  • Patent number: 9394660
    Abstract: A marine barrier has buoyant panels elastically connected with an included angle therebetween, to form a pleated row of panels with hinges arranged in first and second rows. An impact net having cables is attached to a net connection portion of each hinge in the first row. The net connection portions are attachable to the cables with a tension such that, when the barrier is floating and a moving vessel impacts the net, an impact force causes the cables to move relative to the net connection portions, transferring a portion of the force of the impact to the net connection portions, until cable stops on the cable ends engage net connection portions adjacent the cable stops. The force of the impact is then transferred to the panels, which engage the water to transfer the force of the impact to the water, to arrest the motion of the vessel.

  • Patent number: 8388849
    Abstract: An adjustable and removable skimming assembly is provided for attaching to the bow of a watercraft. When mounted, the skimming assembly presents vertically orientated starboard, port and bow cages that house oil absorbent padding. The cages with the positioned pads are largely porous so that at slow watercraft velocities, the water flows through the pads but the oil is retained within the pads across a substantially horizontal plane. As the pads become oil saturated along this common plane, the vertical cages are adjusted to expose a section of the pad that is not saturated. This process is repeated until the entire pad surface is saturated. The resistance force created by the water against the starboard and port cages during movement is countered by a plurality of tethering cables extending from the structural members attached to the bow of the watercraft to the outer edges of the cages.

A preferred material is composed of a combination of SBS and EPDM, formed by an extrusion technique, to create highly fissured generally cylindrical bodies. The sacks may be deployed in areas where oil is floating on water, such as where oil has spilled from tankers on oceans, seas, lakes, or rivers. When the bodies are afloat, oily water can pass through the axial holes of and around the bodies, maximizing the surface area contacted by the oil and minimizing gel blocking. After a time sufficient for the bodies in the sacks to adsorb oil, the sacks can be collected. Various deployment and collection methods are disclosed.

  • Patent number: 7166221
    Abstract: This invention is a system and method for bioremediation of hydrocarbon and organic pollution in fresh and salt water. Hydrocarbon and organic pollution digesting microbes are placed in a floating carrier where the microorganisms are exposed to the pollution and the pollution is digested. The floating element may be a block of polymeric foam. The microbes may be supported on powder such as clay minerals, and the powder may be formed into pellets held in slits in the foam.

  • Patent number: 6923888
    Abstract: The invention relates to a process for treating bleaching liquors from pulping processes based on organic acids. The process is characterized in that inorganic acid, such as nitric acid, phosphoric acid and/or sulphuric acid, is added into a bleaching liquor obtained from the bleaching or a stage closely associated with bleaching, whereby organic acids contained in the bleaching liquor are released into the bleaching liquor. The organic acids are then separated from the bleaching liquor and recycled to the cooking stage to be used as cooking chemicals. The nitrogen-, phosphor- and/or sulphur-containing product thereby produced, from which organic acids have been separated, is recovered to be used as a fertilizer or as raw material for a fertilizer.

  • Patent number: 6869525
    Abstract: A storm drain filter system apparatus includes a skimmer tray having a sediment collection closed bottom and having an inlet side and an outlet side and a hydrocarbon absorbing boom. A plurality of boom support brackets each has a boom holding portion for holding the boom therein and a spacing arm extending from the boom holding portion and attached to one side of the skimmer tray to space the boom in the boom holding portion between the inlet side and the outlet side of the skimmer tray. The skimmer tray extends all or partly around the storm drain opening forming an open center area to allow overflow liquid to flow over the outlet side through the middle area. Sediment is collected in the bottom of the skimmer tray and the boom is supported spaced between the inlet and outlet side of the skimmer tray to capture hydrocarbons and liquid entering the skimmer tray. The liquid enters the skimmer tray on one side of the boom and out the other side of the boom.

  • Patent number: 6852234
    Abstract: A method for in-situ burning of oil slicks on water, including the steps of: 1) providing a plurality of individual floating wicks; 2) positioning the wicks in the oil slick; and 3) igniting the wicks. Additionally, a method for manufacturing floating wicks for use in burning oil spills, including the steps of: 1) providing a wick material having a dry density less than water; 2) applying to the wick material an oleophilic, hydrophobic coating such that the coated wick material has an oil uptake capacity of at least 2 g/g and a water uptake capacity of no greater than 5 g/g; and 3) drying the wick material.

  • Publication number: 20040222160
    Abstract: The invention relates to a method for the removal of contaminant layers from water surfaces by means of planar bodies, made from open-celled foam plastic, whereby the planar body is laid on the surface of the water and, after saturation thereof with the oil, is drawn in. In order to guarantee that, during such a process all planar bodies made from open-celled foam plastic directly reach the site of application, in other words the contaminated water surface, said planar body is paid out under water.

  • Patent number: 6797162
    Abstract: The present invention is a filter system for a curb inlet catch basin which catch basin includes a ramp in the curb front which feeds into a catch basin to allow storm water to run directly along the curb and down the ramp and which also has a grated cover so the water can enter directly through the grate. The water collecting trough is mounted inside the curb inlet catch basin at the bottom of the entrance ramp and has raised walls for collecting runoff water. A weir is formed into one of the raised walls allowing the water to run out of the trough. An elongated hydrocarbon collecting boom is removably attached adjacent the weir and positioned for the drain water passing through the weir to pass thereover. The catch basin is removably mounted to the trough adjacent the weir and positioned to receive water runoff from the trough through the weir and over the hydrocarbon collecting boom.

  • Patent number: 6767456
    Abstract: An insert for use in a sewer system to remove oils and solvents carried by surface water runoff. The insert includes a holder and a quantity of water permeable, hydrophobic, oil and solvent absorbing material such as melt blown polypropylene. The holder has two functions. It holds an effective quantity of the absorber and holds it in such a way that the surface water is exposed to the absorber to allow oils and solvents to be absorbed. The insert in preferably placed, cartridge-like, at the inlet or outlet of the sewer system so that it may be quickly checked, replaced and serviced. In one embodiment, the insert also contains a leaf trap.

  • Publication number: 20040134858
    Abstract: A fluid pollution prevention system for preventing the discharge of hazardous waste from a bilge of a marine vessel, and removal of the same from the bilge. The system includes an absorber for absorbing hazardous waste from a fluid in the bilge. The system further includes a locator for locating the absorber in a predetermined orientation relative to a bilge pump to prevent the discharge of hazardous waste from the bilge. In one embodiment of the invention, the locator is an upstanding member in relation to the fluid in the bilge and includes at least one locator channel defined along at least a portion of the locator for slidable receipt of the absorber. According to this characterization, the absorber is movable along the locator channel as a function of the bilge fluid level to absorb hazardous waste from the fluid and isolate an inlet of the bilge pump from receipt of the same.
