“…Although some initial fouling and cleaning data have been reported for aquaporin-based membranes (49), further exploration of the longterm robustness of such membranes in actual desalination processes is needed. Examples of such studies include fouling properties, tolerance to common membrane-cleaning chemistries, and stability of AQP-based membranes.…”

Increasing demands for energy-efficient separations in applications ranging from water purification to petroleum refining, chemicals production, and carbon capture have stimulated a vigorous search for novel, high-performance separation membranes. Synthetic membranes suffer a ubiquitous, pernicious trade-off: highly permeable membranes lack selectivity and vice versa. However, materials with both high permeability and high selectivity are beginning to emerge. For example, design features from biological membranes have been applied to break the permeability-selectivity trade-off. We review the basis for the permeability-selectivity trade-off, state-of-the-art approaches to membrane materials design to overcome the trade-off, and factors other than permeability and selectivity that govern membrane performance and, in turn, influence membrane design.

“…A challenge in fabricating a PRO membrane is to simultaneously satisfy a high water permeability and a great tensile strength, as noted in Section 4.1.1. To fabricate such a membrane, many bold research studies on the topic of a "state-of-art membrane" have been conducted [36,[107][108][109][110][111][112][113][114]. Among the diversity of such studies, studies regarding aquaporin membranes and graphene membranes are attracting attention.…”

Modeling and Simulation Studies Analyzing the Pressure-Retarded Osmosis (PRO) and PRO-Hybridized Processes

Pressure-retarded osmosis (PRO) is viewed as a highly promising renewable energy process that generates energy without carbon emissions in the age of the climate change regime. While many experimental studies have contributed to the quest for an efficiency that would make the PRO process commercially viable, computational modeling and simulation studies have played crucial roles in investigating the efficiency of PRO, particularly the concept of hybridizing the PRO process with reverse osmosis (RO). It is crucial for researchers to understand the implications of the simulation and modeling works in order to promote the further development of PRO. To that end, the authors collected many relevant papers and reorganized their important methodologies and results. This review, first of all, presents the mathematical derivation of the fundamental modeling theories regarding PRO including water flux and concentration polarization equations. After that, those theories and thermodynamic theories are then applied to depict the limitations of a stand-alone PRO process and the effectiveness of an RO-PRO hybridized process. Lastly, the review diagnoses the challenges facing PRO-basis processes which are insufficiently resolved by conventional engineering approaches and, in response, presents alternative modeling and simulation approaches as well as novel technologies.

“…Llenas et al [67] investigated the performance of NF membranes (NF270, NF200, NF90 (Dow Filmtec)) and they found them to be more suitable for the pretreatment in RO desalination. Commercially available NF membranes are dominated by polyamide membranes manufactured by interfacial polymerization and many researchers are working on improving the flux of these membranes [68][69][70]. In order to obtain high salt rejection, NF membrane surface has been cross linked to narrow the pore size.…”

Seawater desalination and wastewater treatment for its reuse are rapidly evolving technologies as water crisis is one of the major issues around the globe. Different purification technologies and advancements in the processes, for instance variation in pretreatments for a better separation process and other related aspects are the areas frequently worked on. Evolution of water treatment techniques over last 40 years is fairly vast and new ideas related to nanotechnology are emerging in the industries with a view of more efficient functioning. The article focusses on the large scale water treatment techniques, their characteristics, relative principles, methodology and evolution. It also indicates the variety of membranes manufactured by established company over the years and emphasizes on their different properties and applications with changing compositions. The article narrows down to concentrate on the membrane separation processes as they are globally popular techniques in bulk water treatment.
