Evoqua electrodialysis slashes energy use
Evoqua Water Technologies has launched an electrodialysis desalination system that has, according to the company, reduced energy costs by up to 30% in initial trials with the potential for even more.Evoqua's Nexed module technology includes innovative features such as a low-energy membrane, intelligent flow distribution, and tunable dissolved solids removal capability allowing new options for reduced energy use, costs, and facility footprint, the company said.
Nexed was introduced recently at Aquatech-Shanghai. Nexed modules will initially be used in brackish water desalination applications and will shortly be expanded to seawater desalination applications.
The product emerged from collaboration between Evoqua's Singapore and US research and development teams after its engineers achieved increased energy savings capabilities in the laboratory in 2008. Based on that finding, Evoqua won the Singapore Challenge competition initiated by the Singapore government.
