Multistage Pressure-Retarded Osmosis

Journal of Non-Equilibrium Thermodynamics, 2016
AbstractOne promising sustainable energy source is the chemical potential difference between salt and freshwater. The membrane process of pressure-retarded osmosis (PRO) has been the most widely investigated means to harvest salinity gradient energy. In this report, we analyse the thermodynamic efficiency of multistage PRO systems to optimize energy ...

Integrating Pressure-Retarded Osmosis and Membrane Distillation

, 2019
Exploring new technology to produce renewable energy has received more attention in recent years. A hybrid process of pressure-retarded osmosis (PRO) coupled with membrane distillation (MD) has been proposed as one of the alternatives for fossil fuels. The former process is used for energy production and the latter is appropriate for thermal separation

Membranes for power generation by pressure-retarded osmosis

Journal of Membrane Science, 1981
Abstract A model has been developed for obtaining the projected performance of membranes in pressure-retarded osmosis (PRO) from direct osmosis and reverse osmosis measurements. The model shows that concentration polarization within the porous substrate of the membrane markedly lowers the water flux under PRO conditions. The model has been used along

Salinity-gradient power: Evaluation of pressure-retarded osmosis and reverse electrodialysis [PDF]

Journal of Membrane Science, 2007
A huge potential to obtain clean energy exists from mixing water streams with different salt concentrations. Two membrane-based energy conversion techniques are evaluated: pressure-retarded osmosis and reverse electrodialysis.

Forward osmosis and pressure retarded osmosis process modeling for integration with seawater reverse osmosis desalination

Desalination, 2020
Osmotically driven membrane processes such as forward osmosis and pressure retarded osmosis may hold key advantages when integrated with seawater reverse osmosis to form hybrid FO-RO and RO-PRO systems.

Pressure-Retarded Osmosis Thermosyphon

Journal of Solar Energy Engineering, 2018
The basis of a novel method for passive solar water heating homologous to the traditional thermosyphon but driven by salinity gradient induced by changes of salinity gradient induced by evaporation at the collector is outlined. Its purpose, likewise than a thermosyphon, is to simplify the transfer of liquid while avoiding the cost and complexity of a ...

Power Generation With Pressure Retarded Osmosis

Volume 6A: Energy, 2013
Energy can be generated from two streams of different salt concentration using the osmotic pressure difference. Different methods have been proposed to harvest this energy. Pressure retarded osmosis (PRO) is investigated as a viable method and most promising technology. In PRO process, pure water permeates through a semi permeable membrane from the low
