  • Patent number: 10526938
    Abstract: The arrangement for controlling the flow of laden gases is arranged upstream of an oil separation system and is provided with a check valve, a bypass valve and a stationary segment. The check valve is at least partially movable so as to define a first passage for a forward first flow direction in the event of positive pressure, while the bypass valve is moved rearward by negative pressure so as to clear a second passage for a second, opposite, flow direction. The stationary segment forms a seating surface for the bypass valve. The bypass valve, urged against the seating surface by an elastic biasing member, forms a seat for the check valve. In the event of sufficient negative pressure, the two valves are moved rearward together despite the biasing member and work together to redirect and guide the flow along an escape path corresponding to the second passage.

  • Patent number: 9512014
    Abstract: A vessel for treating an oil-in-water inlet stream houses an inlet flow distributor arranged to direct an inlet flow toward a perforated baffle of a coalescing section, the coalescing section housing a packing and being arranged upstream of a second baffle; a flotation section arranged to receive a flow exiting the coalescing section and being divided by one or more perforated baffles; and an outlet water collecting pipe arranged to receive a flow exiting the flotation section, the outlet water collecting pipe having one or more openings located along its length. The coalescing section may be divided into two sections, with one section preferably housing a different pre-selected sized packing than the other section. The flotation section may include one or more gas-inducing devices. A solid baffle may be arranged downstream of the second baffle and ahead of the flotation section to provide single or dual flow through that section.

  • Patent number: 9486726
    Abstract: The present application discloses a method and apparatus for settling particles from waters that come out of plants that produce waste waters with hazardous components, utilizing vacuum power generated by vacuum generator down the waist water draining line. The method comprising a device with separation and sedimentation chamber, that allows phase separation through a unique cyclone-generating design, which leads to a filtering-chamber equipped with a dual pore-size filter that allows significant segregation of particles by particle size and mass, and thus allows highly efficient separation of hazardous particles from the waste water, which could exit the apparatus of present invention with significantly low content of hazardous particles.

  • Patent number: 9457298
    Abstract: Electricity free operating water purification installation with a membrane filter and a system of automatic backwashing of that filter characterized in that during the operation a fixed percentage is diversed from the outflow of filtered water and is stored in a container under progressive pressure, which to a certain maximum pressure is cut of from a feedback to the membrane filter, so that consequently after filtration of a certain volume of polluted water through the membrane filter the pressure in the container will exceed the maximum resistible pressure by the one way closure, which then will open so that the contents of the container will be forced back through the membrane filter under higher pressure than the original filtration pressure, whereby is provided in automatic closure after the container is emptied.

  • Patent number: 9266045
    Abstract: In accordance with the present invention, there is provided a strainer system comprising a plurality of strainer modules, each of which comprises multiple cassettes or cartridges assembled together in a prescribed arrangement. In the strainer system constructed in accordance with the present invention, the “clean” sides of the strainer modules are fluidly connected to each other by a plenum duct which also has a suction pump fluidly coupled thereto. Integrated into the plenum duct is a pressure released membrane (PRM) which is positioned so as to effectively isolate one of the strainer modules from the remaining active strainer modules included in the strainer system. The pressure released membrane is uniquely configured so as to facilitate the activation of the isolated strainer module when pressure across the plenum duct increases beyond a prescribed threshold.
