  • Patent number: 9815002
    Abstract: A multi-phase separation apparatus shapes fluid flow in a flow shaping line preferably shaped to have a plurality of loops with consecutively decreasing diameters. Shaping the two-phase flow drives the heavier, denser fluids to the outside wall of the flow shaping line and allows the lighter, less dense fluids such as gas to occupy the inner wall of the flow shaping line. With the gas positioned on the inner wall, an exit port on the inner wall permits a majority, if not all, of the gas, along with a minimal amount of liquid, to be diverted to a conventional gas-liquid separator at a flow rate much lower than the total flow rate within the flow shaping line. The remaining liquid flow in the flow shaping line is subsequently introduced into an adjustable phase splitter to separate different liquid components from one another.

The apparatus includes a hollow tube (11) sized and positioned to discharge a fluid stream where the solids within the fluid stream have a specific gravity less than one. The hollow tube (11) includes an inward facing opening that makes an oblique angle along its entire circumference with respect to a longitudinal axis of the hollow tube (11). This arrangement is especially useful in municipal and sanitary wastewater treatment applications for keeping lighter-than-water debris such as hair, food fiber, and synthetic fibrous materials from building up against the leading edge of the hollow tube (11) and clogging it.

  • Patent number: 9487425
    Abstract: Disclosed is a system and method for treating municipal and sanitary wastewater that uses only mechanical devices and processes, which eliminates biological processes and settling tanks. The system includes a three-output Richter-type separator that separates wastewater into three fluid streams according to the specific gravity of the solids within the fluid streams. The lighter-than-water and heavier-than-water solids streams are combined and the resultant sludge is mechanically dewatered without intermediary biological-process systems or sedimentation. The partially-clarified water component can be directly filtered by a membrane filter and optionally optically or chemically disinfected for reuse or disposal. The system advantageously simplifies municipal and sanitary wastewater treatment eliminating traditional primary and secondary treatment stages, and significantly reducing the system's operational footprint. The system and method can be scaled to very large municipal systems.

The device comprises a housing comprising at least one hollow spiral element with a conical shape, with separation openings being formed in at least some of the turns of the spiral element, each of the openings communicating with a corresponding separation chamber. Arranged opposite the separation opening is a nozzle, which is intended for compensating for the mass and centrifugal moment of the fluid medium. A guide element around which a flow passes is mounted on the wall of the nozzle. The cross-sectional area and the radius of each successive turn is selected from the condition for maintaining an estimated value for the centrifugal moment of the substance to be purified. The method consists in that a flow of medium to be purified is spun by the above-described device. Contaminating components in each turn are positioned by coaxial layers.

    Abstract: Systems and methods for separating sand and other solids from oil and other fluids produced from a well. The present systems and methods introduce the fluids at relatively high speed into a generally cylindrical separation chamber. The fluids flow in a generally circular path within the chamber, causing the solids and higher density fluid/media to be urged outward from the axis of the chamber as the fluids flow from the upper portion of the chamber. Because the solids become concentrated at the outer wall of the chamber, the fluid in a central portion of the chamber is substantially free of the solids, and can be removed from the chamber via a fluid outlet. The solids concentrated at the outer wall of the chamber continue to move downward into an accumulation chamber in which the fluid speed is reduced, allowing the solids to settle out of the fluid.

  • Patent number: 8926838
    Abstract: A process for the treatment of contaminated fluid and wastewater containing residuals from food processing and waste and residuals from animal feeding operations and effluent from the digestion of these residuals is disclosed. The process is carried out in an enclosed tank using a separation procedure that maintains the state of the separated solids in the same state as they were upon introduction to the system, i.e., aerobic, anaerobic or anoxic, based on the condition of the solids upon introduction to the system. The system utilizes rotary flow instead of rakes to harvest the solids from the effluent. The process has applications in the recovery of emulsion in wastewater treatment and the operation of digesters for re-feeding to the digester.

  • Patent number: 8919573
    Abstract: A system for purifying non-potable water to make said water potable includes an intake pump for bringing the non-potable water into the system. At least one centrifugal separator separates the non-potable water into suspended solids, saline water and oil. At least one ozone contact chamber injects ozone into a water stream being injected into at least one of the at least one of the centrifugal separators. A series of progressive filtration components are used for progressively filtering the saline water from the at least one centrifugal separator. The salinization filters then desalinate the progressively filtered saline water.

  • Publication number: 20140367348
    Abstract: Hydrodynamic separation of suspended particles using curved channels offers advantages in many applications, since it is a fast continuous flow technology that can handle neutrally and near neutrally buoyant particles without the need of a physical barrier or the addition of chemical aids. Designs are provided for a flow splitter at the end of the separation channel, to maintain smooth, counter-vortex-free laminar flow and improve particle separation efficiency while reducing clogging and fouling propensities.

  • Patent number: 8911635
    Abstract: It is disclosed a hydrocyclone type separator having small dimensions for possessing high capacity for fluid processing by virtue of structural characteristics for feeding, of an upper outlet orifice (overflow) and of a lower outlet orifice (underflow). The feeding comprises two equal channels (18), diametrically opposed and curved, wherein the transverse cross sectional area gradually diminishes for accelerating the two phase fluid stream in a moderate manner. The possibility of the connection of interchangeable devices (2) and (6) to the upper outlet orifice (13) permits changing the diameter of said outlet orifice and, in this manner, altering the hydrodynamic characteristics of the hydrocyclone and increasing the capacity of same to operational ranges suitable for fluid flows having high oil content, medium oil content and low oil content.

  • Patent number: 8906203
    Abstract: A system enables the use of solar heat energy together with electromagnetic energy and optionally energy produced during fermentation of organic products to produce fresh water from salt water, wastewater and water vapor contained in the atmosphere. The resulting fresh water can optionally be rendered drinkable by adding mineral salts at the desired concentration. A method and reactors combine electromagnetic and solar heating steps and optionally heat exchanges with a hot gas originating from combustion, to evaporate droplets of a spray produced from salt water or wastewater. The vapor obtained is separated from the salt particles or agglomerated impurities during evaporation using a cyclone system. The vapor can then be transported over a large distance before being condensed by bearings, in order to separate the water from any additives or impurities that may be present. Additives can be used to lower the vapor pressure of the liquid water and to facilitate droplet fractionation.
