Evoqua Commercializes Innovative Electrochemical Desalination Technology with First OEM Agreement

Evoqua Water Technologies has commercialized its innovative, optimized membrane electrochemical desalination technology for adjustable dissolved solids removal capability with its first OEM agreement.

The advanced, low-pressure electrodialysis membrane technology enables water output quality to be tuned by power adjustments to minimize footprint and energy consumption. In its first OEM agreement to license the technology, Evoqua will exclusively supply HydroNovation Inc. with a proprietary electrochemical cassette containing Evoqua’s newly developed ion-selective membranes for HydroNovation’s HydroDI “salt-free softeners” systems targeting residential point-of entry (POE) application and commercial applications such as food and beverage outlets.

Approximately 11 million traditional salt-based softeners in the United States each release about 500 pounds of salt into ground water annually. Salt discharge from water softeners is a growing issue in the US Southwest, other states and around the world.

The HydroDI System cost-effectively removes both hardness ions and other ions such as nitrates, lead and arsenic from water using electrical potential without the use of any chemicals resulting in bottled water quality from every tap in a home.

Evoqua will continue to develop the optimized electrochemical technology for the municipal, industrial brackish and seawater desalination markets. Research and development of the technology began in 2008 when Evoqua, then Siemens Water Technologies, won a global competition for a three-year matching grant funded by the Singapore Environmental Water Industry organization. The low pressure electrodesalination technology has since continued to be refined to progress to increasingly higher volumes of treatment capacity.

“The development of advanced, cost effective low-pressure membranes that can be modulated to produce tailored water quality is a significant step forward opening new desalination applications for water quality output,” said Paul O’Callaghan, BlueTech Research CEO and founder.

“Evoqua’s innovative, adjustable electrochemical desalination technology offers a highly flexible, cost-effective means to remove dissolved solids,” said Rodney Aulick, Evoqua senior vice president and Industrial Segment lead. “Commercialization of the technology marks a major milestone and we look forward to continuing to enhance the technology for a wide variety of markets where footprint and low energy consumption are at a premium.”

Evoqua’s innovative electrochemical desalination technology and other water treatment technologies for municipal, industrial and marine applications will be exhibited June 1-4 at the Singapore International Water Week booth B2–R18. For more information about commercial applications for the technology, contact Patrick Buzzell at [email protected].

We are reaching the end of the beginning with WebRTC, and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management. For example, if you have an existing service – possibly built on a variety of different PaaS/SaaS offerings – and you want to add real-time communications you are faced with a challenge relating to user management, authentication, authorization, and validation. Service providers will w...
The term culture has had a polarizing effect among DevOps supporters. Some propose that culture change is critical for success with DevOps, but are remiss to define culture.

There is no question that businesses successful in adopting a DevOps mindset have seen departmental culture change, ...

Fundamentally, SDN is still mostly about network plumbing. While plumbing may be useful to tinker with, what you can do with your plumbing is far more intriguing. A rigid interpretation of SDN confines it to Layers 2 and 3, and that's reasonable. But SDN opens opportunities for novel constructions in Layers 4 to 7 that solve real operational problems in data centers. "Data center," in fact, might become anachronistic - data is everywhere, constantly on the move, seemingly always overflowing. Net...

WebRTC defines no default signaling protocol, causing fragmentation between WebRTC silos. SIP and XMPP provide possibilities, but come with considerable complexity and are not designed for use in a web environment.
