    Abstract: An improved pool skimmer basket assembly with skimmer vent tower adapter for mounting a skimmer vent tower on a pool skimmer basket allows for the existing design of a skimmer vent tower to be retrofitted with any pool skimmer basket and/or any pool skimmer. The adapter is reversibly secured between any pool skimmer basket available on the market and the skimmer vent tower without requiring modifications to either part. Applicant's assembly utilizes the substantially centrally positioned skimmer vent tower of an existing design to provide a means by which water is vented through the basket, even when the strainer orifices are clogged. When the user requires a different size of basket and/or a new basket, he can easily remove the adapter attached to the inner bottom portion of the basket and place it on another basket without forgoing the use of the skimmer vent tower altogether.

  • Patent number: 8449776
    Abstract: Our idea is a new procedure that can be used to clean up and recover oil from spills or oil leaking from damaged ships or rigs. The reclamation is accomplished by restoring the oil's light density. This is accomplished with density control by adding light cycle oil, (LCO), with a density of 0.82 g/ml, to the oil being recovered for the purpose of reprocessing in refineries. Recovery is made possible through the application of solubility rules found in organic chemistry. LCO is a mixture of many different molecular weight hydrocarbons that have many different numbers of carbons in their chains, branches, or rings. Each of these hydrocarbons dissolves a small part of the oil preparing the mixture for collection and reprocessing as refinery feedstock. Furthermore, this idea can prevent the need for landfill storage and offset the cost of recovery.

In some versions, the water may be 12 to 14 feet above the lowest point on the floor. A portion of the floor may slope toward a vacuum head that is indirectly coupled with a source of suction. In some versions, at least the vault floor is lined with a liner that has a low coefficient of friction and is corrosive resistant. The source of suction may be a vacuum hose of a vacuum truck.

  • Patent number: 8366943
    Abstract: The invention relates to an apparatus and method for collecting material from a water system, especially from the surface or close to the surface of a water system. The method comprises: maneuvering an apparatus with a cargo space in a water system; conducting water, present in the surface and close to the surface of the water system, and material therein to be collected, in response to the vessel's advancing speed through a collect opening, located in a fore section of the apparatus in its traveling direction, into the cargo space; conducting water from the cargo space back into the water system through an exhaust opening in the cargo space's bottom.

  • Patent number: 8343355
    Abstract: A dissolved air flotation system and method for purifying fresh water. The system is self-contained within a standard shipping container, with all components disposed in-line within the shipping container. Float is removed from the flotation tank with a skimmer that drives float downstream onto a conveyor belt, and the conveyor belt conveys float away from the flotation tank, in the downstream direction, and deposits the float in a collection tank. Clean water may be drawn from the flotation tank continuously, while float may be removed periodically.

  • 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.

  • Publication number: 20120248045
    Abstract: A new automatic pool skimmer cleaning system includes an auto clean skimmer, debris basin, and pump. A check valve line runs from the side of the skimmer to the debris basin. When the pump is run, suction on the check valve line opens the valve and allows water and accumulated debris in the skimmer to flow into the debris basin, where debris is caught in a debris basket. The filtered water is returned to the skimmer. Debris accumulates in the debris basin over a season and is occasionally emptied. The system's pump operates independently of the pool's filtration system and is run when the filtration pump is cycled off. For vacuuming, a vacuum attachment connects to the check valve line and allows vacuumed water to be passed directly through the debris basin and debris basket and then returned to the filtration system, avoiding the need to backwash the filter.

  • Patent number: 8273250
    Abstract: Skimmers, barges and related methods recover heavy oil or bitumen from contaminated water environments such as tailings ponds. The skimmer has an articulated mesh-like conveyor driven around a drum by a drive sprocket. A pusher mechanism discharges bitumen or heavy oil from cavities in the conveyor. In one embodiment, the skimmer includes an automatic depth control system. In other embodiments, knife-edged shear plates remove heavy oil or bitumen adhering to the conveyor and drum. A barge may incorporate multiple parallel skimmers. The barge may include a bitumen-transfer pump having an annular fluid-injection flange that generates an annulus of lubricating fluid inside a discharge hose. A method of skimming heavy oil or bitumen involves using a skimmer that automatically adjusts its elevation or depth based on a control signal generated by a depth sensor. Another method recovers and transfers bitumen by lubricating the discharge hose using the annular fluid-injection flange.

  • Patent number: 8268167
    Abstract: Separating apparatus, for separating a substance from a liquid on which the substance can float, comprises: a separation chamber; an inlet adapted to convey a supply comprising the substance and the liquid into the separation chamber; and an outlet adapted to convey liquid collected in the separation chamber out of the separation chamber. The inlet is arranged such that, in use, the supply emerging from the inlet into the chamber is directed upwardly into the chamber, and the apparatus further comprises venting means arranged to convey gas out of the chamber. The apparatus may further comprise a floating pick up connected to a pump for pumping the supply to the separation chamber. In certain examples a non-floating pick up is used, comprising an elongate hollow body with a pick up inlet mouth in the form of a vertical slot extending along a length of the body.

    Abstract: A separator for separating F.O.G. from an effluent that contains F.O.G. includes a tank, an inlet to the tank for receiving effluent that contains F.O.G., and an outlet to allow grey water to leave the tank. The tank has a size to enable stratification of a layer of F.O.G. present in the tank on water in the tank, and first and second thermocouples are positioned at differing levels in the tank. Conductors couple the thermocouples to sensors, and differing voltages in the thermocouples can be sensed to determine if the thermocouples are surrounded by F.O.G. or water.

  • Patent number: 8210271
    Abstract: One or more aspects of the present invention is directed to a fire suppression system for use with an oil and vapor recovery system, such as for example, a system having a float system for adjusting the height of oil and vapor recovery intakes. The float system is preferably adjustable to allow connection of additional floats to maintain buoyancy and keep the vapor intake above the level of the oil in the holding tank and to maintain the oil intake above the level of the water contained in the holding tank. Vapor is drawn out of the holding tank using a vacuum assisted siphon. Oil can be withdrawn from the holding tank by suction or simply by letting the oil flow into an outlet by gravity. By reversing the flow of the existing suction pipes or by providing additional inlet pipes to the nozzles, fire suppression or other chemicals can be added to the tank without having to gain physical access to the tanks, thereby potentially saving lives, money as well as the fluids within the tanks.
