Definitions
- the present invention relates generally to remediation of contamination in
- aquatic environments and more particularly, to an apparatus, system and method for remediation of contamination in aquatic environments.
- Manufacturing facilities may use water from natural sources, e.g., rivers and streams, for cooling plant processes.
- the water often contains entrained silt or other contaminants, that may be carried into the plant along with the water, even though wire mesh screens may be used to filter the water brought into the plant.
- the entrained silt or other contaminants may accumulate in conduits, e.g., pipes, sluices, weirs, or spillways used to carry the water, particularly as the water leaves the plant, because the flow may be slowest where the water is returned to its original source, and entrained silt and contaminants are more likely to deposit in the conduits when the flow becomes slower where the water exits the plant. This may result in a build-up of silt or other contaminants in the conduits where the water exits the plant that must be periodically remediated.
- a first aspect of the present invention provides an apparatus, comprising: a
- the vessel including an opening, wherein when the opening is facing a bottom of a body of water, and the vessel is in direct physical contact with the bottom of the body of water, wherein the vessel has been configured to contain and suspend materials inside the vessel; and an uptake line coupled to the vessel and configured to transport the contained and suspended materials from an interior of the vessel to an exterior of the vessel, wherein the uptake line includes an attachment selected from the group consisting of an impeller and a sliding collar.
- a second aspect of the present invention provides an apparatus, comprising: a vessel including an opening, wherein the opening is facing a bottom of a body of water, and the vessel is in direct physical contact with the bottom of the body of water, wherein the vessel has been configured to contain and suspend materials interior the vessel; and an uptake line coupled to the vessel and configured to transport the contained and suspended materials from an interior of the vessel to an exterior of the vessel.

- the metal may be stainless steel, copper, aluminum or alloys of steel, copper or aluminum.
- the plastic may be polyvinyl chloride, polycarbonate, high density polyethylene, high density
- polypropylene polyimide, silicone rubber, and the like.
- the uptake line 62 may be a metal or plastic tube slidably coupled to a lateral wall 45 of the vessel 10 by a slidable coupling 50.
- the slidable coupling 50 may be a compressible collar that exerts a frictional resistance to movement against a surface 60 of the uptake line 62, and against a surface 65 of the wall 45, so the uptake line may be vertically positioned along a longitudinal axis 70, by overcoming the frictional resistance to movement, thus moving the vessel 10 in one of the directions depicted by the bidirectional arrow 75.
- slidingably coupled is defined as a mechanical or physical coupling that may be formed or de-coupled by re-establishing or overcoming the frictional resistance to movement, thus holding the vessel 10 in place, or moving the vessel 10 in one of the directions depicted by the bidirectional arrow 75.
- re-establishing or overcoming the frictional resistance to movement when the compressible collar exerts frictional resistance to movement against the surface 60 of the uptake line 62, and against a surface 65 of the wall 45.
- the uptake line 62 has been equipped with a water or air impeller 5 for withdrawing water and suspended materials such as silt from the sediment layer at the bottom 35 of the body of water 40.
- the water or air impeller 5 may be a water or air booster cannon or a pump, so that the contained and suspended materials 20 may be transported from an interior 25 of the vessel to an exterior 30 of the vessel 10.
- the vessel 10 may be configured with 360° directional underwater propulsion units 17 so that the opening 15 of the apparatus 100 may be geographically located over the bottom 35 of the body of water 40, e.g. over selected polar coordinates of the bottom 35 of the body of water 40.
- the vessel 10 may be "lowered” into position by mechanical or other means, in accordance with the step 620 of the method 600, as described in US Patent 7264713, issued September 4, 2007, to Thomas J. Kryzak, and depicted in FIG. 3A of US Patent 7264713, which is herein incorporated by reference.
- the vessel 10 may be "lowered” into position by operably coupling the vessel 10 to a lifting bag, in tandem with a mechanical lifting device and a rigging unit. Lifting may be advantageously augmented by a buoy/float device with or without a 360° multi-directional propulsion unit.
- a weight of the vessel 10 may drive the edge 80 of the vessel 10 deeper into the bottom 35 of the body of water 40, resulting in creating a releasable seal 85 at the edge 80 of the vessel 10, that may be formed from the sediment layer of the bottom 35 outside of the vessel 10 pressing against the edge 80 and the bottom 35 of the body of water 40.
- the releasable seal 85 thereby may isolate the interior 25 from the body of water 40, and/or the bottom 35 of the body of water 40, that may be outside the vessel 10.
