Experience helps boost production and stability at Ras Abu Jarjur
Improving production with reduced expenditure could be the main targets of any desalination facility around the world. Such feats are being methodically achieved at Ras Abu Jarjur reverse-osmosis (RO) plant in Bahrain as a result of a series of improvements. Of the many available desalination techniques, RO was seen from the earliest days as a…

Leveraging nanotechnology for next generation seawater desalination
NanoH2O advanced membranes for reverse osmosis (RO) desalination represent a new material that enhances current polymer-based membranes with the benefits of nanotechnology. These nanocomposite RO membranes represent a step-change in productivity through improved permeability while maintaining requisite salt and contaminant rejection. Since the original publication of this concept, further development and optimization of this membrane…

Combining Forward Osmosis with Reverse Osmosis
A combination of forward osmosis with reverse osmosis could facilitate the treatment of some high fouling wastewaters. The system uses brine to draw water from the wastewater without high pressure or turbulence. Key element is the membrane’s ability to allow rapid passage of water without much internal concentration polarization. The diluted draw solution can then…
