Due to a variety of factors, the water in many water-holding structures, including recreational water basins, becomes contaminated from the introduction of oil-based substances. Examples include swimming pools, wading pools, hot tubs and spas. The oil-based substances may include pump oil, suntan oil/lotion and body oils excreted from people who enter the water. Due to the nonpolar nature of many such oil-based substances and the specific gravity thereof, these impurities are typically immiscible with water and form a thin layer at the surface of the water. These characteristics make it difficult to remove them from the water. Importantly, in addition to being unhygienic and diminishing the appearance of the water, suntan oils, body oils and the like can form a coat of film on a water filtration component and potentially clog and/or reduce the useful lifetime of such filtration means.
Some systems for removing oils from pool water have been reported, including those disclosed in U.S. Pat. No. 7,037,038 to Haski et al., U.S. Pat. No. 6,372,472 to Nehls et al., U.S. Pat. No. 5,980,761 to Boissie et al., U.S. Pat. No. 5,820,758 to Dale et al., U.S. Pat. No. 5,676,839 to Shippert and U.S. Pat. No. 3,868,319 to Black et al., each of which is incorporated by reference herein in its entirety to the extent non inconsistent herewith. While there may be some utility in these systems, they each possess certain drawbacks and/or undesirable features. A need therefore exists for an improved oil removal system for pools and the like.
Embodiments of a floating absorption apparatus of the present invention generally include a container for an absorbent material, wherein the container is adapted and configured to float in water and comprises one or more orifices that allow the water to enter the container, come into contact with the absorbent material contained therein, and exit the container. In one aspect, the absorbent material may comprise a foam that is formulated to absorb nonpolar substances, such as oils and organic liquids, e.g., solvents.
For a more complete understanding of the present invention, reference is now made to the accompanying drawing, in which:
The exemplary embodiments are best understood by referring to the drawings, like numerals being used for like and corresponding parts of the various drawings. In the following description of embodiments, orientation indicators such as “top,” “bottom,” “up,” “down,” “upper,” “lower,” “front,” “back,” etc. are used for illustration purposes only; the invention, however, is not so limited, and other possible orientations are contemplated.
Referring to
In one embodiment, a container 2 comprises a lid 12 that can be opened to allow for insertion of the oil-absorbent material 6 therein and closed to allow for containment of the oil-absorbent material 6 there within. In other embodiments (not shown), a container 2 may comprise other means for insertion into and removal therefrom of the oil-absorbent material 6, as would be understood by one skilled in the art. In one embodiment, a container 2 may comprise a mechanism for securing a lid 12 in a closed position. In the embodiment depicted in
In one embodiment, an oil-absorbent material 6 may comprise a foam material. In other embodiments, the oil-absorbent material 6 may comprise any suitable material known to absorb oils and/or other substantially nonpolar substances, as would be understood by one skilled in the art. In one embodiment, the foam material 6 may comprise a microcellular, open-cell foam. In one embodiment, the foam material 6 may comprise the E-FoM™ product available from Lone Magnolia Technologies, LLC, D/B/A Lone Magnolia Technology™. In one embodiment, the foam material 6 possesses anti-microbial properties. In one embodiment, the foam material 6 is resistant to fungus, mold and/or mildew growth.
In one aspect, the foam material 6 may be constructed such that after it has adsorbed a quantity of nonpolar substance(s), it may be manipulated (e.g., squeezed, rinsed, etc.) to remove/extract some or substantially all of the nonpolar substance(s), such that the foam material 6 may be reused for absorption purposes. In one embodiment, the foam material 6 may be constructed such that it floats in water. In one embodiment, the foam material 6 may be utilized in the present invention “as is,” while in other embodiments (not shown) the foam material 6 may be disposed within one or more protective casings (e.g., sleeves) that are at least partially water permeable.
In operation, an embodiment of a floating oil absorption apparatus 100 of the present invention may be equipped with one or more oil-absorbent materials 6. In one embodiment, once the oil-absorbent material-equipped floating oil absorption apparatus 100 is provided, a lid 12 is closed and secured in a closed orientation utilizing a latch 14 and keeper 16. In one embodiment the closed-lid floating oil absorption apparatus 100 is introduced to a water environment, such as, but not limited to, a swimming pool. Once the user believes that the floating oil absorption apparatus 100 has removed a sufficient amount of nonpolar substance(s) from the water environment, the floating oil absorption apparatus 100 may be removed from the water environment, wherein the lid 12 is opened and one or more of the one or more oil-absorbent materials 6 may be removed from the floating oil absorption apparatus 100. Once the user has removed any of the oil-absorbent materials 6 from the floating oil absorption apparatus 100, such oil-absorbent material(s) 6 may be manipulated to remove some or substantially all of the absorbed nonpolar substance(s) therefrom, as described herein and as would be understood by one skilled in the art. The removed oil-absorbent material(s) 6 may be reintroduced into the floating oil absorption apparatus 100 for further use or discarded, as appropriate. In one aspect, the floating oil absorption apparatus 100 may be removed from the water environment to remove one or more of the oil-absorbent material(s) 6 therefrom, or the oil-absorbent material(s) 6 may be removed therefrom while the floating oil absorption apparatus 100 remains in the water environment.
An exemplary method utilizing an embodiment of a floating oil absorption apparatus of the present invention comprises:
A Floating Oil Absorption Apparatus Provision Step, comprising providing a floating oil absorption apparatus, such as floating oil absorption apparatus 100;
An Oil-Absorbent Material Provision Step, comprising providing at least one oil-absorbent material, such as oil-absorbent material 6, at least partially within the floating oil absorption apparatus;
Floating Oil Absorption Apparatus Water Introduction Step, comprising providing the floating oil absorption apparatus equipped with the oil-absorbent material(s) to a water environment; and
A Floating Oil Absorption Apparatus Operation Step, comprising operating the oil-absorbent material(s)-equipped floating oil absorption apparatus by allowing it to float in the water environment.
Optionally, one or both of the following steps may be performed:
A Floating Oil Absorption Apparatus Restoration Step; comprising removing at least one oil-absorbent material from the floating oil absorption apparatus, removing at least some of the absorbed nonpolar material therefrom, and reintroducing the oil-absorbent material back into the floating oil absorption apparatus; and/or
A Floating Oil Absorption Apparatus Replacement Step, comprising removing at least one oil-absorbent material from the floating oil absorption apparatus, and introducing a different oil-absorbent material into the floating oil absorption apparatus to replace the removed oil-absorbent material(s)
The foregoing methods are merely exemplary, and additional embodiments of utilizing a floating oil absorption apparatus of the present invention consistent with the teachings herein may be employed. In addition, in other embodiments, one or more of these steps may be performed concurrently, combined, repeated, re-ordered, or deleted, and/or additional steps may be added.
The foregoing description of the invention illustrates exemplary embodiments thereof. Various changes may be made in the details of the illustrated construction and process within the scope of the appended claims by one skilled in the art without departing from the teachings of the invention. The present invention should only be limited by the claims and their equivalents.
