Abstract

A system and method for remediating a body of water and collecting suspended and dissolved solids therefrom are provided. The system includes a water-impervious lining positionable in a depression in or adjacent a body of water. The lining and depression define a treatment vessel, which includes a treatment portion, an outlet portion for containing treated water, and an outflow weir between the treatment portion and the outlet portion. Water to be treated is transported from the water body to the treatment portion. An entrapment element is delivered and mixed into the transported water, the entrapment element for capturing suspended and dissolved solids in the transported water and effecting a separation between the captured solids and water cleansed therefrom. The captured solids can be removed from the treatment basin, and the cleansed water can move through a channel in the outflow weir into the outlet portion.

Claims (20)

1. A system for remediating a body of water and collecting suspended and dissolved solids therefrom, the system comprising:
a water-impervious lining positionable in a depression in or adjacent a body of water desired to be treated, the lining and depression defining at least a portion of a treatment vessel, the vessel comprising a treatment portion having an inlet for receiving water to be treated, an outlet portion for containing treated water, and an outflow weir between the treatment portion and the outlet portion, the outflow weir extending to a top end higher than a water surface, and extending across the vessel to side edges sealed against the opposed sides of the vessel;
means for transporting water to be treated from the water body to the treatment portion inlet;
means for delivering an entrapment element to the transported water and for mixing the entrapment element with the transported water, the entrapment element for capturing suspended and dissolved solids in the transported water and effecting a separation between the captured solids and water cleansed therefrom; and means for removing the captured solids from the treatment portion, the cleansed water movable through a channel in the outflow weir into the outlet portion.
2. The system recited in Claim 1, wherein the entrapment element delivering means comprises means for delivering a stream of bubbles into the water being transported upstream of an outlet end of the transporting means, the bubbles for capturing suspended and dissolved solids in the water and carrying them to the water surface, the bubbles and captured solids movable to the solids-removing means.
3. The system recited in Claim 2, wherein the mixing means comprises a cracking valve and a saturation tube upstream of the cracking valve and downstream of the bubble delivering means.
4. The system recited in Claim 1, wherein the entrapment element delivering means comprises a source of at least one of a coagulant and a flocculant, and means for injecting the at least one of the coagulant and the flocculant into the transported water.
5. The system recited in Claim 4, wherein the mixing means comprises a serpentine flow pathway upstream of the treatment portion.
6. The system recited in Claim 1, wherein the lining comprises a flexible sheeting positionable in a depression in soil adjacent the water body, the depression sloping downward in the treatment basin toward the inlet.
7. The system recited in Claim 6, wherein the sheeting comprises a geo-textile material.
8. The system recited in Claim 6, wherein the depression further has a pit therein adjacent the inlet, for collecting precipitated solids therein.
9. The system recited in Claim 1, further comprising an effluent pump having an inlet within the outflow portion and a float switch for activating the effluent pump when effluent in the outflow portion has reached a predetermined depth.
10. The system recited in Claim 1, wherein the lining comprises a structure positionable in the water body, and further comprising a flotation element positioned to retain the lining in a partially submerged orientation, a top edge of the vessel higher than a surface of the water body.
11. The system recited in Claim 10, wherein:
the structure is movable within the water body, and the water-transporting means has an aperture adjacent a forward portion of the structure, movement of the structure through the water body thereby causing water to flow into the aperture; and the mixing means comprises a portion of the transporting means describing a serpentine pathway.
12. The system recited in Claim 11, wherein the water-transporting means comprises a plurality of vertically oriented baffles positioned in spaced relation from each other, inner ends overlapping.
13. A method for remediating a body of water and collecting suspended and dissolved solids therefrom, the method comprising:
transporting water from a body of water to an inlet of a treatment vessel, the treatment vessel formed by a water-impervious lining positioned in a depression in or adjacent a body of water desired to be treated;
delivering an entrapment element to the transported water;
mixing the entrapment element with the transported water, the entrapment element for capturing suspended and dissolved solids in the transported water and effecting a separation between the captured solids and water cleansed therefrom;
channeling the mixed water and entrapment element to a treatment portion of the treatment vessel;
removing the captured solids from the treatment portion; and permitting the cleansed water to move into an outlet portion of the treatment vessel.
14. The method recited in Claim 13, wherein the entrapment element delivering step comprises delivering a stream of bubbles into the water being transported upstream of the treatment portion, the bubbles for capturing suspended and dissolved solids in the water and carrying them to the water surface.
15. The method recited in Claim 14, wherein the mixing step comprises channeling the water and bubbles to saturation tube and thence to a cracking valve.
16. The method recited in Claim 13, wherein the entrapment element delivering step comprises injecting at least one of a coagulant and a flocculant into the transported water.
17. The method recited in Claim 16, wherein the mixing step comprises channeling the water into a serpentine flow pathway upstream of the treatment portion.
18. The method recited in Claim 13, wherein the lining comprises a flexible sheeting positionable in a depression in soil adjacent the water body, the depression sloping downward in the treatment basin toward the inlet.
19. The method recited in Claim 11, wherein:
the water-transporting step comprises moving the vessel within the water body, so as to cause water to enter a forward-placed aperture in the vessel;
and the mixing step comprises channeling water entering the aperture through a serpentine pathway upstream of the treatment portion.
20. A method for constructing a water-remediation and solids-collection system comprising:
positioning a water-impervious lining in a depression in or adjacent a body of water desired to be remediated and from which solids are desired to be collected;
and positioning an outflow weir adjacent an outlet end of the vessel to extend to a top end at least as high as an intended level of water in the treatment vessel, and across the vessel to side edges sealed against the opposed sides of the vessel, the outflow weir and an outlet portion of the vessel sides containing the outlet end defining an outflow portion;
providing means for transporting water to be treated from the water body to a region of the treatment basin;
providing means for delivering and mixing an entrapment element into the water being transported upstream of an outlet end of the transporting means, the entrapment element for capturing suspended and dissolved solids in the transported water and effecting a separation between the captured solids and water cleansed therefrom;
providing means for removing the entrapment element and captured suspended solids from the treatment basin; and providing means for channeling the cleansed water out from the outflow basin.
