Abstract

A apparatus and system for filtering wastewater from a basin is disclosed, wherein the apparatus prevents backflow of waste water, provides easy access for cleaning and replacing strainers, and a viewing window. The apparatus also provides additional ports for draining the apparatus.

First claim

I claim:

1. An apparatus for filtering liquid waste comprising:
A filter assembly body having a cavity for receiving liquid waste;
An access panel movably attached to the filter assembly body for movably covering and sealing a portion of the filter assembly body, wherein the access panel includes a window made of a clear material that provides a view within the cavity;
An input port removably connected to the filter assembly body, said input port having a first end and a second end, the first end of the input port being configured to receive the liquid waste;
A strainer configured to be received in the cavity of the filter assembly body and configured to strain the liquid waste, the second end of the input port being inserted into the strainer and configured to release the liquid waste into the strainer;
A main output port connected to the filter assembly body and the cavity of the filter assembly body; and
Wherein the access panel extends between the input port and the output port along a majority of a length of the filter assembly body.

2. The apparatus of claim 1 wherein the strainer includes a buoyant ball.

3. The apparatus of claim 1 wherein the strainer attaches to the access panel.

4. The apparatus of claim 1 further comprising an emergency output port for draining the cavity, the emergency output port having a valve.

5. An apparatus for filtering liquid waste comprising:
A filter assembly body having a cavity;
An input port removably connected to the filter assembly body and the cavity of the filter assembly body, said input port having a first end and a second end, the first end of the input port being configured to receive the liquid waste;
A filter configured to be received in the cavity of the filter assembly body to filter the liquid waste, the second end of the input port being inserted into the filter and configured to release the liquid waste into the filter;
A main output port connected to the filter assembly body and the cavity of the filter assembly body;
An emergency output port connected to the filter assembly body and the cavity of the filter assembly body for draining the cavity; and
An access panel removably attached to said filter assembly body for covering and sealing a portion of the cavity of the filter assembly body, the access panel including a window made of a clear material that provides a view within the cavity, wherein the access panel extends between the input port and the output port along a majority of a length of the filter assembly body.

6. The apparatus of claim 5 , wherein said access panel comprises a door movably secured to the filter assembly body.

7. The apparatus of claim 5 , wherein said access panel comprises a panel removably secured to the filter assembly body.

8. The apparatus of claim 5 , wherein said filter comprises a flange configured to receive the input port of the filter assembly.

9. The apparatus of claim 5 , wherein said filter is configured to be removably attached to said access panel.

10. The apparatus of claim 5 , wherein said filter comprises a flange configured to attach said filter to the input port of the filter assembly.

11. The apparatus of claim 10 , wherein said filter includes a ball valve disposed adjacent to said flanges.

12. The apparatus of claim 11 , wherein said ball valve comprises a ball movably contained within a ball cage including holes for filtering debris.

13. The apparatus of claim 12 , wherein said ball has a diameter larger than said filter connector.

14. The apparatus of claim 12 , wherein said ball is made of a buoyant material.

15. The apparatus of claim 12 , wherein said ball has a hollowed center.

16. The apparatus of claim 5 , wherein said emergency output port includes a valve.
