An apparatus, system and method for removing and treating contaminated materials on a bottom of a body of water and introducing growth packets to revitalize the treated bottom of the body of water. The structure may comprise a vessel with an open face. The vessel may be lowered down to the bottom of the body of water with the face facing down. As a result, the vessel and the bottom form an isolated space. The structure may comprise at least one agitating device(s) for stirring up the materials inside the vessel so as to form a mixture containing the sediment materials which in turn contain the contaminants. Multiple at least one pipe(s) may be coupled to the vessel for transporting the mixture out of the vessel for processing (filtering, treating with chemicals, etc.) so as to neutralize or eliminate the contaminants in the mixture. Then, the treated mixture can be returned to the inside of the vessel via the at least one pipe(s).

A marine debris collection device includes an outer container, an inner container provided inside the outer container so as to be movable in an upward-downward direction with respect to the outer container, a pump to move the inner container downward and cause seawater and debris to flow into the inner container via an opening, and a lower buoyant body detachably attached to a lower portion of the inner container to maintain the opening of the inner container above a water surface when the pump is not driven.

Apparatus, systems and methods for collecting debris from a body of water onto a waterborne vessel include at least one inflow regulator (IFR) disposed at least partially in a cargo compartment of the vessel proximate to at least one intake opening at the front end of the vessel. Each IFR is configured so that the front end thereof floats at or near the surface of liquid contained in the cargo compartment to limit the inflow into the cargo compartment to debris/water which flows over the IFR and is disposed at or near the surface of the body of water.

The cleaner according to the invention includes a body part, which includes curved wiping tongues. The lower part of the body is the cleaner's curved lower plate and in its upper part are upper plates and an attachment plate, which is attached to the body of the collector by an attachment beam. The construction of the collector is based on discs surrounding a drum and permitting water to flow through them, to which are attached plastic rings and, attached to them, a brush ring formed of brushes extending over the curved rear wall. The invention also discloses a cleaner, by means of which the brushes are cleaned, which, for example, are attached to a V-shaped brush structure, in which there is a plastic bodied brush ring, and in the cleaner there is a point-shaped plate and its bent point shape.

A floatable-material harvester is disclosed, including vacuum source, transport hose, and a floatable-material receiver. In one embodiment, the transport hose has at least one air inductor/intake along its length, which allows air to enter the transport hose to accelerate its contents, by negative pressure air induction. In another embodiment, a transport hose has at least one floatable-material thruster along its length, comprised of at least one nozzle, which provides pressurized fluid (e.g., air or water) in the direction of the flow of the harvested floatable material by positive pressure induction. A method is disclosed whereby the floatable material harvester is used to harvest an absorbent material (e.g., wood chips, straw, perlite, zeolite, polypropylene mesh, titanate nanofibres) that has absorbed a pollutant (e.g., oil, solvent, radioactive isotopes) from a beach or in water.
