…”

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.

Printing and dyeing wastewater has characteristics of high pH, poor biodegradability, complex composition, and a large amount of water, which means it remains a daunting environmental issue. The development of efficient and economic printing and dyeing wastewater treatment technology has gained considerable interest in the field of environmental protection. The performance of ultrafiltration/ forward osmosis (UF/FO) hybrid system focused on recycling valuable materials in actual printing and dyeing wastewater was investigated. The effects of pressure, temperature, membrane orientation, and feed pH on membrane performance were also studied. The results showed that the optimal pressure and temperature (T) are 0.15 MPa and 25 °C, respectively; active-layer facing feed solution (AL-FS) mode at pH 7 was used for a UF/FO hybrid system. The recovery of terephthalic acid (TPA) was 99.78% under pH 4. This paper provided a resourceful proposal for the treatment of printing and dyeing wastewater.
