  • Patent number: 10683655
    Abstract: An expansion ring mountable in a storm drain for supporting a filtering apparatus includes a ring-shaped expansion member having an adjustable diameter which is cut transversely to define two open end portions thereon which face each other and which are separated from each other by a predetermined distance to define a gap therebetween. A wedge assembly is positioned at the gap between the open end portions of the expansion member and is adjustable to increase the diameter of the expansion member. When the wedge assembly is adjusted to increase the diameter of the expansion member, the expansion member tightly engages a side wall of a portion of the storm drain in which the expansion ring is mounted to secure the expansion ring, and a filtering apparatus supported thereby, in a desired position.

  • Patent number: 10675562
    Abstract: A nozzle is provided for a header conduit. The nozzle includes an inlet that is resistant to clogs caused by flat materials covering the inlet. The inlet generally includes multiple pathways to an elongated passageway through which waste liquid and sludge (“waste”) are guided and enter the header conduit. In one embodiment, the elongated passageway is oriented to guide the waste along a path that is tangential to at least the inner surface of the header conduit which such incoming waste first contacts. When the conduit has an inner surface of circular cross-section, the passageway may optionally be elongated enough that the incoming waste enters the header conduit along a path tangential to the circular surface. To better assure axial flow of the waste in the conduit to an outlet, in one embodiment the passageway provides both the tangential flow and is at an acute angle to the longitudinal axis of the conduit. The incoming waste is thereby provided with an axial component.

  • Patent number: 10640965
    Abstract: The present invention relates to a manhole capable of an oil-water separation. An external air is introduced into a manhole through a inlet guide pipe and naturally and easily separate an oil-water mixture sewage into an oil sewage and the water sewage. The manhole may be installed in an area where the amount of the oil sewage and the water sewage is irregular, e.g., in an area single-family houses, multi-family houses, restaurants, roads, parking lots, gas stations are clustered. According to the present invention, an inlet guide pipe is provided in a manhole body and coupled to an inlet pipe. An oil-water mixture sewage flows in the manhole through the inlet guide pipe. The oil-water mixture sewage drops from the inlet guide pipe, causing turbulence or swirl. Due to the turbulence or swirl, the external air is also introduced through the inlet guide pipe and separates the oil-water mixture sewage into an oil sewage and a water sewage by a specific gravity difference.

  • Patent number: 10633814
    Abstract: Two segments according to the invention, which form a brush structure created by brush fibres and plastic rings, are joined together by bolts or screws and sleeves with a water-permeable discoid hub, in such a way that a separate brush structure can be joined to the segments by stud bolts or similar, to the metal ring of which a plastic ring, equipped with brush fibres, is attached for the collection of very heavy oils. For the cleaning of the brush fibres of the segment and the good recovery of the oil being collected, there is a curved metal sheet, preferably on supports, as a continuation of the cleaner, and which forms a casing-like space, preventing the oil flowing off the brushes from returning to the water circulation and improving the collection capacity. The device is suitable, for instance, for the collection of all grades of oil, with continuously changing properties.
