Abstract:
1. A fluid purification system, comprising: a fluid flow conduit; a light-emitting diode (LED) light source emitting ultraviolet light within the fluid flow conduit, wherein the ultraviolet light has a peak wavelength between about 265 nm and about 400 nm; a photo-catalytic material disposed within the fluid flow conduit, wherein the photo-catalytic material is positioned within an illumination area provided by the LED light source; and a continuous helical light reflector disposed within the fluid flow conduit and positioned within the illumination area provided by the LED light source to reflect the light emitted by the LED light source, wherein the light reflector is shaped and positioned to cause turbulent flow of fluid through the fluid flow conduit, and wherein the light reflector extends into the fluid flow conduit to cover between 20%-80% of a cross-sectional area of the fluid flow conduit.
