Abstract

A fluid filtration system is shown. The fluid filtration system utilizes a one-piece or multiple piece containers having a plurality of radiation-transmissible media adapted to receive light, such as ultraviolet light, white light or other wavelength light. The radiation-transmissible media are situated in the container and at least one or a plurality of radiation sources, such as ultraviolet lamps, are situated in an array in proximity to the radiation-transmissible media. The radiation-transmissible media interrupts the flow and velocity of the fluid stream passing through the container to extend the duration of radiation for any contaminants and also provide enlarged surface areas for the contaminants to be received and ultimately exposed to the radiation. In one example, the radiation-transmissible media may be tubular or spherical sections that are hollow or solid and made of quartz.

First claim

What is claimed is:

1. A fluid sterilization system comprising:
a container;
radiation-transmissible media situated in said container; and
a radiation source;
said radiation-transmissible media being adapted to provide both mechanical filtration by physically capturing organisms as they are carried through the container in a fluid stream and substantially simultaneously permitting transmission of radiation from said radiation source through said radiation-transmissible media, said radiation being an appropriate amount to disinfect said fluid stream and at least one surface of said radiation-transmissible media;
said radiation-transmissible media comprising a plurality of discrete and individual media that are either randomly situated and distributed or arranged in a non-random or predetermined order in said container and confined by said container;
wherein said container lies in a first imaginary plane, said radiation source comprises a plurality of ultraviolet lamps arrayed in a linear pattern in a second imaginary plane within or adjacent to said container; said system further comprising:
a mobile housing adapted to house said container containing said radiation source and said plurality of said radiation-transmissible media;
said mobile housing having at least one fan or blower and a controller for controlling operation of said at least one fan or blower and said radiation source.

2. The fluid sterilization system as recited in claim 1 wherein said radiation-transmissible media comprises at least one of quartz media, glass or polymer.

3. The fluid sterilization system as recited in claim 1 wherein said radiation-transmissible media comprises quartz media.

4. The fluid sterilization system as recited in claim 3 wherein said container comprises a plurality of said quartz media.

5. The fluid sterilization system as recited in claim 4 wherein said plurality of said quartz media comprises different predetermined shapes.

6. The fluid sterilization system as recited in claim 4 wherein said plurality of said quartz media comprises generally the same predetermined shape.

7. The fluid sterilization system as recited in claim 6 wherein said predetermined shape is at least one of a circular shape, a cylindrical shape, a spherical shape, or a polygonal shape.

8. The fluid sterilization system as recited in claim 6 wherein said predetermined shape is a hollow or solid shape.

9. The fluid sterilization system as recited in claim 7 wherein said predetermined shape is a hollow or solid shape.

10. The fluid sterilization system as recited in claim 7 wherein said container comprises a plurality of said quartz media.

11. The fluid sterilization system as recited in claim 6 wherein said predetermined shape is coated or doped with at least one of an ultraviolet emission material or a fluorescent material.

12. The fluid sterilization system as recited in claim 1 wherein said radiation source is at least one of white light or an ultraviolet radiation source.

13. The fluid sterilization system as recited in claim 1 wherein said radiation source is an ultraviolet radiation source.

14. The fluid sterilization system as recited in claim 1 wherein said at least one of a size of said media or a number of said media are selected in response to a velocity of said fluid stream through said container.

15. The fluid sterilization system as recited in claim 1 wherein said container is generally planar and lies in a first imaginary plane, said radiation source comprises a plurality of ultraviolet lamps arrayed in a linear pattern in a second imaginary plane above said container.

16. The fluid sterilization system as recited in claim 15 wherein said first and second imaginary planes are generally parallel.

17. The fluid sterilization system as recited in claim 2 wherein said radiation-transmissible media comprises a plurality of media, each of which are generally the same size.

18. The fluid sterilization system as recited in claim 2 wherein said radiation-transmissible media comprises a plurality of media having different sizes or dimensions.

19. The fluid sterilization system as recited in claim 3 wherein at least one of a size or amount of said radiation-transmissible media is adapted to at least one of vary a path of said fluid stream, disrupt said fluid stream, or slow a velocity of said fluid stream.

20. The fluid sterilization system as recited in claim 1 wherein said container is a one-piece construction that houses both said radiation-transmissible media and said radiation source.

21. The fluid sterilization system as recited in claim 1 wherein said container is adapted to receive said radiation-transmissible media and a second member comprises a frame that receives and supports said radiation source.

22. The fluid sterilization system as recited in claim 21 wherein said second member is adjacent to said radiation-transmissible media either upstream or downstream of said radiation-transmissible media.

23. The fluid sterilization system as recited in claim 1 wherein said mobile housing comprises a housing having at least one locator frame for removably locating said container to a desired position in said housing such that said radiation-transmissible media interrupts a fluid stream.

24. The fluid sterilization system as recited in claim 1 wherein said radiation-transmissible media is substantially transparent to light.

25. The fluid sterilization system as recited in claim 1 wherein each of said plurality of discrete and individual media being tubular and having a wall having an inner surface and an outer surface, said inner surface defining a hollow passageway.

26. A filtration assembly for use in a fluid filtration system, said filtration assembly comprising:
a container; and
radiation-transmissible media situated in said container;
said container being adapted to be situated in said fluid filtration system in proximate relationship to a radiation source to provide both mechanical filtration by physically capturing organisms as they are carried through the container in a fluid stream and substantially simultaneously permitting transmission of radiation from said radiation source through said radiation-transmissible media, said radiation being an appropriate amount to disinfect said fluid stream and at least one surface of said radiation-transmissible media;
said radiation-transmissible media comprising a plurality of discrete and individual media that are either randomly situated and distributed or arranged in a non-random or predetermined order in said container and confined by said container;
wherein said fluid filtration system comprises:
a mobile housing adapted to receive and house said container, said mobile housing being moveable by hand and containing a plurality of ultraviolet lamps arranged in a second imaginary plane such that they become operatively associated with said container after said container is mounted in said mobile housing;
said mobile housing further comprising:
at least one fan or blower for generating said fluid stream through said mobile housing; and
a controller for controlling operation of said at least one fan or blower and said plurality of ultraviolet lamps.

27. The filtration assembly as recited in claim 26 wherein said radiation-transmissible media comprises at least one of quartz media, glass or polymer.
