摘要:
Foam mitigation using a variety of articles, systems, and methods is generally described. According to certain embodiments, surfaces with certain wetting properties can be used to reduce or eliminate the formation of foam from bubble-containing liquids. In some embodiments, a surface with certain wetting properties is configured and/or arranged within bubble-containing liquids such that the surface provides a gaseous fluidic pathway through which gas from the bubbles within the liquid may be channeled to a gaseous environment outside the liquid.

A method for treating produced water from a fracking operation is disclosed. The produced water is first fed to a compact separator for the removal of suspended materials. This produced water is then treated for dissolved gases and suspended oils before being fed to a crystallizer where salts are separated from the produced water thereby producing fresh water for reuse or other means. Alternatively, the produced water may be fed to a disinfection system and a concentrator depending upon the composition of the produced water.

A gas-liquid separator includes a fluid inlet, a shell including an inside surface enclosing an interior space, an outlet structure with fingers converging toward a longitudinal axis, and a dripper including a dripper tip. The fingers terminate at fingertips located proximate to an outside surface of the dripper. Gas exit ports are defined between adjacent fingers, and by the dripper. The gas-liquid separator defines a liquid flow path from the fluid inlet, along the inside surface, along one or more of the fingers, converging along the dripper outside surface, and to the dripper tip. The gas-liquid separator also defines a gas flow path from the fluid inlet, through the interior space, and through the gas exit ports. The gas-liquid separator may be utilized in fluid separation systems such as liquid chromatography or supercritical fluid chromatography/extraction systems.

An aquarium filtering and purifying system includes an upper display tank and a lower filter tank. The water from the upper tank can be delivered to the lower tank to a filter, such as within a surrounding filter fabric or membrane, such as a filter sock. An air tube can also be inserted into the filter tank to an unfiltered side of the filter, such as within the filter sock, to deliver air bubbles into the filter tank. The air tube can have an air stone at the end thereof to diffuse the air bubbles. Further air stones can be provided on an outside of the sock in the first compartment. Filtered water is delivered to a second compartment in the filter tank. The next compartment can have sand, and/or rocks and/or algae and/or a clean-up crew to assist in purifying the water. Water from the second compartment then passes to a third compartment, through a bubble trap, and then is pumped back to the display tank. Alternatively, the first compartment can be provided with a macro algae bed instead of a filter sock.
摘要:
A system for separating a flow of matter is shown and described. The system includes one or more flow separation devices, one or more surgical instruments, and one or more suction sources. In some embodiments, the flow of matter comprises biological material. In some embodiments, the flow of matter comprises surgical waste.

Embodiments of the present invention include a backscatter reductant anamorphic beam sampler. The beam sampler can be implemented to measure a power of a reference beam generated by an electromagnetic radiation source in proportion to a power of a working beam. The beam sampler can provide astigmatic correction to a divergence of the working beam along one axis orthogonal to a direction of propagation. The beam sampler can further be implemented to prevent backscatter from impinging upon a photodetector of the beam sampler resulting in a reduction of error and instability in measurements taken by the beam sampler.
摘要:
A degasser (10) includes a vessel (12) having a series of chambers (18,20,22,24). Liquid containing a gas is directed through the vessel (12) and the chambers (18,20,22,24) therein. A stripping gas is injected into the vessel (12) and moves through the vessel in a counter-current direction relative to the flow of liquid. More particularly, the stripping gas moves from one chamber to another chamber in an upstream direction (relative to the flow of the liquid) and is mixed with the liquid in each chamber (18,20,22,24), causing gas in the liquid to be displaced. Displaced gas is vented from the vessel (12) at a location near where the liquid enters the vessel (12).
摘要:
An apparatus (12) for treating water, in particular for removing surfactants from waste water, includes a vessel (14), defining an inlet (16) for receiving waste water containing air bubbles, and an outlet (20) for the exit of water, following treatment. Inside the vessel there is at least one tubular member (50) having a lower open end (52) into which the flow of waste water from the inlet may be directed in use. The tubular member (50) extends from the inlet towards a top of the vessel where an upper exit (54) from the tubular member is defined. In use, most un-aerated water entering the vessel through the inlet can exit the tubular member at the lower open end. Foam formed in the water by the air bubbles may travel up the tubular member to the upper exit, which is preferably located above the water level (60) in the vessel.
摘要:
The present invention relates to a device and a method for separating bubbles from a fluid comprising a chamber through which a fluid can pass. According to the invention the device is characterized in that the inner chamber wall has a geometry that generates within said chamber a continuous flow and at least one area with a discontinuous flow which has a low flow velocity so that bubbles remain at the inner chamber wall in said area and thus are separated from the fluid flowing out from the chamber.
