  • Patent number: 10781113
    Abstract: A system and method of the purification of drinking water, ethanol and alcohol beverages is based on the action of hydrodynamic cavitation processing of microbiological and chemical contaminants, micro particles and colloidal particles. The fluid flow moves at a high rate through a multi-stage cavitation device and filtration module to generate hydrodynamic cavitation features in the fluid flow. The cavitation features generate changes in the velocity, pressure, temperature, chemical composition and physical properties of the liquid. The cavitation features also prevent the deposition of contaminants upon and remove contaminants from the surface of the filter module, reduce the load on the filter elements and increase the life of the filter module.

  • Patent number: 10519617
    Abstract: In certain embodiments, a sand-boil filter includes a hollow, conical, water-porous structure made of a mesh material having spaced mesh holes. The filter is inserted narrow-end down into a sand boil to allow water to flow from the ground through the mesh material and out the top of the sand boil, while blocking solid matter larger than the mesh holes from passing through the mesh material. In some implementations, the filter is filled with gravel that holds the filter in place while allowing water to flow out of the sand boil. Such filters prevent sand boils from growing while relieving the underground hydrostatic pressure that created the sand boil in the first place and inhibiting subterranean erosion that can cause failure of a nearby levee. The conical shape provides relatively large surface area that inhibits clogging and allows each filter to be used for a range of different sand-boil sizes.

  • Patent number: 8727134
    Abstract: A sealing device (24) of a filter system (10) for filtering fluids, in particular of a motor vehicle, with a sealing ring (26) is described. The sealing ring (26) serves to seal a pipe (16), in particular a central pipe of a filter housing (12), that penetrates through a flange-sided opening (18) of an end plate (20), in particular of an end element of a filter element (14). The sealing ring (26) features a central section (58) that connects it with the end plate (20). The sealing ring (26) features in its axial direction on both sides of the central section (58) elastic sealing sections (60, 62) which cause each a reduction of the inner diameter of the sealing ring (26) compared with the central section (58).

  • Patent number: 8518002
    Abstract: A removable manifold for a medical/surgical waste collection system. The manifold is dimensioned to be mounted to a receiver integral with the system. The manifold includes a includes at least one fitting through which waste is drawn into the manifold. The fitting opens through an inlet port into a void space internal to the manifold. A backflow prevention valve is disposed in the manifold void space. The backflow prevention valve includes a static hub to which a driver for engaging a complementary valve internal to the receiver. The valve regulates flow between the receiver and the down line components of the waste collection system. The valve is normally closed. When the manifold is fitted to the receiver the driver engages the valve so as move the valve to the open position. This allows fluid flow from the manifold and receiver to the downstream components of the system.
