Treatment Of Fluid Transport Conduit With Ultraviolet Radiation

A system, comprising:

• a fluid transport conduit;
• a plurality of ultraviolet radiation sources;
• a light guiding unit to direct ultraviolet radiation emitted from the plurality of ultraviolet radiation sources into the fluid transport conduit to irradiate internal walls of the fluid transport conduit for removing contaminants therefrom;
• a control unit to direct the plurality of ultraviolet radiation sources to emit a predetermined dosage of ultraviolet radiation to the internal walls of the fluid transport conduit via the light guiding unit for a predetermined duration;
• and
• a power source to provide power to the plurality of ultraviolet radiation sources and the control unit.

A system for disinfecting internal walls of a fluid transport conduit, comprising:

• a light guiding layer enclosing the fluid transport conduit, wherein the light guiding layer comprises a waveguide structure having an ultraviolet reflective layer, an ultraviolet extraction surface to diffusively scatter ultraviolet radiation from the light guiding layer, and an ultraviolet transparent layer formed between the ultraviolet reflective layer and the ultraviolet extraction surface;
• a plurality of ultraviolet radiation sources operatively coupled to the light guiding layer to direct ultraviolet radiation to the internal walls of the fluid transport conduit, wherein the light guiding layer directs ultraviolet radiation emitted from the plurality of ultraviolet radiation sources to ultraviolet transparent sections on an outer surface of the fluid transport conduit, the emitted ultraviolet radiation passing through the ultraviolet transparent sections, penetrating the fluid transport conduit and irradiating the internal walls;
• and
• a control unit to adjust a plurality of operating parameters of the plurality of ultraviolet radiation sources as a function of removal of contaminants from the internal walls of the fluid transport conduit, wherein the plurality of operating parameters include a duration that the ultraviolet radiation sources emit ultraviolet radiation, a dosage of ultraviolet radiation delivered by the ultraviolet radiation sources, and a power setting for operating the ultraviolet radiation sources.
