  • Patent number: 10940930
    Abstract: An online antifouling ship ballast water treatment system includes a ballast water main pipeline, a ballast water branch pipeline, a dispensing pipeline, a filter on the ballast water main pipeline, an electrolysis unit on the ballast water branch pipeline, and a dispensing pump on the dispensing pipeline. Some of seawater introduced into the system is filtered by the filter and flows to the ballast water branch pipeline and the electrolysis unit, some of seawater electrolyzed by the electrolysis unit is reinjected to the filter through the dispensing pump and the dispensing pipeline after a ballast process is completed, and kept in the filter until a next ballast operation, so that growth and propagation of marine organisms in the filter can be inhibited by sodium hypochlorite contained in a TRO solution when a ballast pump stops working. The present invention also provides a ship ballast water treatment method.

    Abstract: A stormwater filter cartridge includes a housing with internal filter medium disposed along a flow path between a water inlet and a filtered water outlet. A solid wall float tube in a drainage space has an open lower end and open upper end and is movable between a lowered position and a raised position. As the housing fills, water level in the housing rises to cause the solid wall float tube to move to the raised position and a negative pressure draws fluid through the filter medium. As water level outside the filter cartridge drops, air enters the housing and causes the solid wall float tube to drop to the lowered position, and filtered water in a fluid reservoir backflows through the filter medium while air enters the housing by passing upward through the solid wall float tube so as to enhance rate of backflow.

    Abstract: Disclosed herein are embodiments of a solar-activated photochemical fluid treatment system, some of which comprise an group of modules coupled together with attachment mechanisms, the group of modules comprising one or more floats. The modules comprise a porous substrate and a semiconductor photocatalyst coupled to the substrate. The group of interconnected modules can be configured to float at or near the surface of a body of fluid such that the fluid and sunlight can be in contact with the photocatalyst. The fluid treatment system can, responsive to solar radiation applied to the photocatalyst and to the fluid, induce photochemical modification of contaminants and living organisms in the fluid. Related methods are also disclosed.

  • Publication number: 20130180930
    Abstract: A boat is provided with a pipe assembly operatively connected to a water pump. The pipe assembly can be raised and lowered between transport and use positions. The pump draws water from the body of water, and the water is discharged through a series of holes in a substantially horizontal pipe adjacent the bottom of the body of water. The impingement of the ejecting water dislodges oil or other substances, which then float to the surface for collection.

  • Publication number: 20130168324
    Abstract: A method for retracting oil on a water surface, and a method for reducing the quantity of oil on an oil control boom are described. Spreading of oil can be reversed by reducing the surface tension of the seawater, for example by using a low concentration of a water-soluble surfactant, such as a non-ionic surfactant. A controlled amount of the surfactant may be continuously discharged at the inner-wall of a spill control boom surrounding the oil spill. The spilled oil is caused to retract away from the boom toward the center of the area encircled thereby, such that the oil layer becomes sufficiently thick to be more effectively removed mechanically. The surfactant also reduces the amount of oil on the spill control boom, whereby the boom can easily be removed from a remediated oil spill and reused at a later date without further cleaning.

  • Publication number: 20130153513
    Abstract: The present invention relates in a first aspect to a liquid removal device, and in a second aspect to a method for removing a liquid, such as oil or an algae slurry, from a surface of water. The device comprises a circumferentially extending flexible wall element defining together with a bottom part a suction chamber for receiving the liquid. A floater body is sealingly connected to the flexible wall element at an upper edge of the latter, and is able to effectuate a movement in a direction that is substantially perpendicular to the surface of water. The floater body has a circumferentially extending outer member and an inner member. The inner member is adapted to receive a buoyant force exerted by the liquid contained in the suction chamber. The outer member has an upper circumferential edge for receiving the liquid.

  • Publication number: 20130092633
    Abstract: A modular liquid/liquid gravity separation device for separating the aqueous phase and the oil phase of a crude oil at the sea bottom. The device has a plurality of separation modules coupled to a common manifold device. Each separation module has a fluid delivery pipe coupled to at least one gravity separation pipe by a tubular bend device. The common manifold device has a first tank fed with crude oil by a feed pipe resting on the sea bottom via a first inlet orifice, a plurality of first outlet orifices feeding crude oil to said delivery pipes. The aqueous and oil phases are separated within the separation pipes before being delivered into a second tank via second inlet orifices of the second tank to which the separation pipes are coupled. The oil phase is conveyed to the surface from the second tank via a first removal pipe. The aqueous phase is conveyed to the sea bottom.

  • Publication number: 20130082007
    Abstract: This invention relates generally to products and processes, and more specifically, to systems and method for recovering oil from water. In one embodiment, a towed net system is provided which has the ability to collect free floating oil to one or more end points from which either/both hydrodynamics and/or one or more powered pumps are used to deliver channeled and collected oil to one or more receiving vessels. In some embodiments, two wing nets are provided, either/each towed by one or more vessels, connected to one or more end receptacle nets. From the one or more end receptacles, the channeled and collected oil is delivered to one or more receiving containers also connected to the one or more end receptacles. The system can be scaled based on the horsepower of the two or more towing 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.

  • Patent number: 8343358
    Abstract: A three-hulled oil combatting vessel (500) has a separating structure (100), which pushes ice blocks (J1), which move between the middle hull (SH1) and side hulls (SH2, SH3) from the prow to the stern, underneath the water surface (WL1). The separating structure (100) may be a grate in the longitudinal direction of the vessel (500). The density of the oil (B4) or oil refining product to be collected is smaller than that of the water, so the oil (B3), which has been separated from the ice blocks (J1) that were pushed down, tends to rise through the separating structure (100) to the water surface. The separating structure (100) separates the oil (B3) from the ice blocks (J1) for easier collection into a container. The separated (B4) oil can thus be collected from the relatively ice-free water surface (WL1) with an oil collecting device (200), which may have a brush skimmer.
