Evoqua pilot shows electrochemical modules viable

Evoqua has completed a pilot of its Nexed electrochemical desalination modules at the Brackish Groundwater National Desalination Research Facility in Alamogordo, New Mexico.

The pilot tested a variety of brackish water feed sources provided by the research facility. Its findings, according to Evoqua, demonstrated the viability of the company’s electrochemical desalination technology across the range of brackish sources. The results have led Evoqua to develop a larger pilot using production Nexed modules that can be utilized to demonstrate the technology at facilities across the world, the company said.

Nexed modules are already the foundation of a 2 Ml/d desalination demonstration facility nearing completion in Tuas Singapore. Evoqua is working with Singapore’s national water agency, PUB, to build the new desalination facility. The facility is nearing completion and staged increases in flow rate will be achieved through 2017 after the first 90 m³/d system is installed in early-2016.

According to Evoqua, more than 80% of municipal drinking water systems in the US serve a population base using this amount of output.

The Brackish Groundwater National Desalination Research Facility is the focal point for developing technologies for the desalination of brackish and impaired groundwater found in the inland states. It houses researchers from other federal government agencies, universities, the private sector, research organizations, and state and local agencies to work collaboratively and in partnership toward improving our nation’s water resources.
