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.
