UV Pearl a UVC LED based Water Disinfection System

Dot Metrics Technologies, North Carolina, United States


The UV Pearlâ„¢ is the worlds most energy efficient UV water disinfection system, proven to be over 20 times more efficient than existing commercial disinfection systems. A novel design enables the UV Pearl to provide more disinfection using less UV than traditional systems, allowing the use of low power UV-LEDs.

Primary Application Area: Environmental, Water & Waste

Technology Development Status: Commercial Product

Technology Readiness Level: TRL 8


Value Proposition: In addition to being the worlds most efficient water disinfection system, Dot Metrics system offers additional technology drivers over the current state of the art. Our product is mechanically robust, has a small and scalable footprint, allows multi-wavelength sources, is mercury-free, instant on/off, chemical free, and produces no by-products.

Government Funding/Support to Date: Federal funding for the development of Dot Metrics water disinfection technology came from the National Science Foundation (NSF)SBIR program. Dot Metrics received a Phase I SBIR (award number IIP-0740524 )in January 2008 in the amount of $99,887. Additional funds for this program were obtained through the state of North Carolina's ONE North Carolina SBIR/STTR Matching Funds Program in the amount of $74,915 which resulted in Dot Metrics receiving Phase IB supplemental funding to the original Phase I SBIR int he amount of $37,448. In February 2009 Dot Metrics received a Phase II SBIR grant (award number IIP-0848759)from the National Science Foundation. The Phase II grant enabled Dot Metrics to obtain several Research Experience for Undergraduate Grants from NSF. Upon obtaining outside funding from commercialization partner Aquionics Dot Metrics was able to secure a Phase IIB supplement from the National Science Foundation yielding a cumulative funding amount for the Phase II and Phase IIB programs of $1,094,163 (award number IIP-0848759). The Phase IIB grant expires in June 2014.
