STW and Sunstone join to market zero discharge technology
Water management firm, STW Water Process and Technologies, has expanded its role in its exclusive agreement with Sunstone Water Group to commercialize Sunstone's patented wastewater effluent treatment technology to provide direct potable reuse (DPR) in municipal markets.
Solar electrodialysis brings water to off-grid villages
A simple set of solar panels and a battery system connected to an electrodialysis desalination unit could provide fresh water for a typical Indian village according to researchers at the Massachusetts Institute of Technology (MIT) in the US.
Australia and NZ ferry RO units to Tuvalu
Australia and New Zealand are leading an urgent response to the drought currently afflicting the South Pacific islands of Tuvalu and Tokelau by transporting reverse-osmosis (RO) units to provide a water supply.
Aqua-Chem RO and distillers help US aid effort in Japan
A combination of mobile reverse-osmosis (RO) and ship-based RO and distillation plants all made by Aqua-Chem Inc is helping provide water for victims of the Japanese earthquake and tsunami.
RO units diverted from Bermuda to Haiti
Two reverse-osmosis (RO) desalination units scheduled for a client in Bermuda have been diverted for Haiti earthquake disaster relief by Florida-based Water Treatment Systems Inc (WTS).
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 of this technology. If developed, this type of portable, self-powered desalination system would find many important applications such as for disaster relief, military use, shipboard units and regional water purification in developing countries.
