“…In addition, high pressure operations like PRO prefer the outer-selective configuration as it is more mechanically resistant to pressurize from the shell side of modules [25]. However, it is challenging to form a perfect polyamide layer on the outer surface of hollow fibers, as none of the conventional approaches such as roller rolling, air purging and solvent treatment can be applied to effectively remove the excess amine solution before the interfacial polymerization [21][22][23][24][29][30][31].…”

This study reports outer-selective thin-film composite (TFC) hollow fiber membranes with extremely low reverse salt fluxes and robustness for harvesting salinity-gradient energy from pressure retarded osmosis (PRO) processes. Almost defect-free polyamide layers with impressive low salt permeabilities were synthesized on top of robust polyethersulfone porous supports. The newly developed TFC-II membrane shows a maximum power density of 7.81 W m-2 using 1 M NaCl and DI water as feeds at 20 bar. Reproducible data obtained in the 2 nd and 3 rd runs confirm its stability under high hydraulic pressure differences. Comparing to other PRO membranes reported in the literature, the newly developed membrane exhibits not only the smallest slope between water flux decline and ΔP increase but also the lowest ratio of reverse salt flux to water flux. Thus, the effective osmotic driving force could be well maintained even under high pressure operations. For the first time, the effect of feed pressure buildup induced by feed flowrate was evaluated towards PRO performance. A slight increment in feed pressure buildup was found to be beneficial to water flux and power density up to 10.06 W m-2 without comprising the reverse salt flux. We believe this study may open up new perspectives on outer-selective PRO hollow fiber membranes and provide useful insights to understand and design next-generation outer-selective TFC hollow fiber membranes for osmotic power generation.

“…Ingole et al [30] have attempted to make the outer-selective TFC PRO hollow fiber membrane. Because of unsuitable interfacial polymerization conditions and substrates, their membranes could only achieve a peak power density of 1.62 W m -2 at 6 bar using 0.6 M NaCl and DI water as feeds.…”

“…The support layer of the membrane was a commercial polymer, polyethersulfone (PES), and the active layer was prepared using polyamide. According to Chou et al, Ingole et al (2014). The characterization of the membrane revealed that a thinner and smoother polyamide layer with a larger free volume was produced, which led to a higher water flux, better mechanical stability and greater power density than the existing membrane.…”

Pressure Retarded Osmosis (PRO) is a method for converting salinity gradients to power by allowing water to flow through a semi-permeable membrane against an applied hydraulic pressure. PRO already has a long history, starting from the middle of the last century, and has rapidly improved in recent years. In this paper, we present a historical development of PRO since its inception: the development of this renewable energy process has gone through several stages, depending on technological developments, worldwide energy demands, and environmental concerns. The technological progress of the process is also studied, as well as its cost viability and environmental impact. Finally, some ideas to further develop the PRO process and mitigate its detrimental effects are discussed.
