PUB Singapore and Evoqua MOU for Developing Electrochemical Desalination Technology

Singapore’s national water agency PUB and Evoqua Water Technologies have agreed to a memorandum of understanding (MOU) to further develop electrochemical desalination technology that aims to improve energy and cost efficiencies in seawater desalination.

Evoqua, which has been presently engaged in a demonstration with PUB of initial feasibility of advanced electrochemical desalination technology, will now explore the design, construction, installation and evaluation of a system comprising Evoqua E-Desal equipment to produce drinking water from seawater with an eventual capacity of one U.S. million gallons per day (MGD).

PUB and Evoqua will commission the initial phase of the demo project by Dec. 31, 2014. The MOU will be signed at the Singapore International Water Week Desalination and Water Reuse Business Forum at 2 p.m. June 4 in Basement 2, Expo Hall D.

“R&D has been, and will continue to be vital to PUB, and collaborations with international partners such as Evoqua Water Technologies will help us co-create solutions that ensure our water supply remains sustainable and affordable,” said Harry Seah, PUB chief technology officer. “We look forward to working with Evoqua Water Technologies to further develop electrochemical desalination technology and achieve higher energy and cost efficiencies in this area.”

“The next phase of our relationship with PUB Singapore is the natural evolution of our commitment to further developing this promising electrochemical desalination technology,” said Rodney Aulick, Evoqua senior vice president of products and technology. “The MOU is also the latest milestone in our EDsalination technology which recently was commercialized with its first OEM agreement.”

Evoqua announced on May 21 that it will exclusively supply HydroNovation Inc. with a proprietary electrochemical cassette containing Evoqua’s newly developed ion-selective membranes for Hydronovation’s HydroDI “saltless softeners” systems targeting residential and commercial point-of entry (POE) applications such as food and beverage outlets.

Evoqua’s advanced, low-pressure electrodialysis membrane technology enables water output quality to be tuned by power adjustments to minimize footprint and energy consumption. 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 Programme Office. The low pressure electrodesalination technology has since continued to be refined to progress to increasingly higher volumes of treatment capacity.

The company, which traces its roots back more than a century through industry-leading brands such as Wallace & Tiernan® chlorination products, will continue to develop the optimized electrochemical technology for the municipal, industrial brackish and seawater desalination markets.

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.

About PUB Singapore

PUB, Singapore’s national water agency, is a statutory board under the Ministry of the Environment and Water Resources. It is the water agency that manages Singapore’s water supply, water catchment and used water in an integrated way.

PUB has ensured a diversified and sustainable supply of water for Singapore with the Four National Taps (local catchment water, imported water, NEWater, desalinated water).

To provide water for all, PUB calls on all to play our part to conserve water, keep our water catchments and waterways clean and build a relationship with water so we can enjoy our water resources. If we all play our part, we can have enough water for all our needs – for industry, for living, for life.
