  • Patent number: 11186980
    Abstract: A method of removing sediment from fluid flow within a storm water drain pit by deflecting flow entering the pit towards the side walls of the pit by one or more deflectors. This reduces the energy of the fluid flow and promotes settling of sediment within the catch pit. Each deflector is preferably of a concave form and may be located in a storm water drain pit bag or suspended. A removable catch basin receptacle for a storm water drain pit includes a container has a low flow outlet defining a fluid path for fluid at a first level within the container to a second level, higher than the first level, outside the container. An overflow path provides a fluid flow path out of the container at a level higher than the first or second level.

  • Patent number: 9334178
    Abstract: A grit removal unit including an influent channel directing wastewater with grit into a round grit removal chamber and an effluent channel receives wastewater output from the chamber. A divider wall extends upwardly between the sides of the influent channel, and gates at the upstream end of the divider wall are adjustable to selectively open channel portions on opposite sides of the divider wall. An output guide member is mounted to allow selective adjustment of output flow opening width “c” to the effluent channel. The output guide member has a horizontal bottom extending from the chamber into the effluent channel across the width of the output opening, and a guide wall extending upwardly from the guide member bottom. The guide wall has a forward end spaced from the chamber annular vertical wall to define the output flow opening width therebetween.

  • Patent number: 9327999
    Abstract: An inclined plate sedimentation device includes a plurality of parallel spaced inclined plates, each at a plate inclination angle relative to a horizontal axis, an influent fluid source that provides a fluid to the device such that the fluid flows between the inclined plates, and at least one vibratory source operatively coupled to at least one of the inclined plates for providing vibration. The inclined plates have tapered lower ends for reducing eddy currents between adjacent inclined plates upon vibration. The vibratory source may be at least one of mechanical, electrical, air-driven, hydraulic-driven, a sonic wave device, and a microwave device.

  • Patent number: 9289701
    Abstract: An open-channel infeed conduit of a feed dilution system of a thickener/clarifier settling tank is provided with orifices between its upstream inlet end and its outlet end. The orifices are positioned proximate to and in fluid communication with the clarified liquid phase in the tank to draw clarified liquid from the tank into the conduit responsive to or by virtue of momentum transfer between the flow of the liquid slurry feed stream in the conduit and the clarified liquid in the tank.

  • Patent number: 9084947
    Abstract: Apparatus and methods for conveying a flow of oil-containing liquid into an oil separation skim tank, and a skim tank incorporating such apparatus and methods, are disclosed. One such apparatus includes at least one diffuser, the diffuser defining an intake opening configured to receive the flow of oil-containing liquid and an exhaust opening configured to convey the flow of oil-containing liquid into the skim tank. The diffuser is configured to cause the flow of oil-containing liquid to have a greater horizontal width at the exhaust opening than at the intake opening, while minimizing vertical divergence of the flow at the exhaust opening.

  • Patent number: 9023216
    Abstract: Apparatus is disclosed for substantially reducing the momentum, velocity, or both of a first liquid that is flowing into a second liquid. The device allows one to substantially reduce or even eliminate large-scale turbulent eddies that could otherwise be produced by liquid flowing into or within a vessel, for example in a clarifier. Suitably-sized and positioned plates and baffles induce changes of flow direction in a limited volume. By the time the fluid leaves this volume, the fluid velocity is low, and turbulence is nearly or entirely eliminated. Several of the devices may be placed at different inputs within a single clarifier, and thus increase efficiency further.

  • Patent number: 8945256
    Abstract: A desanding system has an elongated vessel that is tilted at a non-zero inclination angle. A fluid inlet at the vessel's upper end discharges a gas stream having entrained liquids and particulates and a fluid outlet into a freeboard portion formed adjacent an upper portion of the vessel above a gas/liquid interface formed below the fluid outlet. A belly storage portion is formed below the interface. The freeboard portion of the vessel has a freeboard cross-sectional area that diminishes along the interface from the fluid inlet to a fluid outlet spaced away from and lower than the fluid inlet. The cross-sectional are of the freeboard portion causes precipitation of the entrained liquids and particulates therefrom and collect in the belly portion of the vessel. A desanded gas stream, being free of a substantial portion of the particulates is removed from the vessel through the fluid outlet.

    Abstract: A vessel for use in settling particulate matter from a fluid stream is provided. Fluid is introduced to the vessel through an angled inlet, with flow into the vessel both disrupted and deflected by an inlet baffle, to redirect the fluid stream parallel to a horizontal axis of the vessel. The velocity of the fluid stream is reduced within the vessel, allowing the particulate matter to settle along the bottom of the vessel.

  • Patent number: 8940176
    Abstract: A method of extracting a liquid phase from a suspension, the method comprising: injecting said suspension into a duct presenting a first section that is straight and a second section that is curved; and at the outlet from said curved section of the duct, extracting a liquid-enriched fraction of said suspension that is spatially separated from a particle-enriched fraction of the suspension; the method being characterized in that the injection flow rate of the suspension and the geometry of the duct are selected in such a manner that: in the straight section, lift forces cause particles to be superconcentrated in a ring around the longitudinal axis of the duct; and in the curved section, Dean secondary flows deform said ring and give rise to spatial separation between said liquid-enriched fraction and said particle-enriched fraction. A device for implementing such a method.
