Abstract

An underwater filtration operator which can be suspended in a river, lake, pond or other water body to filter water from the water body. The underwater filtration operator may be electrically charged to discharge impurities in the water body and increase filtering efficiency and the operator includes a housing having a selected configuration and divided into one or more filtration units, each of which includes a filter medium for filtering water from the water body. A pump is provided in the housing for receiving the filtered water from the filtration units and pumping the filtered water to a collection tank or dispenser or directly to an end user or to a reverse-osmosis water filtration unit for further filtration.

Claims

1. An underwater filtration operator for filtering water in a water body, comprising:

a housing;

a plurality of filtration units provided in said housing;

at least one filter provided in each of said plurality of filtration units, respectively, for receiving the water from the water body;

a pump chamber provided in said housing for receiving the water from said plurality of filtration units, respectively; and

a water pump provided in said pump chamber for pumping the water from the water body into said housing, through said filtration units and said filter and into said pump chamber.

2. The underwater filtration operator of claim 1 wherein said at least one filter comprises a pair of filters provided in radially adjacent relationship with respect to each other in said plurality of filtration units, respectively.

3. The underwater filtration operation of claim 1 comprising a housing flotation collar provided on said housing for floating said housing in the water body.

4. The underwater filtration operator of claim 3 wherein said at least one filter comprises a pair of filters provided in radially adjacent relationship with respect to each other in said plurality of filtration units, respectively.

5. The underwater filtration operator of claim 1 comprising at least one water inlet screen grid provided in said housing for receiving water from the water body and wherein said water inlet screen grid is charged with electricity.

6. The underwater filtration operator of claim 5 wherein said at least one filter comprises a sand filter and a second filter provided in radially adjacent relationship with respect to said sand filter in said plurality of filtration units, respectively.

7. The underwater filtration operator of claim 5 comprising a housing flotation collar provided on said housing for floating said housing in the water body.

8. The underwater filtration operator of claim 7 wherein said at least one filter comprises a sand filter and a second filter provided in radially adjacent relationship with respect to said sand filter in said plurality of filtration units, respectively.

9. The underwater filtration operator of claim 1 comprising a raw water chamber provided in said housing for receiving the raw water from the water body.

10. The underwater filtration operator of claim 9 wherein said at least one filter comprises at least one pair of water inlet screen grids provided in radially spaced-apart relationship with respect to each other and filter medium disposed between said water inlet screen grids in said plurality of filtration units, respectively.

11. The underwater filtration operator of claim 10 wherein at least one of said water inlet screen grids is charged with electricity.

12. The underwater filtration operator of claim 11 comprising a housing flotation collar provided on said housing for floating said housing in the water body.

13. The underwater filtration operator of claim 9 wherein at least one filter comprises a sand filter and a charcoal filter.

14. The underwater filtration operator of claim 11 wherein a first one of said water inlet screen grids encloses a sand filter and a second one of said screen grids encloses a charcoal filter provided in radially adjacent relationship with respect to said sand filter in said plurality of filtration units, respectively.

15. The underwater filtration operator of claim 14 comprising a housing flotation collar provided on said housing for floating said housing in the water body.

16. The underwater filtration operator of claim 1 wherein said at least one filter comprises at least one sand filter and a charcoal filter provided in radially adjacent relationship with respect to each other in said plurality of filtration units, respectively.

18. The underwater filtration operator of claim 17 wherein said at least one filter comprises a pair of filters provided in adjacent relationship with respect to each other in said plurality of filtration units, respectively.

19. The underwater filtration operator of claim 17 comprising a source of compressed air provided in pneumatic communication with said pump chamber for selectively introducing compressed air into said pump chamber and forcing the water from said pump chamber, through said at least one filter and into the water body and cleaning said at least one filter.

17. An underwater filtration operator for filtering water in a water body, comprising:

a housing charged with electricity;

a plurality of filtration units provided in said housing;

at least one filter provided in each of said plurality of filtration units, respectively, for receiving the water from the water body;

a pump chamber provided in said housing for receiving the water from said plurality of filtration units and said filter, respectively; and

a water pump provided in said pump chamber for pumping the water from the water body into said housing, through said filtration units and said filter and into said pump chamber.

20. An underwater filtration operator for filtering water in a water body, comprising:

a housing charged with a positive charge of electricity;

a plurality of filtration units provided in said housing, with at least one of said filtration units charged with electricity;

at least one filter provided in said plurality of filtration units, respectively, for receiving the water from the water body;

a pump chamber provided in said housing for receiving the water from said plurality of filtration units, respectively;

a water pump provided in said pump chamber for pumping the water from said housing through said filtration units and said filters and into said pump chamber;

a source of compressed air provided in pneumatic communication with said pump chamber for selectively introducing compressed air into said pump chamber and forcing the water from said pump chamber, through said at least one filter and into the water body and cleaning said at least one filter; and

a disinfectant manifold extending into said housing for introducing disinfectant into the water in said housing.
