Two segments according to the invention, which form a brush structure created by brush fibres and plastic rings, are joined together by bolts or screws and sleeves with a water-permeable discoid hub, in such a way that a separate brush structure can be joined to the segments by stud bolts or similar, to the metal ring of which a plastic ring, equipped with brush fibres, is attached for the collection of very heavy oils. For the cleaning of the brush fibres of the segment and the good recovery of the oil being collected, there is a curved metal sheet, preferably on supports, as a continuation of the cleaner, and which forms a casing-like space, preventing the oil flowing off the brushes from returning to the water circulation and improving the collection capacity. The device is suitable, for instance, for the collection of all grades of oil, with continuously changing properties.

A lightweight, bioplastic, mobile, floating oil spill mechanical/biological recovery system is dimensionally compact, and quick to assemble. The floating platform can be readily positioned within any waterborne oil/contaminant spill area. After assembly, this platform or apparatus can be directed by either a hand-held digital radio control transmitter or GPS directed mechanism. A lower, multi-roller slip-on belt is designed to be mounted over a circular base support aeration hub assembly with alternating/spaced slotted ring water drainage separators. The belt and aeration assemblies dip bioaugmentation product into the contaminant site thereby exposing microorganisms to both oxygen and target contaminant for treatment and metabolism. Various mechanisms for enhancing metabolic activity of the bioaugmentation product operate in tandem with the primary belt and aeration assemblies to promote effective contaminant metabolism and overall treatment regimes.

An oil skimming device for the removal of oil located at the surface of a body of water includes a float, at least one skimming surface, a sorbent material, at least one scraper, and a motor. The float is arranged such that the device rests on the surface of the body of water from which the oil is to be removed. The at least one skimming surface is rotatable about an axis such that when the device is floating in the water a portion of the ridged skimming surface is above and a portion of the skimming surface is below the water surface. The sorbent material is removably attached to and substantially covers the skimming surface. The sorbent material is configured to rotate with the skimming surface and to sorb oil as the skimming surface is rotated.

Provided is a device for collecting oil contained in ice. The device includes a lifting device fixed for example to a vessel, a cage of separation adapted to be lowered into the water between the ice blocks by means of the lifting device and formed by a box which lets water and oil but substantially no ice, and an oil collector for collecting the oil on the water surface in the space defined by the separation of cage.

The present invention relates to an algae collection device and, in particular, to an algae collection device using an escalator-type lift equipped with a screen having a level state. The present invention may collect algae using an escalator-type lift equipped with a screen having a level state while the algae do not move down. The present invention may effectively collect, into a collection box, the algae transported on the escalator-type lift by means of compressed air generated by a compressor.

The invention relates to an oil collector including a brush (3), provided with substantially straight bristles (1) and a horizontal shaft (2), and a cleaning structure in the upper part of the brush for cleaning the brush from oil. According to the invention, the bristles (1) of the brush (3) are substantially parallel to the horizontal shaft (2).

The apparatus is for use with an oil slick. The apparatus includes a rolling vehicle having a vehicle frame; a lift system supported by the vehicle frame; a hydraulic-control system supported by the vehicle frame; an oil-holding tank system supported by the vehicle frame, and an oil-slick skimmer system configured to be lifted and moved by the lift system onto the oil slick.

A portable oil skimmer includes a collection unit configured to collect spilled oil while floating on the surface of the ocean. The collection unit includes a main body configured to allow a first oil-skimming member to be rotatably mounted on the front end thereof, a second oil-skimming member to be rotatably mounted on the rear end thereof, and a pipe to be connected to the upper portion thereof so as to communicate with the interior thereof, a pair of buoyant bodies mounted on two side surfaces of the main body, with the main body interposed therebetween, and an oil pump disposed in the main body and configured to convey oil collected by the first oil-skimming member and the second oil-skimming member to the outside of the main body through the pipe.
