“…One of the early applications of 3D printing was on module spacer design and development utilizing a net-design spacer for membrane separation [6]. Since then, different types of membrane spacer designs have been reported for applications such as reverse osmosis (RO), ultrafiltration (UF) [7], membrane distillation (MD) [8], forward osmosis (FO) [9], etc. There have been attempts on direct fabrication of 3D-printed polymeric [10] and ceramic [11] membranes, or as substrate to membranes [12].…”

“…When compared with standard commercial spacer, the 3D-printed spacer with column design obtained two orders of magnitude lower specific energy consumption than the standard spacer. Using polyjet and FDM 3D printing, Yanar et al [9] investigated the mechanical properties, flux and fouling performance under FO operation of three diamond-shaped spacer made from ABS, polylactic acid (PLA) and PP (see Fig. 6d).…”

“…3D printing is a precise fabrication method that produces complex structures in macroscale [52,53]. Although was previously unheard of to say the same thing about micro and nanoscales, recent developments in 2-photon polymerization by spatiotemporal focusing of the femtosecond laser pulses made it possible to have ≈100 nm resolution [54].…”

3D printing has recently influenced membrane science. As a green alternative to current membrane fabrication methods, 3D printing prevents the mixing of highly toxic chemicals into water through its sustainable production. Furthermore, the risk of exposure to these toxic materials and of mechanical accidents during the fabrication is also attenuated. This type of in-situ fabrication eliminates logistic-based problems caused by transportation and packaging. Eliminating packaging and reducing transportation and precision-based waste also reduces CO2 emissions. The advantages of 3D-printed membranes are correlated with each other and promote a greener environment. In this article, we collect their contributions under the sub-titles of sustainability, risk reduction, cost-effectiveness, precision and mobility.

“…The accumulation of unwanted foulants inside or on the membrane has been identified as one of the major challenges for the PRO process by many experimental studies [13][14][15][16][17][18][19]. The occurrence of membrane fouling is attributed to various causes such as the influent of colloidal particles; the deposition and adsorption of organic compounds; the crystallization of dissolved inorganic compounds; and the adhesion, accumulation, and interfusion of microorganisms [19,[97][98][99][100][101][102][103]. As a result of the fouling propensities, many harmful influences such as cake-enhanced osmotic pressure [104,105] aggravate the performance of the PRO process.…”

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.
