Abstract

Water treatment apparatus including an elongated first water chamber, an inlet for water at one end of the chamber, an outlet for water at the opposite end of the chamber and at least one ultraviolet lamp within and extending longitudinally of the chamber. The chamber may be connected to a second chamber into which air and/or ozone may be introduced through outlets for flow through the second chamber. Alternatively, the first chamber may comprise a chamber which contains the air and/or ozone outlets. A funnel shaped member is provided at the upper end of the first or second chamber to collect bubbles carrying impurities in the water to the surface.

Claims

1. Water treatment apparatus comprising:

an elongated first water treatment chamber,

an inlet for water to be treated at one end of said chamber,

an outlet for treated water at the opposite end of said chamber, and

at least one elongated ultraviolet lamp, said lamp extending longitudinally within said chamber wherein water flowing through said chamber from said inlet to said outlet is exposed to ultraviolet light from said lamp.

2. Water treatment apparatus as claimed in claim 1 wherein said first water chamber is arranged in a substantially upright attitude and wherein said one end of said chamber comprises a lower end of said chamber and wherein the opposite end of said chamber comprises an upper end of said chamber, said lamp being arranged centrally in said chamber.

3. Water treatment apparatus as claimed in claim 2 and including a second water treatment chamber, said outlet from said first chamber being connected to an inlet to said second chamber and means for exposing said water in said second chamber to ozone and/or air.

4. Water treatment apparatus as claimed in claim 3 wherein said second chamber is disposed in a substantially upright attitude and wherein said inlet to said second chamber is disposed at an upper end of said second chamber and said second chamber having an outlet at a lower end thereof.

5. Water treatment apparatus as claimed in claim 4 and including an ozone and/or air outlet or outlets at the lower end of said second chamber for supplying ozone and/or air to said chamber for the passage of ozone and/or air through water in said second chamber.

6. Water treatment apparatus as claimed in claim 5 and including collecting means at the upper end of said second chamber for collecting foam at or adjacent the surface of water therein created by air and/or ozone passing through said second chamber and a waste outlet connected to said collecting means.

7. Water treatment apparatus as claimed in claim 6 wherein said collecting means comprises a funnel having an upper edge over which foam may pass into the interior of said funnel.

8. Water treatment apparatus as claimed in claim 6 and including a float for supporting said foam collecting means member at or adjacent said surface of water.

9. In combination, water treatment apparatus as claimed in claim 4 and a reservoir for containing water to be treated, first connecting means connecting said inlet to said first chamber and second connecting means connecting said outlet from said second chamber to said reservoir.

10. The combination of claim 9 and including means for introducing air into said second connecting means for assisting flow of water from said second chamber into said reservoir.

11. Water treatment apparatus as claimed in claim 2 and including an ozone and/or air outlet or outlets at the lower end of said chamber for supplying ozone and/or air to said chamber for the passage of ozone and/or air therethrough.

12. Water treatment apparatus as claimed in claim 11 and including collecting means at the upper end of said chamber for collecting foam at or adjacent the surface of water therein created by air and/or ozone passing through said chamber and a waste outlet connected to said collecting means.

13. Water treatment apparatus as claimed in claim 12 wherein said collecting means comprises a hollow conical member having an upper edge over which foam may pass into the interior of said hollow member.

14. Water treatment apparatus as claimed in claim 12 and including a plurality of ultraviolet lamps arranged around said collecting means.

15. In combination, water treatment apparatus as claimed in claim 12 and a reservoir for containing water to be treated, first connecting means connecting said inlet to said first chamber and second connecting means connecting said outlet to said reservoir.

16. Water treatment apparatus for treating water in a reservoir, said water treatment apparatus comprising:

a substantially upright elongated first water treatment chamber, an inlet for water to be treated at a lower end of said chamber, first connecting means for connecting said inlet to said reservoir, an outlet at the upper end of said first chamber, at least one elongated ultraviolet lamp, said lamp extending longitudinally within said first chamber,

a substantially upright second water chamber, said outlet from said first chamber being connected to an inlet to said second chamber at an upper end of said second chamber,

an ozone and/or air outlet or outlets at the lower end of said second chamber for supplying ozone and/or air to said chamber for the passage of ozone and/or air through water in said second chamber,

collecting means at the upper end of said second chamber for collecting foam at or adjacent the surface of water therein created by air and/or ozone passing through said second chamber,

a waste outlet connected to said collecting means,

an outlet for treated water at a lower end of said second chamber, and second

connecting means for connecting said outlet of said second chamber to said reservoir for returning treated water to said reservoir.

17. Water treatment apparatus as claimed in claim 16 wherein said second connecting means returns treated water from said second chamber to said reservoir at a position above said inlet to said first chamber.

18. Water treatment apparatus as claimed in claim 17 and including means for introducing air into said second connecting means for assisting flow of water from said second chamber into said reservoir.
