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

Evoqua’s new Nexed™ module technology provides innovative 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 new gold-standard in electrochemical desalination was introduced this week at Aquatech-Shanghai, the largest water technology event in Asia. Nexed 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 tunable feature also allows for options to minimize footprint and provide for optimized energy consumption. The base technology has proven unique features, including: low pressure, quiet operation, and tunable performance; and lays the groundwork for even more benefits in the future.

“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.

“By overcoming the challenges to make the technology adjustable for the end user, output quality can be manipulated by input power adjustments. This tunable feature also allows for options to minimize footprint and provide for optimized energy consumption. Nexed modules can be applied to a wide range of uses, including sea and brackish water, variable salinity applications, and water re-use options,” said Keating.
