Water transport in reverse osmosis membranes is governed by pore flow, not a solution-diffusion mechanism

Science Advances, 2023
We performed nonequilibrium molecular dynamics (NEMD) simulations and solvent permeation experiments to unravel the mechanism of water transport in reverse osmosis (RO) membranes.

Fouling in reverse osmosis membranes: monitoring, characterization, mitigation strategies and future directions.

Heliyon, 2023
Water scarcity has been a global challenge for many countries over the past decades, and as a result, reverse osmosis (RO) has emerged as a promising and cost-effective tool for water desalination and wastewater remediation.

The open membrane database: Synthesis–structure–performance relationships of reverse osmosis membranes

Journal of Membrane Science, 2022
Since the advent of thin-film composite polyamide membranes brought forth a breakthrough in desalination and water purification membranes nearly half a century ago, recent years have only witnessed marginal improvements in the water-salt selectivity of ...

Reverse osmosis membrane biofouling: causes, consequences and countermeasures

npj Clean Water, 2022
Biofouling has been referred to as “the Achilles heel” of reverse osmosis (RO) membrane technology; the main cause being polyamide RO membranes lack of chlorine tolerance. Biofouling increases the operating cost of water treatment by increasing RO system

Modeling micropollutant removal by nanofiltration and reverse osmosis membranes: considerations and challenges.

Water Research, 2022
Organic micropollutants (OMPs) in drinking water constitute a potential risk to human health; therefore, effective removal of these pollutants is required.

Tutorial review of reverse osmosis and electrodialysis [PDF]

Journal of Membrane Science, 2021
Reverse osmosis (RO) and electrodialysis (ED) are the two most important membrane technologies for water desalination and treatment. Their modes of operation and transport mechanisms are very different, but on a closer look also have many similarities ...

3E assessment of a solar-driven reverse osmosis plant for seawater desalination in a small island of the Mediterranean Sea

Energy Reports, 2023
Water scarcity in many regions of the world and global demographic growth make the desalination of seawater and/or brackish an effective solution to meet the growing demand for fresh water.

Cost of fouling in full-scale reverse osmosis and nanofiltration installations in the Netherlands

Desalination, 2021
The economic impact of fouling in spiral wound membranes is not yet well explored. There has been an established assumption that the cost of fouling in membrane processes is significant, but this hypothesis has not been thoroughly evaluated. We conducted
