A separation system is presented that partitions a slurry containing a plurality of particles that are influenced by a fluidization flow (which comprises teeter water and gas bubbles) and a fluidized bed. The separation system comprises a separation tank, a slurry feed distributor, a fluidization flow manifold and a gas introduction system. All of these components are arranged to create the fluidized bed in the separation tank by introducing the slurry through the slurry feed distributor and allowing the slurry to interact with the fluidization flow that enters the separation tank from the fluidization flow manifold. The gas introduction system is configured to optimize the gas bubble size distribution in the fluidization flow. The gas introduction system comprises a gas introduction conduit and a bypass conduit. The gas introduction system can be adjusted by modulating the flow of teeter water through the gas introduction conduit.

Disclosed is high-ash fine coal slime separation equipment and method, applicable to the field of coal washing. The high-ash fine coal slime separation equipment includes a feeding system (1), a mineralization system (2), a separation system (3) and a pulsating water flow control system (4). A coal slime mineralization region is isolated from a separation region; and a damping block and a pulsating water flow device are arranged in a mineral separation system. A flotation feeding is fed into the feeding system (1), slurry mixing operation is completed, coal slime enters the mineralization system after pulp mixing to generate turbulent collision to form mineralized bubbles, the mineralized bubbles enters the separation system (3) after passing through a turbulent-flow dissipation pipe (12), and meanwhile, pulsating water flow with a certain frequency and waveform is fed into the separation system (3) by the pulsating water flow control system (4).

In a method and apparatus for separating low density particles from feed slurries, a bubbly mixture is formed in a downcomer and issues into a mid region in a chamber. An inverted reflux classifier is formed by parallel inclined plates below the mid region allowing for efficient separation of low density particles which rise up to form a densely packed foam in the top of the chamber, and denser particles which fall downwardly to an outlet.

Flotation separation apparatus and methods are described herein, comprising a vessel having a plurality of flow guides oriented vertically in the vessel, a liquid inlet at a lower part of the vessel, a gas inlet at the lower part of the vessel, a first liquid outlet at an upper part of the vessel, a second liquid outlet at the lower part of the vessel, and a gas outlet at the upper part of the vessel.

The present disclosure relates to a separation device to separate contaminants from contaminated water. It comprises a container to receive the contaminated water. The container further comprises a contaminated water inlet, a filter, a presser for compressing and/or dewatering contaminants separated from the contaminated water, and a contaminant outlet. The container further comprises a gas inlet for generating gas bubbles into the contaminated water to further separate contaminants from the contaminated water. The present disclosure relates to a use of such a separation device and a method of separating contaminants from contaminated water.

Water contaminated with antibiotics, pharmaceuticals, microorganisms and other organic material stripped of these contaminating products with a specialized gas sparged hydrocyclone apparatus using an ozone containing gas as the stripping gas. The stripping gas contains 50-98 volume percent ozone, and the contaminated water is exposed to UV light prior to introduction into the sparger.

A method and enhancements for the decontamination of water containing one or more PFAS contaminants includes introducing a foaming agent into the water, and injecting a gas through a diffuser and into the water so as to form a plurality of bubbles in the water, the one or more PFAS contaminants accumulating on the plurality of bubbles. The plurality of bubbles is allowed to rise, forming a foam at the surface of the water. The resulting foam is then collected and transported away from the surface of the water, where it condenses into a liquid and is treated to regulatory standards.

Flotation separation apparatus and methods are described herein, comprising a vessel having a plurality of flow guides oriented vertically in the vessel, a liquid inlet at a lower part of the vessel, a gas inlet at the lower part of the vessel, a first liquid outlet at an upper part of the vessel, a second liquid outlet at the lower part of the vessel, and a gas outlet at the upper part of the vessel.

A tank for removing sand entrained in a flow includes an inlet assembly including churn tubes configured to receive fluid provided into the tank such that sand is separated from water, gas and oil present in the flow. An oil outlet port communicates with an oil collection device, and a water outlet port communicates with a water outlet assembly.

The present invention provides an apparatus and method for feeding a feed slurry into a device for separating low density particles from the feed slurry. The apparatus comprises a conduit having a slurry inlet, a gas feed inlet, a plurality of hollow tubes and an outlet. The hollow tubes are configured to combine the feed slurry from the slurry inlet and gas from the gas feed inlet. The hollow tubes comprise a porous section to generate bubbles of substantially uniform size into the slurry for adhering to the low density particles. Slurry flows in axially aligned hollow tubes as gas is introduced through the porous sections into the slurry. Alternatively, slurry flows around hollow tubes arranged perpendicular to the conduit longitudinal axis as gas is discharged through the porous sections into the slurry.
