Pressure Retarded Osmosis (PRO): Past experiences, current developments, and future prospects
Desalination, 2016Abstract Pressure Retarded Osmosis (PRO) has attracted worldwide attention with respect to its salinity gradient energy production potential, and low energy desalination applications. PRO processes, which use Seawater Reverse Osmosis (SWRO) brine as draw solutions, have a higher potential of being applied to any new, and existing membrane based ...

Mass transport of various membrane configurations in pressure retarded osmosis (PRO)
Journal of Membrane Science, 2017Abstract Recent development of high performance membranes and advanced modeling have moved the pressure retarded osmosis (PRO) technology closer to commercialization. Nevertheless, a PRO model, that combines the aforementioned two aspects for mathematical quantification and comprehensive assessment of the multi-configured membranes, is still lacking.

A tool for assessing the scalability of pressure-retarded osmosis (PRO) membranes
Renewable Energy, 2020Abstract Osmotic energy recovery from hypersaline waters, such as produced water from oil and gas reservoirs and concentrated brine, is strategically significant to water utilization and sustainable energy production. Much attention has been given to pressure-retarded osmosis (PRO) as a potentially viable process for osmotic energy recovery.

Hydraulic Energy Generation for RO (Reverse Osmosis) from PRO (Pressure Retarded Osmosis)
2020 4th International Conference on Green Energy and Applications (ICGEA), 2020Although reverse osmosis (RO) is currently the most energy efficient, widely used, desalination technology, it still requires a great deal of energy to create the high pressure necessary to overcome the osmotic pressure of seawater. Pressure retarded osmosis (PRO), on the other hand, utilizes the salinity gradient between two solutions of different ...

Effect of Hydraulic Pressure on Organic Fouling in Pressure Retarded Osmosis (PRO) Process
Journal of the Korean Society of Water and Wastewater, 2015【Pressure retarded osmosis (PRO) process is one of membrane processes for harvesting renewable energy by using salinity difference between feed and draw solutions. Power is generated by permeation flux multiplied by hydraulic pressure in draw side. Membrane fouling phenomena in PRO process is presumed to be less sever, but it is inevitable.

PERFORMANCE EVALUATION OF PRESSURE RETARDED OSMOSIS (PRO) PROCESS FOR POWER GENERATION
2023Pressure retarded osmosis (PRO) process is an interesting membrane technology for alternative power generation operating based on difference in osmosis pressure between river water and seawater. Water from river having a low salinity permeates through a membrane to the other side where elevated pressure seawater having higher salinity flows.

Desalination, 2020
Abstract Pressure retarded osmosis (PRO) is an emerging technology capable of extracting energy from salinity gradients of wastewater paired with SWRO brine. However, this process's performance is hindered by irreversible biofouling due to bacteria-containing wastewater and the sponge-like support layer of PRO membranes.

Separation and Purification Technology, 2019
Abstract Pressure retarded osmosis (PRO) has been widely investigated to harness the osmotic energy from salinity gradient. Seawater desalination brine (SWBr) and wastewater retentate (WWRe) are employed as the draw and feed solutions respectively due to a large salinity difference between them and reuse of wastewater, but the fouling caused by WWRe ...
