Reverse Osmosis–Pressure Retarded Osmosis hybrid system: Modelling, simulation and optimization

Desalination, 2016
Abstract Theoretical analysis of energy harvesting from concentrated brine of Sea Water Reverse Osmosis (SWRO) system using Pressure Retarded Osmosis (PRO) is presented in this research. The mathematical model of SWRO–PRO hybrid system components such as SWRO unit, Energy Recovery Device (ERD), PRO unit and other auxiliary units were discussed.

Does Pressure-Retarded Osmosis Help Reverse Osmosis in Desalination?

Industrial & Engineering Chemistry Research, 2021
In a recent study [Parra, A. Ind. Eng. Chem. Res. 2019, 588 3060−3071], the design of reverse osmosis (RO) systems for desalination of water at different concentrations was studied and optimal solu...

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 ...

Three pressure retarded osmosis processes

IDA Journal of Desalination and Water Reuse, 2014
AbstractPressure retarded osmosis (PRO) processes can be implemented on a number of water types, using different technologies and achieving various power outcomes. The first one is seawater with river water, necessitating movement at seawater level of huge water volumes with extremely low power losses.

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

Pressure-retarded osmosis for enhanced oil recovery

Desalination, 2020
Abstract Pressure-retarded osmosis (PRO) is a membrane-based process that has been used historically to harness the osmotic energy of saline feed solutions. While conventional PRO applications target seawater (SW) /freshwater solution pairings, this paper focuses on an innovative high salinity gradient PRO application for waterflooding (WF) in the ...

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

Water flux in Pressure Retarded Osmosis

Desalination, 2015
Abstract The transport of water through a semipermeable membrane in Pressure Retarded Osmosis (PRO) has been considered. The water flux is believed to consist of two components. The water flux from feed to draw solution is due to the difference in the water concentrations of feed and draw solutions.
