Abstract
A system for treating a medium, such as water, with ultraviolet light is provided. The system can include an ultraviolet treatment chamber that is shaped to reduce reflections of the ultraviolet light within the ultraviolet treatment chamber and/or improve absorption of the ultraviolet light by the medium. Furthermore, the system can add an agent to the medium within the treatment chamber to further treat one or more contaminants that may be present within the medium. Still further, additional treatment, such as filtering the medium with a permeable material can be implemented within the treatment system.
Claims20
A system for treating a medium, the system comprising:
- a first ultraviolet source;
- and
- a shaped treatment chamber, wherein the shaped treatment chamber defines an interior comprising:
- a first portion from which ultraviolet light emitted by the first ultraviolet source enters the shaped treatment chamber;
- and
- a second portion fluidly attached to the first portion, wherein an area of a cross-section of the second portion substantially parallel to the first portion increases with distance from the first portion such that the second portion approximately conforms to at least one of:
- an unobstructed space emission pattern of the first ultraviolet source or a flow absorption distance dependence from the first ultraviolet source of the medium.
A system for treating a medium, the system comprising:
- an ultraviolet treatment chamber through which the medium moves;
- an ultraviolet source, wherein the ultraviolet source emits ultraviolet light into the ultraviolet treatment chamber;
- an agent source, wherein the agent source introduces an agent for treating the medium within the ultraviolet treatment chamber;
- and
- a computer system configured to implement a method of treating the medium by:
- determining at least one of:
- a level of contamination of the medium or a type of contamination of the medium;
- and
- operating the ultraviolet source and the agent source based on the at least one of:
- the level of contamination of the medium or the type of contamination of the medium to treat the medium in the ultraviolet treatment chamber by concurrently introducing the agent and emitting the ultraviolet light.
A system for treating a medium, the system comprising:
- an ultraviolet treatment chamber;
- an ultraviolet source, wherein the ultraviolet source emits ultraviolet light into the ultraviolet treatment chamber;
- an outer treatment chamber encapsulating the ultraviolet treatment chamber, wherein the medium first enters the outer treatment chamber and wherein at least a portion of at least one wall of the ultraviolet treatment chamber is permeable to allow filtered medium to pass there through into the ultraviolet treatment chamber;
- and
- an outlet located within the ultraviolet treatment chamber, wherein the medium exits the ultraviolet treatment chamber and the outer treatment chamber via the outlet.
