Ancillary embodiments and modifications to a homogenizer unit (“PPH”), and methods of use directed to purification of biogas or other raw methane streams. The apparatus includes a homogenizer body, one or more stream inlets (for the raw methane), one or more chilled water inlets, a mixing zone where the water stream is commingled with the raw methane stream, and a venturi immediately downstream from the mixing zone such that the commingled streams are pulled into the venturi resulting in homogenization. The PPH components are insulated to maintain the chilled water of the various streams at a cooled, below ambient temperature, increasing dissolution of the contaminant gases into the chilled water, and producing a purified methane stream including little or no H.sub.2S and CO.sub.2.

An apparatus for generating and mixing gas bubbles into an aqueous solution includes a structure defining an interior fluid-flow chamber extending along a longitudinal axis between a liquid input end and a liquid output end. The structure is characterized by a gas injection portion and a mixing vane portion. The gas injection portion is located downstream from the liquid input end and upstream from the liquid output end. The gas injection portion defines a first region of the interior fluid-flow chamber and a gas injection lumen that is surrounded by the interior fluid-flow chamber. The gas injection lumen, which extends along a length of the gas injection portion, is configured to inject gas from the interior of the gas injection lumen into the surrounding interior fluid-flow chamber. The mixing vane portion extends in the downstream direction from the gas injection portion and define a second region of the interior fluid-flow chamber.

The device is a gas-liquid mixing device having a venturi structure in which a throat portion and an enlarged diameter portion are provided in a main passage through which a liquid passes, the gas-liquid mixing device including a collision chamber provided on an outer periphery of the enlarged diameter portion, and a stirring chamber provided downstream of the enlarged diameter portion. A collision flow path communicating with the collision chamber and causing a gas-liquid to collide with an outer peripheral wall, a straight flow path through which the gas-liquid passing through a central portion of the enlarged diameter portion travels straight, and an outer ring flow path through which the gas-liquid flows from the collision chamber to the stirring chamber are formed downstream of the enlarged diameter portion. The gas-liquids from the outer ring flow path and the straight flow path are stirred in the stirring chamber.

A compressed air foam mixing system that has a mixing device connected to a discharge port of a tank. The mixing device receives fluid from the tank and pressurized air from the tank or alternatively directly from a source of pressurized air. The fluid and pressurized air are combined within the mixing device to form a foam.

A water processor is provided for processing or conditioning water to be distributed downstream of the water processor. The water processor includes a housing having an inlet and an outlet opposite the inlet. The water processor includes a conditioning element disposed inside of the housing between the inlet and outlet. The conditioning element includes a plurality of plates having apertures with sharp edges to direct the flow of water and facilitate splitting of small gas bubbles into even smaller nano-bubbles. The plurality of plates include a first plate having a first configuration of apertures and a second plate having a second configuration of apertures. The first and second plates are disposed in alternating spaced arrangement along the longitudinal axis of the housing. The second configuration is different from the first configuration such that the flow path through the water processor is circuitous or substantially indirect.

A transportable system for creating an oxidation reduction potential (ORP) in water employs a pipe assembly for in-line mixing. The pipe assembly includes a first flow path for water to flow through. The first flow path includes one or more ozone intake ports that are fluidically coupled to one or more ozone output ports of an ozone supply unit. The pipe assembly further includes a second flow path fluidically coupled in parallel with the first flow path. The second flow path includes a control valve that selectively permits a portion of the water to flow through the second flow path to produce a negative pressure in the first flow path so that ozone is drawn into the first flow path through the one or more ozone intake ports and mixed into the water flowing through the first flow path.

An object of the present disclosure is to improve the generation efficiency of a UFB-contained liquid in a generation apparatus having a circulation mechanism. One embodiment of the present invention is an ultra fine bubble generation apparatus including: a first tank that stores a liquid; a generation unit configured to generate an ultra fine bubble in the liquid output from the first tank; a second tank that stores the liquid output from the generation unit; and a liquid passage that inputs again the liquid stored in the second tank to the first tank, and the ultra fine bubble generation apparatus includes a blocking configuration that blocks an ultra fine bubble included in the stored liquid from being input again to the first tank.

A flow management and separation system for a horizontal wellbore having a primary artificial lift device having an intake has (a) a sealed central flowpath from a fluidseeker weighted keel inlet, through a recovery flow tube, a seal bore extension and a dip tube having a pump intake sealing assembly in fluid communication with the lift device intake; and (b) a mixed fluid flow path from a fluidseeker internal bypass passage, through an annulus of at least one slug catcher comprising a perforated shell.

Provided is an ultrafine bubble generating method and an ultrafine bubble generating apparatus capable of efficiently generating a UFB-containing liquid with high purity. To this end, a flow passage inner volume is varied by using a flow passage inner volume varying element, the liquid is pressurized such that the liquid passes through a narrow portion at high speed and flows into a depressurizing area.

An ozone injector device comprising a housing having a water passageway through the housing, a corona tube disposed within the housing and configured to generate ozone, an ozone inlet fitting removably coupled to the water passageway, the ozone inlet being in fluid communication with the corona tube via a corona discharge tube, and a spring-loaded clearing piston positioned to move into and out of the water passageway directly opposite the ozone inlet. The clearing piston is biased upwards, towards to the ozone inlet, and configured to prevent flow of ozone into the water passageway.
