A skimming and separation device comprising an outer casing (1) provided with constructions to directly or indirectly fasten all parts, defining a compartment (2), and a floater (3) configured to create the skimming function of the device, the floater is attached at its lower side to an essentially vertically arranged bellow (4) allowing the floater to adapt flow into a substantially circus volume and allowing the floater to move from an upper position with essentially no flow into the compartment (2) to a lower position allowing flow of water and debris follow the contours of the floater (3) in a downward direction into the device. A power device (8) is provided and includes a propeller to achieve in-flow and outflow of the device. The device further comprises a central tube (c) arranged along a vertical center axis of the compartment and configured to receive said flow of water and debris, and at least one central rotation member being structured to generate a downward directed and central rotating flow of said water and debris within said central tube (c).

A floating-oil recovery device includes: a bubble-curtain generation mechanism configured to discharge air into water to generate a bubble curtain in the water so as to increase a thickness of a film of floating oil while regulating spread of the floating oil; and an ejector configured to recover an oil-water mixed fluid having the floating oil and the water mixed with each other by jetting high-velocity water toward the film of floating oil enclosed with the bubble curtain to destroy the film of floating oil.

A vessel that is configured to remove trash from a body of water includes a trash intake portion, a trash processing portion, a compactor, and a plurality of components configured to allocate compacted trash onboard the vessel.

The invention relates to a water intake floating row cleaning system, including first vertical guide rail assemblies, a floating row, submersible pumps, water spraying assemblies, second vertical guide rail assemblies, floating fences and pumping assemblies, wherein the water spraying assemblies are communicated with the submersible pumps, and the submersible pumps pump the water of the river channel and spray the water towards the outside through the water spraying assemblies; and the floating fences stretch across the water intakes and float along with a water level, and the pumping assemblies are used for pumping out garbage blocked by the floating fences. The invention has the effect of efficiently cleaning the floating garbage at the water intakes.

A system for forming an underwater air curtain, that turns the ocean above it into a gas is anchored on the ocean floor, so the curtain's bubbles travel from the ocean floor to the surface. The system is formed by arrays of air distribution tubes carrying air dispersal heads that are powered by an air supply and air batteries. In the shallows, of 30 ft. or less, ocean waves are deleted, oil is repelled, marine animals have a barrier that they cannot enter when the system is activated. Used at deeper depths, the system has the ability to change ocean temperatures, by using bubbles to bring cold water from the ocean floor to the surface thus protecting coral. The system also works as a sound barrier, because the ocean is no longer solid above it.

A method for collecting a surface layer of a liquid into confined area, method including forming confined area by means of wall structure and moving some of surface layer of liquid into confined area by means of a flow of air directed into confined area through an opening made into wall structure of confined area so that amount of substance in surface layer of the liquid increases in confined area in comparison with surroundings. The bottom edge of opening made into wall structure of confined area is arranged to be below surface level of liquid outside confined area whereas its top edge is substantially above surface level of liquid outside confined area. The surface level of liquid inside confined area is arranged to be kept substantially on same level with surface level of liquid outside by providing a continuous liquid flow connection through lower portion of confined area into surroundings.

Harvester systems and methods for use in liquid environments are disclosed herein. In an embodiment, a harvester includes a cutter assembly and a frame. The cutter assembly is configured to remove solid material from a liquid environment and includes a cutter housing, one or more cutting blades for cutting the solid material, and a hose connector configured for connection to a hose for pumping the solid material out of the cutter housing. The frame is configured to attach the cutter assembly to a plurality of different vehicles configured to operate in the liquid environment and includes a first adjustment assembly adjustable for removable attachment to the plurality of different vehicles and a second adjustment assembly adjustable to raise the cutter assembly above a surface of the liquid environment and to lower the cutter assembly at least partially into the liquid environment.
