Heat powered water pump for reverse osmosis desalination

Glushenkov M., Bhosale R., Kumar A., AlMomani F., Kronberg A., Qatar University, QA

Reverse osmosis (RO) is one of the most widely employed technologies for water desalination. A drawback of this technology is high consumption of electricity by electric motors used for high-pressure water pumping. Energy consumption can [...]

Low-cost membranes for nanofiltration and reverse osmosis

Berland B., Huntley K., Misra M., ITN Energy Systems, US

ITN has developed a proprietary nanocomposite membrane that outperforms state of the art water filtration and purification membranes by combining the following attributes: • High Salt Rejection • High water flux at Low Pressure • [...]

Effect of Support Structure on Permeance of Thin Film Composite Membranes

Ponnuru K., Lin H., Furlani E.P., SUNY-Buffalo, US

The production of potable water has become a worldwide concern to meet the demand of a growing population. The reverse osmosis (RO) membrane is the leading technology for desalination installations to produce drinkable water, due [...]

Computer modeling of water and salt transport in RO membrane active layers

Pitera J.W., Na Y.-H., Vora A., Dubois G., IBM Research, US

As part of a combined computational and experimental effort to develop new reverse osmosis desalination membrane materials, we have carried out detailed equilibrium and nonequilibrium molecular dynamics simulations of the aromatic polyamide active layers of [...]

Advanced RO Membrane Technology Based on Scientific Research for Seawater and Brackish water Desalination

Kimura M., Sasaki T., Henmi M., Toray Industries,Inc., JP

RO membrane technologies have made great progress in last 50 years. In seawater and brackish water desalination field, both energy saving and water quality improvement have been two major subjects. Advanced membranes are still demanded [...]
