Abstract

Provided is a filter apparatus, comprising two or more filter cartridges having a first end with an inlet and screen and a second end with an outlet and screen, and walls to contain a filter media held in a housing for holding the two or more filter cartridges in about the same orientation, and an attachment clamp connected to the housing. Also provided is a housing for holding two or more filter cartridges in about the same orientation and a method of using the filter apparatus and housing.

Claims (34)

1. A filter apparatus, comprising:

two or more filter cartridges each having a first end with an inlet and a first screen, a second end with an outlet and a second screen, and walls configured to contain a filter media;

a housing comprising an upper plate and a lower plate oriented substantially parallel to each other and configured to hold the two or more filter cartridges in about the same orientation, the upper plate and the lower plate each defining two or more openings to which the two or more filter cartridges are rotatably coupled; and

an attachment clamp connected to the housing,

wherein the two or more filter cartridges extend through the two or more openings, the upper plate, and the lower plate.

2. The filter apparatus of claim 1 , wherein the housing further comprises one or more support elements connecting the upper plate and the lower plate.

3. The filter apparatus of claim 2 , wherein the attachment clamp is connected to one or more of the one or more support elements.

4. The filter apparatus of claim 2 , wherein the one or more support elements comprise a combination of rods and support plates.

5. The filter apparatus of claim 1 , wherein the attachment clamp is a pole clamp.

6. The filter apparatus of claim 1 , wherein the walls configured to contain the filter media comprise a cartridge tube.

7. The filter apparatus of claim 6 , wherein the cartridge tube is transparent.

8. The filter apparatus of claim 6 , wherein the inlet includes an inlet connector and the outlet includes an outlet connector.

9. The filter apparatus of claim 8 , wherein the outlet connector is connected to the cartridge tube by an outlet flange.

10. The filter apparatus of claim 9 , wherein the outlet flange is conical.

11. The filter apparatus of claim 10 , wherein the inlet connector is connected to the cartridge tube by an inlet flange.

12. The filter apparatus of claim 1 , wherein the filter media comprises activated carbon.

13. The filter apparatus of claim 12 , wherein the filter media is hydrogel coated activated carbon.

14. The filter apparatus of claim 1 , wherein the walls configured to contain the filter media define a cylindrical shape.

15. A filter apparatus, comprising:

two filter cartridges each having a first end with an inlet comprising an inlet connector connected to a cartridge tube by an inlet flange and a first screen and a second end with an outlet comprising an outlet connector and connected to the cartridge by a conical outlet flange and a second screen, and a transparent cartridge tube configured to contain a filter media;

a housing comprising an upper plate and a lower plate oriented substantially parallel to each other and configured to hold the two filter cartridges in about the same orientation, the upper plate and the lower plate each defining two openings to which the two filter cartridges are rotatably coupled;

support elements comprising support plates and rods connecting the upper plate to the lower plate; and

a pole clamp connected to the support plates,

wherein the two filter cartridges extend through the two openings, the upper plate, and the lower plate.

16. The filter apparatus of claim 15 , wherein the filter media comprises activated carbon.

17. The filter apparatus of claim 15 , wherein the cartridge tubes are comprised of a transparent material selected from the group consisting of a polysulfone, a polycarbonate, a polypropylene and an acrylic.

18. A housing comprising:

a connected structure comprising an upper plate and a lower plate oriented substantially parallel to each other and configured to hold two or more filter cartridges in about the same orientation, the upper plate and the lower plate each defining two or more openings configured to receive the two or more filter cartridges and configured to rotatably engage the two or more filter cartridges;

one or more support elements connecting the upper plate and the lower plate; and

an attachment clamp connected to the housing,

wherein the two or more filter cartridges extend through the two or more openings, the upper plate, and the lower plate.

19. The filter apparatus of claim 1 , wherein the attachment clamp is rotatably coupled to the housing.

20. The filter apparatus of claim 15 , wherein the pole clamp is rotatably coupled to the support plates.

21. The housing of claim 18 , wherein the attachment clamp is rotatably coupled to the housing.
