We will report on a record performance of an all-LED point-of-use water disinfection system that utilizes our deep UV LED lamps with peak emission wavelengths in the range from 270 nm to 280 nm. Results of water disinfection experiments demonstrated reduction of E. coli bacteria concentration by 5.5 LOG for 0.5 liter/min flow and 3 LOG reduction for 2 liter/min. These results demonstrate a great potential of DUV LEDs for water disinfection, primarily in low-flow, point-of-use and consumer oriented applications.
