Abstract

A water treatment system is disclosed. The water treatment system comprises a filter system, a filtered water tank in fluid communication with the filter system, and a water filtration cleaning system disposed between the filter system and the filtered water tank.

Claims (35)

1. A system, comprising:

a water filter system;

a filtered water tank in fluid communication with the water filter system; and

a water filtration cleaning system disposed about a combined inlet and outlet of the filtered water tank, wherein the water filtration cleaning system comprises a watertight vessel having a sealable opening configured to receive a sanitizing agent to clean or sterilize the filtered water tank.

2. The system of claim 1 , wherein the water filtration cleaning system comprises:

an inlet of the watertight vessel in fluid communication with the water filter system; and

an outlet of the watertight vessel in fluid communication with the filtered water tank.

3. The system of claim 2 , wherein the sealable opening comprises an access door attached to the watertight vessel.

4. The system of claim 3 , wherein the access door is configured to provide a watertight seal about the sealable opening in a closed position and access to an interior of the watertight vessel in an open position.

5. The system of claim 2 , wherein the water filtration cleaning system comprises a drain port disposed about the watertight vessel, wherein the drain port comprises a sealable opening configured to seal off or provide egress of fluid within the water tight vessel.

6. The system of claim 2 , wherein the water filter system comprises a multi stage filter system comprising a number of filters disposed in series, and wherein the inlet is connected to a final filter in the water filter system.

7. The system of claim 2 , wherein the water filter system comprises an integrated water purifier system, and wherein the inlet is connected to an exit of the integrated water purifier system.

8. A system, comprising:

a water filter system comprising an RO filter;

a filtered water tank in fluid communication with the water filter system; and

a water filtration cleaning system disposed about a combined inlet and outlet of the filtered water tank, wherein the water filtration cleaning system comprises a watertight vessel having a sealable opening configured to receive a sanitizing agent to clean or sterilize the filtered water tank.

9. The system of claim 8 , wherein the water filtration cleaning system comprises:

an inlet of the watertight vessel in fluid communication with the water filter system; and

an outlet of the watertight vessel in fluid communication with the filtered water tank.

10. The system of claim 9 , wherein the sealable opening comprises an access door attached to the watertight vessel.

11. The system of claim 10 , wherein the access door is configured to provide a watertight seal about the sealable opening in a closed position and access to an interior of the watertight vessel in an open position.

12. The system of claim 9 , wherein the water filtration cleaning system comprises a drain port disposed about the watertight vessel, wherein the drain port comprises a sealable opening configured to seal off or provide egress of fluid within the water tight vessel.

13. The system of claim 9 , wherein the water filter system comprises a multi stage filter system comprising a number of filters disposed in series, and wherein the inlet is connected to a final filter in the water filter system.

14. The system of claim 9 , wherein the water filter system comprises an integrated water purifier system, and wherein the inlet is connected to an exit of the integrated water purifier system.

15. A method, comprising:

positioning a water filtration cleaning system between a water filter system and a filtered water tank,

wherein the water filtration cleaning system comprises:

a watertight vessel comprising a sealable opening configured to receive a sanitizing agent to clean or sterilize the filtered water tank; and

receiving, by the watertight vessel, the sanitizing agent to clean or sterilize the filtered water tank.

16. The method of claim 15 , wherein the sealable opening comprises an access door attached to the watertight vessel.

17. The method of claim 16 , wherein the access door is configured to provide a watertight seal about the sealable opening in a closed position and access to an interior of the watertight vessel in an open position.

18. The method of claim 17 , further comprising:

opening the access door;

inserting, through the sealable opening, the sanitizing agent into the watertight vessel; and

closing, after inserting the sanitizing agent into the watertight vessel, the access door.
