Evoqua Launches Electrochemical Desalination Technology

Evoqua Water Technologies has launched the next generation in electrochemical desalination that utilizes tunable technology that can reduce energy costs by as much as 30% in initial trials, with the potential for even more.

The new Nexed module technology provides features such as an advanced low-energy membrane, intelligent flow distribution and tunable dissolved solids removal capability allowing new options for reduced energy use, costs and facility footprint. This technology was introduced at Aquatech-Shanghai, the largest water technology event in Asia. The modules will initially be used in brackish water desalination applications and will shortly be expanded to seawater desalination applications.

Nexed modules provide cost-effective treatment options such as consistent water quality with variable feed water parameters or partial removal of contaminants without the need for blending. Because output quality can be manipulated by input power adjustments, this feature also allows for options to minimize footprint and provide for optimized energy consumption.

“Our Nexed system represents a breakthrough in electrochemical desalination,” said Ron Keating, Evoqua Water Technologies CEO. “Through our R&D efforts we have been able to bridge major technology gaps to make low-cost, effective and reliable desalination possible as well as lay the groundwork for even larger breakthroughs to come.

Through a collaborative project between Evoqua’s Singapore and U.S. R&D teams, engineers achieved new energy savings capabilities in a lab setting in 2008 which led to Evoqua winning the “Singapore Challenge” competition initiated by the country’s government. Since then, Evoqua has been developing a commercial version of its process which was launched at the event.
