IPC: C02F1/32

Abstract: A UVC disinfection system is described where incoming fluid, such as water, is directed onto a transparent window in a vertical disinfection chamber. The incoming water is directed downward by a channel at an acute angle (e.g., 10-20 degrees) with respect to a central axis of the disinfection chamber and impinges on the window at an angle almost perpendicular to the window surface. One or more UVC LEDs are optically coupled to the window. The water impinging on the window becomes agitated due to the severe redirection and interaction with water already in the chamber. This randomizes (mixes) the water in the area where there is the highest UVC power. The UVC LEDs direct light along the central axis of the cylindrical chamber for maximum exposure of the water to the UVC light. Disinfection efficiency is therefore increased.
