  • Patent number: 9095795
    Abstract: An anti-drainback valve contains a locking mechanism for securing the valve into to a filter assembly. The locking mechanism is made up of at least two keys that extend from the valve into beyond a cap of the filter assembly in order to secure the valve within the filter assembly. When multiple keys are employed, such keys may be equally spaced around the circumference of the cap. Manufacturing costs are kept minimal as minimal material is required and a two part mold may be employed during manufacturing.

  • Publication number: 20150143784
    Abstract: A form of crossflow filtration particle separator which receives a particle laden moving fluid surrounded by a clear moving fluid at a proximal end, and separates the particles into a collection zone, or collector, in response to vortices created by diagonal slits and baffles located from the center of the particle separator to its distal end. The filter operates horizontally in a small amount of space without use of physical filter media or the need of a high pressure flow, while allowing delicate particles to be separated without damage. Particle collection structures allow the separated particles to be carried away in a separate flow.

  • Patent number: 9023214
    Abstract: The invention provides a method and apparatus for creating plasma particles and applying the plasma particles to a liquid. Liquid feedstock (e.g., water and/or hydrocarbons mixed with biomass) is pumped through a pipeline; the single-phase stream is then transformed into a biphasic liquid-and-gas stream inside a chamber. The transformation is achieved by transitioning the stream from a high pressure zone to a lower-pressure zone. The pressure drop may occur when the stream further passes through a device for atomizing liquid. Inside the chamber, an electric field is generated with an intensity level that exceeds the threshold of breakdown voltage of the biphasic medium leading to a generation of a plasma state. Furthermore, the invention provides an energy-efficient highly adaptable and versatile method and apparatus for sanitizing water using plasma particles to inactivate biological agents contaminating water.

  • Patent number: 8968571
    Abstract: A gas flotation separator for use in horizontal tanks, such as those used for oil storage on board Floating Production Storage and Off-loading (FPSO) vessels, includes dividing the tank into a plurality of chambers operating in series. Prior to entering each chamber, the contaminated aqueous phase is mixed with a stream containing gas bubbles to aid in flocculation and flotation of the immiscible phase contaminant. The gas bubble recycle stream can be generated by injecting a controlled rate of a pressurized gas into a liquid stream of the clean produced water in a process external to the tank or by induction of a gas phase internal to the tank. The mixture flows into the first chamber and impinges on an angled inlet water weir. A portion of the immiscible phase and the gas phase rises to the top of the chamber while the remaining immiscible contaminants flow downward with the aqueous phase to the bottom of the chamber.

  • Patent number: 8557116
    Abstract: The present invention discloses a method and apparatus for separating particles and dissolved matter from a fluid stream. Specifically, the present invention includes a first pressure source which transports untreated fluid into a separator annulus with a filter element disposed therein. The untreated fluid is placed under appropriate pressure sufficient to produce turbulent flow, increased particle kinetics and/or cavitation physics allowing the desired fluid to penetrate and pass into and through the filter media. The filtered fluid is then transported to a collection tank. The contaminant particulate matter retained by the filter media may be removed by the instantaneous reverse pressurization of the separator annulus by a second pressure source thereby removing the contaminant particles away from contact with the filter media, and which may then be transported to a waste collection tank or a concentrator for further treatment.

  • Patent number: 8524080
    Abstract: An apparatus for removing cyanotoxins and excess ions from contaminated water. Contaminated water passes from a storage tank (200), through a sand filter (210), through a reaction chamber (230), and finally through a carbon filter (270). The sand filter removes particulates and some bacteria. Treatment of the water in the reaction chamber first destroys cyanotoxins, algae, and bacteria through the use of high voltage shocks applied between two groups of electrodes (285, 285?), then the voltage on the electrodes is lowered and electrolysis is used to sequester free ions in the water in the region near the electrodes. Partially treated water is removed from the upper portion of the reaction chamber and passed through a carbon filter (270) to remove radiation, and to improve taste and smell. After passage through the carbon filter, the water is potable. The water remaining in the reaction chamber is discarded into a reservoir (265).

  • Patent number: 8038879
    Abstract: A fluid strainer device is disclosed. The device includes a housing which defines an open chamber, the chamber having both at least one fluid input port and at least one fluid outlet port. A plurality of spaced strainer baskets are disposed within the chamber. Each basket has a pair of spaced perforated side panels, a perforated rear panel, a perforated top panel and an open front portion in fluid communication with the chamber fluid input port. Finally, each strainer basket is aligned within the chamber for fluid flow from the chamber input port into the basket's open front portion and out through the perforations thereof to filter debris from the fluid while preventing substantial fluid pressure drop between the input and outlet ports substantially independent of debris buildup within the basket.

  • Patent number: 7875192
    Abstract: A slurry dividing apparatus is configured to divide a main slurry stream into smaller constituent slurry streams, wherein each stream contains a desired proportion of suspended solids. The dividing apparatus includes a main flow channel and a plurality of branch flow channels extending upward from a flow divider that terminates an upper end of the main flow channel. The main slurry stream enters the main flow channel, at an inlet opening thereof, and is decelerated, by an upward extension and expanding cross-section of the main flow channel, before reaching the flow divider and being divided into the smaller constituent slurry streams flowing within the plurality of branch flow channels. Each of the smaller streams flows up and then over a weir, which extends across an upper portion of each of the branch flow channels, and then down into a corresponding discharge flow channel of the apparatus.

  • Patent number: 7803599
    Abstract: A microfluidic fluid flow system (100) is disclosed having a fluid chamber or channel (150) with inlet and outlet ports (104, 106), allowing the fluid channel to be filled with a fluid. One or more flow obstructions or perturbances, such as cylinders (152), are provided in the channel. An oscillatory boundary condition is applied, for example, with a piezoelectric driver (130), that is selected to induce a conservative, low-intensity steady streaming flow in the channel. The low-intensity streaming flow produces distinct eddies that can be utilized, for example, for fluid-dynamically trapping or retaining particles (90) such as cells (92) at well defined locations in the channel. The system may be used to trap and study individual cells or for concentrating or filtering particles in a fluid.

  • Patent number: 7771580
    Abstract: Method and Systems for extracting a concentrated sample of particles include priming a concentrate reservoir by passing a fluid through the concentrate reservoir to remove air. The concentrate reservoir has a first end with an opening and second end with an opening. The second end of the concentrate reservoir is closed off, and particles are accumulated within the concentrate reservoir by use of a particle concentrator. Thereafter, the first end of the concentrate reservoir is closed off, isolating the concentrate reservoir from particle concentrator, from which the particles were obtained. The second end of the concentrate reservoir is thereafter opened, and the particles of the concentrated sample in the concentrate reservoir are extracted to a sample capture reservoir through the second end opening of the concentrate reservoir.
