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 group of inventions relates to the field of organic chemistry and can be used for cleaning water, industrial and domestic waste water or waste water sediment, and for the containment and recovery of petroleum and petroleum product spills in large bodies of water, rivers, lakes and seas. In the claimed group of inventions, aqueous solutions of polysaccharide microgels, having a molecular mass of 20000-200000 daltons and a particle size of 50-600 nm, are used as a substance for cleaning water of petroleum and petroleum products. Moreover, low concentrations of polysaccharide microgels in water, ranging from 0.1 to 20 g/l, are used. Said solutions are used as a surface modifier for a filter used in separating water-oil emulsions, as a sorbent for the containment and recovery of oil spills in an aqueous medium, and also as a coagulant for the cleaning of water polluted by petroleum and petroleum products. The technical result is in making it possible to recover a commercial product, recovered during the process of cleaning water of petroleum or petroleum products, and to recover the starting substance for the reuse thereof, while simultaneously simplifying the slurry utilization process.

A hybrid water filtering cleaning and quality monitoring device integrates multiple elements into one main system, including oil filtering, bacterial management, trash collection and water quality monitoring.

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.

Method and system is described to enhance operations for managing the hydrocarbon release. The system utilizes an airborne detection device equipped with measurement components and communication components. The system may utilize various measurement techniques to determine the thickness of the oil slick. This remote detection method may provide a dedicated airborne detection device for each response vessel and that can identify the location and thickness of the oil slick.

An apparatus for harvesting algae from an open body of water includes a boat having a pair of spaced apart parallel flotation members and a deck disposed on and connected to the members. The spaced apart members define an area therebetween forming a process channel. A separating mechanism disposed on the boat separates the process channel into a plurality of process channel sections arranged in series. The process channel sections are disposed intermediate the flotation members. Each of the process channel sections include a deflector plate, a scum beach, a scum trough, and diffused air piping. The diffused air piping is in fluid communication with a dissolved air flotation system.
