Osmosis is the movement of solvent across a membrane induced by a solute-concentration gradient. It is very important for cell biology. Recently, it has started finding technological applications in the emerging processes of Forward Osmosis and Pressure-Retarded Osmosis. They use ultrathin and dense membranes supported mechanically by much thicker porous layers. Until now, these processes have ...

Pressure retarded osmosis has the potential to utilize the free energy of mixing when fresh river water flows into the sea for clean and renewable power generation. Here, we present a systematic investigation of the performance limiting phenomena in pressure retarded osmosis--external concentration polarization, internal concentration polarization, and reverse draw salt flux--and offer insights...

An excessive amount of renewable energy could be possibly produced when solutions dissimilar salinities are combined simultaneously in a semipermeable membrane. The aforestated harnessing for transformation into power achieved through the pressure retarded osmosis (PRO) process. PRO system utilizes membrane separating low concentration solution from pressurized-high concentrated solution. This ...

Osmosis is a physical phenomenon that has been extensively studied by scientists in various disciplines of science and engineering. Early researchers studied the mechanism of osmosis through natural materials, and from the 1960s, special attention has been given to osmosis through synthetic materials. Following the progress in membrane science in the last few decades, especially for reverse osm...

The gain in net power produced by Salinity Gradient plants river mouths due to the optimal location of water intakes is analysed this paper. More precisely, work focuses on stratified and membrane-based technology Pressure-Retarded Osmosis. A methodology for analysis proposed then applied a case study Colombia. Temperature, salinity discharge data were gathered at Magdalena mouth develop hydrod...
