The National Science Foundation (NSF) has granted a $475,000 Small Business Innovation Research (SBIR) Phase II award to Sensor Electronic Technology. The award was granted to manufacture point-of-use (POU) drinking water disinfection solutions based on deep ultraviolet LED (DUV LED).
UVCLEAN LED Lamps
Sensor Electronic, for the SBIR program, will design, manufacture and exhibit sophisticated all-LED water treatment devices that consume less power and have high-reliability. The main focus of the project will be on decreasing the LED disinfection system’s cost and enhancing the germicidal efficiency, through advancements in the disinfection chamber design and LED packaging.
Using the SBIR Phase I Award, Sensor Electronic demonstrated 99.99% E-coli disinfection in a POU drinking water solution, with the water flowing at a speed of one liter every minute. The company demonstrated the disinfection by utilizing the 275nm UVCLEAN LED lamps that emitted an approximate optical power of 30 mW.
Developing the UV disinfection technology by utilizing semiconductor UV lights will use unique device aspects such as compact size and ruggedness, high-reliability, low-power consumption, swift switching time, and controlled UV spectral power distribution. These advantages will facilitate the inclusion of UV disinfection units into water purification systems.
