A separation tank for the separation of a mixture of oil, gas, water, and solids obtained from an oil field includes distinct regions vertically located within the tank interior where constituent components of the mixture can collect. The inflowing mixture may be directed to a vertical column extending inside the separation tank and can be introduced to the tank interior through a swirl vane diffuser configured to impart a helical direction to the inflowing mixture that assist separation of the mixture component. To further facilitate separation of oil from the mixture, the separation tank may be operatively associated with an aeration system configured to generate and introduce an aerated liquid to the tank interior. Gas dissolved in the aerated liquid may form microbubbles that can naturally adhere to the oil and solids separate it from the mixture which can improve the quality of the water.

An apparatus for gas and solids separation from down-hole fluids having an inner tube and an outer tube disposed about the inner tube. The annular region between the tubes contain a plurality of chambers, separated by fluid barriers. The chambers include an intake chamber to receive fluids from outside of the outer tube through an orifice, and processing chambers. Fluid communication between the intake and processing chambers is restricted to fluid flow through sets of tubes. Fluid communication between a lowermost processing chamber below the intake chamber and a lower processing chamber above the intake chamber is restricted to fluid flow through the inner tube. A block restricts fluid communication within the inner tube to other chambers above the intake chamber. Orifices in the inner tube of the processing chambers on either side of the block provide fluid communication across the block.

The present invention discloses an oil-contained wastewater treatment apparatus applying the integrative physical methods. The wastewater treatment system of the invention may include a main tank, where the upper part is a rectangular body and the lower part is designed to a multi-bucket bottom structure. Two oil collection boxes are arranged to both outside ends of tank. A mud discharging outlet is attached to the bottom of the tank. Meanwhile, both of a water outlet and an electric polarizer are localized at the end face of the effluent on the tank. A power supply for the electro-adsorber is fixed to the inlet end on the top face of the tank. Divided by upper and lower deflectors, the inside of the tank is divided to three processing units, i.e., sludge-water separation unit, degradation-coalescence treatment unit, and sedimentation-electric polarization unit. Vortex centripetal gas flotation is applied to remove oil. Electro-adsorption induces the micelle clustering to achieve the decolorization. The electric polarization functions as anti-scaling, descaling, sterilization, and corrosion inhibition. Moreover, the referred physical treatment can be fulfilled in virtue of centrifugal force, buoyancy, gravity, adsorption force, coalescence force, inertia, shifting, and modification. Through the application of the system, the oil-contained wastewater can be treated environmentally friendly, safe and pollution-free. Besides the above advantages, high removal efficiency can make the apparatus and method a widely used approach on the oil-contained wastewater treatment.

An apparatus for separating particles from a particulate suspension comprises a conduit comprising a plurality of elongate channels extending in adjacent alignment along a spiral path at different curvature radii from an axis of the spiral path. Longitudinal sidewalls of the elongate channels are fluidly joined together to allow for transfer of fluid between them. The apparatus also comprises an inlet for directing a particulate suspension into the conduit and outlets that direct fluid from the particulate suspension out from different discharge positions. At least first and second of the elongate channels are approximately circular in cross section and comprise a shared longitudinal sidewall, wherein the shared longitudinal sidewall comprises opposed uppermost and lowermost sidewall sections that are laterally offset from one another relative to the axis of the spiral path to allow for transfer of helically flowing fluid between the first and second of the elongate channels.

The present disclosure relates to settling devices for separating particles from a bulk fluid with applications in numerous fields. The particle settling devices of the present disclosure may include a stack of truncoconical cones that may be arranged in opposite orientation, apex to base. Other embodiments include several concentric vertical tubes attached to conical surfaces at the bottom, with inclined settling strips attached to the vertical tubes in annular regions between the tubes. These devices are useful for separating small (millimeter or micron sized) particles from a bulk fluid with applications in numerous fields, such as biological (microbial, mammalian, plant, insect or algal) cell cultures, solid catalyst particle separation from a liquid or gas and waste water treatment.

The present invention relates to an apparatus and a method of cleaning particle loaded “dirty” air using a multi flow-splitter technology in combination with at least one cyclone system which requires minimal energy to operate due to low pressure drops used to generate the fluid flows whilst allowing to exert high centrifugal or G-Force on the infeed fluid stream. This further allows to operate the particle removal process such that conventional additional filter media become optional, such that the technology may operate a significantly reduced or even without the need for maintenance and/or repair. Low internal air turbulence ensures a very high separation efficiency. Optionally adding additional explosion safe low-energy down-stream filtration stages with variable speed system fan provides optimal operational performance and operational flexibility.

A solid-liquid separator including a hollow structure. The hollow structure may include a separator portion having a solid-liquid-mixture inlet and a curved-funnel-shaped inner separator surface. The hollow structure may further include a collector portion having a frustoconically-shaped inner liquid guide surface. The separator portion and the collector portion may be disposed such that a spout of the curved-funnel-shaped inner separator surface and a narrower end of the frustoconically-shaped inner liquid guide surface may be directed towards each other.

The invention in at least one embodiment includes a system for treating water having an intake module, a vortex module, a disk-pack module, and a motor module where the intake module is above the vortex module, which is above the disk-pack module and the motor module. In a further embodiment, a housing is provided over at least the intake module and the vortex module and sits above the disk-pack module. In at least one further embodiment, the disk-pack module includes a disk-pack turbine having a plurality of disks having at least one waveform present on at least one of the disks.

A fluid filtration assembly (FFA) includes a housing having a thickness defined between an internal surface and an external surface, the housing receiving a filter and defining an outer annular flow passage between an outer surface of the filter and the internal surface of the housing; an inlet pipe communicates with the FFA and injects a fluid into the housing to impart a centrifugal force; an outlet pipe communicates with the FFA and discharges the fluid from the housing; and a collection area disposed towards an end of the outer annular flow passage collects particulate matter from the fluid; wherein a width of the outer annular flow passage increases towards the collection area.

Apparatus for separating grit from a grit-loaded liquid matrix while retaining organic solids in suspension, including an inlet for admitting liquid matrix into the apparatus, an outlet for removing grit-lite liquid matrix from the apparatus main chamber, and a vortex system for removing separated liquid matrix grit from the apparatus. The grit settling main chamber defines upper and lower subchambers communicating with each other through a central aperture. A fluid flow speed gradient is established between the apparatus fluid inlet and outlet. An Eddy type fluid dynamic component is added, providing combined enhanced coarse grit and fine organics discrimination and separation. The Eddy fluid dynamic component may consist of a trio of stationary fresh water supply force fed eductors. Each eductor produces a fresh water fluid flow interacting with the liquid matrix fluid flow inside the upper subchamber, whereby Eddy-type turbulences are generating promoting fine, liquid matrix grit particle separation from the liquid matrix.
