Sensor Electronic Technology, Inc. Wins NSF SBIR Phase II Award to Develop Water Disinfection Units Based on DUV LEDs
Sep 16, 2010 Sensor Electronic Technology, Inc. (SETI), announced that is has been awarded a Small Business Innovation Research (SBIR) Phase II award from the National Science Foundation (NSF) for $475,000 to develop point-of-use (POU) Deep Ultraviolet LED (DUV LED) based drinking water disinfection systems.
During this SBIR program, SETI will design, develop, fabricate and demonstrate advanced all-LED water treatment units with reduced power consumption and extended reliability. The main effort will focus on increasing the germicidal efficacy and reducing the cost of LED disinfection units through the advances in LED packaging and disinfection chamber design.
Through Phase I of this NSF SBIR program, SETI recently demonstrated 99.99% disinfection of E-coli in a POU drinking water system with water flowing at 1 liter per minute using its 275nm UVCLEAN LED lamps emitting around 30mW of optical power.
