Results Positive for First Commercial UV-C LED Disinfection System

Aquionics’ prototype proves five times more efficient than conventional methods

Erlanger, Kentucky (October 5, 2011) – UV disinfection specialist Aquionics and LED expert Dot Metrics Technologies presented the results of their innovative UV LED based reactor design at the North American IUVA Conference (Toronto, ON). The results proved their UV LED disinfection system to be five times more efficient than conventional disinfection systems.

Aquionics’ and Dot Metrics’ new UV-LED disinfection system proved five times more efficient than conventional disinfection systems.

Aquionics’ and Dot Metrics’ new UV-LED disinfection system proved five times more efficient than conventional disinfection systems.

The results were obtained from studies conducted by University of North Carolina (Charlotte, N.C.) and University of Colorado (Boulder, Colo.). They show more than a 3 log reduction of E. coli at an optical power efficiency exceeding 10 gpm/ Watt. Conventional mercury based UV systems have yet to break the 2 gpm/ Watt peak performance level.

UV LEDs have proven effective in applications where UV disinfection was previously thought impossible. The process is mercury free, activated and deactivated in only nine nanoseconds, and operates using low voltage sources. Such benefits are a vast improvement over conventional disinfection methods, and make the new system prime for market adoption.

Aquionics and Dot Metrics Technologies anticipate the first in a series of products built around this new technology to be available in early 2012.

Aquionics and Dot Metrics Sign JDA to Combine Disinfection Technologies

Collaboration will produce unprecedented disinfection products

Erlanger, Kentucky (July 25, 2011) – UV disinfection specialist Aquionics has signed a Joint Development Agreement with LED expert Dot Metrics Technologies (Charlotte, N.C.) to develop a new line of UV-LED disinfection products. The agreement formalizes several months of working together to bring new disinfection systems to the market.

Aquionics and Dot Metrics have signed a Joint Development Agreement to combine efforts.

Dot Metrics is a small company associated with the University of North Carolina at Charlotte. It focuses on UV LED systems development for disinfection of water, air and surfaces. For several years, Dot Metrics has been testing and discovering new applications for UV LEDs.

UV treatment of fluids is replacing traditional chemical treatment in many applications, however it still has a number of drawbacks. UV LEDs overcome almost all the problems associated with standard, mercury-based UV disinfection.

“The joint development effort between Dot Metrics and Aquionics is a great example of a successful collaboration. Dot Metrics brings innovative UV LED expertise and Aquionics contributes its experience and resources to rapidly commercialize the technology and provide access to key markets,” said Dot Metrics President and CEO, Rosanna Stokes. “In addition, access to technology from Aquionics’ sister companies within the water and photonics industries provides a strong basis for a long term relationship. The combined results of our efforts will provide a novel, small footprint, non-mercury based UV disinfection system in the market.”

“The development of UV LED chips has progressed significantly in the last few years to allow commercial adoption. Dot Metrics brings added value in packaging the chips and configuring them in a usable system,” says Aquionics President, Oliver Lawal. “After months of collaboration, we are pleased to announce our formal agreement as we work together towards the completion of a remarkable new range of products.”
