With reference now to the drawings, and in particular to FIGS. 1 through 5 thereof, a new water treatment device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 5, the aquarium water treatment device 10 generally comprises a housing 12 that has a top 14 and a bottom 16. The bottom 16 is closed and the top 14 is open. The top 14 and the bottom 16 are circular, such that the housing 12 is tubular. The housing 12 is transparent. The housing 12 has capacity of between 1 and 10 liters. Preferably, the housing 12 has capacity of between 2 and 7 liters. More preferably, the housing 12 has capacity of between 3 and 5 liters.
A partition 18 that has a border 20 complimentary to an inner perimeter 22 of the housing 12 is frictionally coupled to a wall 24 of the housing 12 proximate to the bottom 16. The partition 18 defines a lower chamber 26 and an upper chamber 28. Preferably, the border 20 is positioned adjacent to the bottom 16 and the partition 18 extends upwardly from the bottom 16, such that the lower chamber 26 is domed. The border 20 may be coupled to the inner perimeter 22. A plurality of penetrations 30 is positioned in the partition 18.
A pump 32, which is submersible, has an intake 34 that is positionable in an aquarium containing water requiring treatment. The pump 32 also has an outflow 36 that is fluidically connected to the lower chamber 26. A power cord 38 has a first end 40 and a second end 42. The first end 40 is operationally couple to the pump 32. A coupler 44 is coupled to a second end 42 of the power cord 38, such that the coupler 42 is configured to connect the pump 32 to a power source.
A pipe 46 is coupled to a center 48 of the partition 18. The pipe 46 extends upwardly to proximate to the top 14 of the housing 12. The pipe 46 is fluidically connected to the outflow 36 and the lower chamber 26. The outflow 36 comprises a hose 50 coupled to the pump 32. The hose 50 is positionable in the pipe 46, such that the hose 50 is positioned to direct output from the pump 32 through the pipe 46 to the lower chamber 26. The intake 34 comprises a tube 52 that extends laterally from the pump 32, such that the tube 52 is positionable along the bottom of the aquarium.
A support 54 is coupled to a wall 24 of the housing 12. The support 54 is coupled to the pipe 46, such that the pipe 46 is stabilized longitudinally relative to the housing 12. The support 54 is variably positionable from the top 14 and the bottom 16. The support 54 comprises a ring 58 that is complimentary to the pipe 46, such that the pipe 46 is insertable into the ring 58. Each of a plurality of laterals 60 is coupled to the ring 58 and extends to the wall 24, such that the laterals 60 frictionally engage the wall 24. Preferably, the plurality of laterals 60 comprises four laterals 60 positioned at 90 degrees around the ring 58. Each of the laterals 60 may be fixedly coupled to the wall 24. The ring 58 is positioned for insertion of the pipe 46 and the laterals 60 are positioned to engage the wall 24 such that the pipe 46 is stabilized longitudinally relative to the housing 12. Each of the plurality of laterals 60 may be fixedly coupled to the wall 12, such that the support 54 is fixedly positioned substantially equally from the top 14 and the bottom 16.
A nozzle 62 is positioned proximate to the top 14. The nozzle 62 is fluidically connected to the upper chamber 28, such that the nozzle 62 is positioned to allow water to flow from the upper chamber 28 into the aquarium.
The device 10 also includes a coagulation promoter 64 and a flocculation promoter 66. The coagulation promoter 64 may be inorganic. Preferably, the coagulation promoter 64 is selected from the group consisting of Al2O3, Al2(SO4)3(H2O)n, n=14-18, AlCl3 6H2O, Fe2(SO4)3 9H2O, FeCl3, and Na2Al2O4. The coagulation promotor 64 also could be organic, comprising, for example, polyacrylic acid-based polymers of polyacrylamide. The coagulation promoter 64 may be aqueous. Preferably, the coagulation solution 64 comprises aqueous Al2O3. The flocculation promoter 66 comprises a polyelectrolyte 88, which may be cationic, anionic, or non-ionic and are readily apparent and obvious to one skilled in the art. The flocculation promoter 66 may be aqueous.
A hanger 68 is coupled to an outside surface 70 of the housing 12 proximate to the top 14. The hanger 68 is configured to extend over the rim of the aquarium to prevent lateral movement of the housing 12 relative to the aquarium. The hanger 68 comprises a horizontal plate 72 coupled to the outside surface 70. A vertical plate 74 is coupled to the horizontal plate 72 distally from the outside surface 70. The vertical plate 74 extends downwardly toward the bottom 16 of the housing 12. The horizontal plate 72 is configured to extend over the rim of the aquarium with the vertical plate 74 configured to prevent lateral movement of the housing 12 relative to the aquarium. The hanger 68 is configurable to position the housing 12 on the exterior of the aquarium.
Each of a plurality of spigots 76 is positioned in the wall 24 and fluidically coupled to the upper chamber 28. The plurality of spigots 76 may comprise an upper spigot 78 positioned proximate to the top 14, a center spigot 80 positioned approximately equally from the top 14 and the bottom 16, and a bottom spigot 82 positioned proximate to the bottom 16. The upper spigot 78 is positioned substantially opposite the hanger 68 on the housing 12. The upper spigot 78, center spigot 80 and bottom spigot 82 are vertically aligned. Each spigot 76 comprises a handle 84 operationally coupled to a valve 86. The valve 86 can be opened using a respective handle 84 to drain sludge from the upper chamber 28 through a respective spigot 76 positioned in the wall 24.
In use, the pump 32 is configured to transfer water requiring treatment from an aquarium to the lower chamber 26. The coagulation promoter 64 and the flocculation promoter 66 can be added as required to the housing 12 such that solids in the water are induced by to form a sludge bed above and below the partition 18. The clarified water flows through the nozzle 62 back into the aquarium. Sludge can be drain from the housing 12 using the plurality of spigots 76.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
