A Review of CFD Modelling and Performance Metrics for Osmotic Membrane Processes

open access: yesMembranes, 2020
Simulation via Computational Fluid Dynamics (CFD) offers a convenient way for visualising hydrodynamics and mass transport in spacer-filled membrane channels, facilitating further developments in spiral wound membrane (SWM) modules for desalination ...

Modeling and Optimization of Membrane Process for Salinity Gradient Energy Production

open access: yesSeparations, 2021
When hydraulic pressure was added on the feed side of the membrane in the otherwise conventional pressure retarded osmosis (PRO) process, the production rate of the salinity gradient energy could be significantly increased by manipulating the hydraulic ...

Modern Use of Water Produced by Purification of Municipal Wastewater: A Case Study

open access: yesEnergies, 2021
All the urban areas of developed countries have hydric distribution grids and sewage systems for collecting municipal wastewater to treatment plants. In this way, the municipal wastewater is purified from human excreta and other minor contaminants while ...

Comparative evaluation of osmotically-driven cleaning methods for organic-inorganic fouling in pressure retarded osmosis (PRO)

open access: yesEngineering Science and Technology, an International Journal, 2018
Pressure retarded osmosis (PRO) is a promising technique of desalination techniques. However, one of the major problems is permeate flux decline by fouling.

Mass Transport in Osmotically Driven Membrane Processes

open access: yesMembranes, 2021
Forward osmosis (FO) and pressure retarded osmosis (PRO) are the two operational modes for osmotically driven membrane processes (ODMPs). ODMPs have gained increasing popularity in the laboratory over the years; however, OMDPs have not been applied in ...

Investigation of the fouling effect on a commercial semi-permeable membrane in the pressure retarded osmosis (PRO) process [PDF]

open access: yesSeparation and Purification Technology, 2018
Abstract One of the main challenges for generating osmotic power by using PRO technology is the membrane fouling which reduces the permeate flux and consequently increases the cost and decreases the osmotic power generation. In this research, different feed waters with various qualities were used to investigate the effect of fouling on a commercial ...

Sustainable Design and Synthesis of Hybrid RO-PRO Systems for Industrial Wastewater Treatment

open access: yesChemical Engineering Transactions, 2017
Pressure retarded osmosis (PRO) is a new technology can provide sustainable power to many processes. However, the optimal design methods of integrating this technique in practical processes are rarely reported in literatures.

Aspects of Mathematical Modelling of Pressure Retarded Osmosis

open access: yesMembranes, 2016
In power generating terms, a pressure retarded osmosis (PRO) energy generating plant, on a river entering a sea or ocean, is equivalent to a hydroelectric dam with a height of about 60 meters.

Stand-alone seawater RO (reverse osmosis) desalination powered by PV (photovoltaic) and PRO (pressure retarded osmosis) [PDF]

open access: yesEnergy, 2015
Abstract A novel RO seawater desalination plant powered by PV (Photovoltaic) and PRO (PVROPRO) is proposed and the feasibility of two stand-alone schemes, SSRO (salinity-solar powered RO) operation and SRO (salinity powered RO) operation, are investigated. First, the stand-alone feasibility of the plant is thermodynamically analysed.

Novel Thermal Desalination Brine Reject-Sewage Effluent Salinity Gradient for Power Generation and Dilution of Brine Reject

open access: yesEnergies, 2020
Salinity gradient resource presents an essential role for power generated in the process of pressure-retarded osmosis (PRO). Researchers proposed several designs for coupling the PRO process with the desalination plants, particularly reverse osmosis ...
