Abstract

The output of a mechanical/chemical water filter(s) is conveyed through tubes transparent to ultraviolet radiation disposed in proximity to a source of ultraviolet radiation having the capability of disinfecting the water flowing through the tubes. Each of the opposed ends of the tubes is supported within a cylindrical cavity of a support member and retained in sealed engagement by a tube circumscribing O-ring clamped about the tube by a plate detachably attached to the support member. Passageways within the support member channel the water into or out of the respective tube end. The source of ultraviolet radiation is secured to opposed support members in close proximity to the tubes to enhance the bacteria, virus and micro organism killing capability of the ultraviolet radiation source.

Claims

1. Apparatus for filtering and disinfecting a fluid flowing from a source of fluid to a discharge conduit, said apparatus comprising in combination:

a) filter means for filtering the fluid;

b) a source of ultraviolet light radiation for irradiating the fluid filtered by said filter means;

c) a tube for conveying the fluid past said source of ultraviolet radiation to irradiate the conveyed fluid, said tube having an inlet and an outlet;

d) a first support member for supporting said inlet, said first support member including a cavity for receiving said inlet to establish a junction between said inlet and said first support member, means circumscribing and adjacent to said inlet for sealing said junction and means for compressing said circumscribing means to form a seal at said junction and to prevent leakage of fluid between said first support member and said inlet, said compressing means having a substantially flat surface portion situated parallel to a flat portion of said first support member for forming said seal evenly;

e) a second support member for supporting said outlet, said second support member including a further cavity for receiving said outlet to establish a further junction between said outlet and said second support member, further means circumscribing and adjacent to said outlet for sealing said further junction and further means for compressing said further circumscribing means to form a further seal at said further junction and to prevent leakage of fluid between said second support member and said outlet, said further compressing means having a substantially flat surface portion situated parallel to a flat portion of said second support member for forming said further seal evenly;

f) means for conveying the fluid from said filter means to said inlet through said support member;

g) further means for conveying the irradiated fluid to the discharge conduit;

h) each of said first and second support members includes means for mounting said source of ultraviolet radiation therebetween and above said tube, said source of ultraviolet radiation comprises a tubular light and wherein said mounting means comprises a pair of opposed sockets for receiving said tubular light, and wherein double sided sticky tape is included for securing each socket of said pair of sockets to the respective one of said first and second support members;

i) a further tube for conveying the fluid past said source of ultraviolet radiation to irradiate the conveyed fluid, said further tube having a further inlet and a further outlet,

j) said second support member including means for supporting said further inlet comprising a yet further cavity for receiving said further inlet to establish a yet further junction between said further inlet and said second support member, yet further means circumscribing and adjacent to said further inlet for sealing said yet further junction and yet further means for compressing said yet further circumscribing means to form a seal at said yet further junction and to prevent leakage of fluid between said second support member and said further inlet, said yet further compressing means having a substantially flat surface portion situated parallel to a flat portion of said second support member for forming said seal evenly;

k) means for establishing fluid communication between said outlet and said further inlet;

l) said first support member including means for supporting said further outlet comprising a still further cavity for receiving said further outlet to establish a still further junction between said further outlet and said first support member, still further means circumscribing and adjacent to said further outlet for sealing said still further junction and still further means for compressing said yet further circumscribing means to form a seal at said still further junction and to prevent leakage of fluid between said first support member and said further outlet, said still further compressing means having a substantially flat surface portion situated parallel to a flat portion of said first support member for forming said seal evenly;

m) diameters of said tube and said further tube being substantially larger than a diameter of each of said means for conveying the fluid from said filter means to said inlet through said support member, means for establishing fluid communication between said outlet and said further inlet, and further means for conveying the irradiated fluid to the discharge conduit; and

n) a removable cover located above said source of ultraviolet light radiation, said tube and said further tube.

2. The apparatus as set forth in claim 1 wherein each of said circumscribing means, said further circumscribing means, said yet further circumscribing means and said still further circumscribing means comprises an O-ring, and wherein said compressing means and said still further compressing means comprises a first apertured plate for penetrably receiving said inlet and said further outlet, and means for securing said first apertured plate to said first support member and said further compressing means and said yet further compressing means comprises a second apertured plate for penetrably receiving said outlet and said further inlet and further means for securing said second apertured plate to said second support member.

3. The apparatus as set forth in claim 2 wherein each of said first and second support members includes means for mounting said source of ultraviolet radiation therebetween and equidistant and above said tube and said further tube, and wherein said source of ultraviolet radiation comprises a tubular light and wherein said mounting means comprises a pair of opposed sockets for receiving said light.
