Filtration system for pet water fountain
A filtration system for a pet water fountain is provided. The filtration system utilizes a pump placed within or along a watering bowl. The water filtration system also utilizes a multi-stage filtering device. In one aspect, the multi-stage filtering device includes a first filtering stage representing copper zinc alloy particles, and a second filtering stage representing granulated activated carbon particles. Each stage may constitute filtering material that is separated into an array of cells residing along a vertical frame or is separated into stages placed in series within a tubular cartridge. A method for filtering water in a pet fountain is also provided herein.
1. A pet water fountain comprising:
a basin configured to hold a volume of water accessible to a domesticated pet;
a pump having a pump inlet and a pump outlet, the pump residing in a portion of the basin and being configured to circulate water within the basin when activated;
tubing connected to the pump outlet; and
a filtering device configured to filter water during circulation, wherein the filtering device comprises a tubular pouch, wherein a first filtration stage and a second filtration stage together reside in the tubular pouch, the tubular pouch residing in a tubular body, a first porous screen covering a first open end of the tubular body, a second porous screen covering a second opposite open end of the tubular body, wherein the first and second porous screens maintain the tubular pouch in place within the tubular body during water circulation, wherein the tubular body is disposed within the tubing connected to the pump outlet.
2. The pet water fountain of claim 1 , wherein:
the domesticated pet is a dog or a cat;
the pump is a submersible pump; and
the pump resides within the basin.
3. The pet water fountain of claim 1 , wherein:
the first filtration stage of the filtration device comprises copper alloy particles; and
the second filtration stage of the filtration device comprises granulated activated carbon particles.
4. The pet water fountain of claim 3 , wherein:
the first filtration stage and the filtration second stage reside near the pump outlet.
5. The pet water fountain of claim 3 , wherein:
the copper alloy is a copper zinc alloy;
the tubular pouch is in fluid communication with the pump outlet; and
a third porous screen separates the first stage and the second stage.
6. The pet water fountain of claim 5 , wherein:
the tubular pouch holds at least two first stage filtration compartments and at least two second stage filtration compartments, with the first and second stage filtration compartments alternating in series.
