Jordan’s first SWRO opens for business
The opening of the first seawater reverse osmosis (SWRO) plant in Jordan marks a jumping off point for the country from which it can continue to develop a desalination programme, including the much-anticipated Red Sea-Dead Sea project.

The Long Read: Do we have the technology for potable water reuse?
Water reuse for drinking purposes is racing up the agenda in the US and elsewhere. Work to draw up new rules for potable reuse is advancing in states including California and Arizona, as well as in Canada and the European Union. Technologies are being piloted, and plants permitted.

Construction completed on Australia’s largest recycled water project
Wastewater reuse is a hot topic in Australia, with the “toilet-to-tap” label being trotted out on many occasions. In the state of Queensland, it has a lot more relevance because, as well as a brand new desalination plant at Gold Coast, the state now has a giant new municipal water reuse scheme. This article discusses…

Depth Exposed Membrane for Water Extraction (DEMWAX™)
DXV Water Technologies has designed a novel membrane system that uses natural pressure, a very low recovery rate and gravity flow of feedwater past the membrane surface, resulting in an elegant, efficient system. Since the invention of the reverse-osmosis (RO) membrane researchers have tried to harness natural water-pressure, but past attempts mimic onshore processes with…

Reclaiming the grass at Pebble Beach golf course
Tertiary treatment of wastewater has had a technology upgrade to improve play at Pebble Beach golf course, which recently hosted the US Open Championship. The problem was high sodium and total dissolved solids concentrations, and difficulties with reusing wastewater during low flows. Microfiltration followed by RO was selected to meet the water quality criteria. The…

Small-scale desalination approach to a big water problem
A research project recently undertaken at the Massachusetts Institute of Technology has revealed a new mechanism for desalination/purification of water, employing a microfluidic channel-network system, which could lead to the development of small and portable units. The authors have started to build a prototype device in the laboratory in order to demonstrate the necessary scale-up…
