Acoustophoretic devices are disclosed. The devices include a flow chamber, an ultrasonic transducer, a reflector, an inlet, a filtrate outlet, a concentrate outlet, and optionally a lipid collection trap. The ultrasonic transducer and reflector create a multi-dimensional acoustic standing wave in the flow chamber that traps and separates red blood cells and/or lipids from blood. Concentrated red blood cells can be recovered via the concentrate outlet, the lipids can be recovered via the lipid collection trap, and the remaining blood can be recovered via the filtrate outlet. Methods for separating blood components (e.g., red blood cells, lipids, platelets, white blood cells) from blood are also disclosed. The red blood cells can undergo washing with a solvent to remove undesired admixtures. Cryoprotectants can be added or removed from the blood.

Various techniques are provided in relation to flocculation and/or dewatering of thick fine tailings, with shear conditioning of flocculated tailings material in accordance with a pre-determined shearing parameter, such as the Camp Number. One example method of treating thick fine tailings including dispersing a flocculant into the thick fine tailings to form a flocculating mixture; shearing the flocculating mixture to increase yield stress and produce a flocculated mixture; shear conditioning the flocculated mixture to decrease the yield stress and break down flocs, the shear conditioning being performed in accordance with the pre-determined shearing parameter to produce conditioned flocculated material within a water release zone where release water separates from the conditioned flocculated material. The conditioned flocculated material can then be subjected to dewatering, for example by depositing, thickening or filtering. The design, construction and/or operation of a flocculation pipeline assembly can be facilitated.

The present disclosure relates to methods and devices for the separation of blood components including separation by rapid sedimentation, including in an automated fashion.

A shot peening apparatus includes a first tank. The first tank includes a swirl flow generating mechanism and a suction port. The swirl flow generating mechanism swirls a waste liquid in the circumferential direction. The suction port is disposed at the axial center of the first tank. The suction port opens toward a bottom wall and suctions the waste liquid. A plurality of blade members are provided inside the first tank. The plurality of blade members hinders the waste liquid from swirling in the first tank.

Methods for breaking polymer-containing treatment fluids for use in subterranean formations are provided. In one or more embodiments, the methods comprise providing a treatment fluid comprising a base fluid and a polymer, wherein the treatment fluid was used to treat at least a portion of a subterranean formation; and sonicating at least a portion of the treatment fluid to at least partially reduce the viscosity of the treatment fluid.

Disclosed is a rake-free thickening device including driving area. The device includes a feed assembly, a diversion assembly and a clean coal collection assembly. The clean coal collection assembly includes a driving area. The diversion assembly includes a central tank. Slime water passes through the feed assembly and flows with a medicament from an upper part of the central tank to a middle of the central tank, and then diffuses around. Bubbles carry the fine slime up after reacting. The driving zone drives the dispersed bubbles to a defoaming zone located in the middle of the central tank. The slime water in the central tank flows through the central tank after defoaming. With the continuously filling of slime water, the slime water above the central tank overflows the central tank to the clean coal collection assembly within the diversion and settlement area.

A single stage clarifier and mixing assembly includes a housing, a mixing section within the housing and a clarifier section within the housing. The mixing section includes a mixing chamber having (a) an inlet, adapted for delivering an inlet stream to the mixing chamber, at an upper end, and (b) a mixing section outlet at a lower end. The clarifier section extends concentrically around the mixing section. The single stage clarifier and mixing assembly also includes an agitator adapted for mixing the inlet stream in the mixing chamber.

A single stage clarifier mixing assembly includes a housing having a circular sidewall and a center axis, a mixing section in the housing, a clarifier section overlying and axially aligned with the mixing section along the center axis within the housing, an inlet delivering an inlet stream to the mixing section and an agitator. The agitator is adapted for mixing the inlet stream in the mixing chamber.

A multipurpose wheel-washing apparatus includes a wheel-washing unit including an upper frame provided with a plurality of rollers on which wheels of a vehicle are to be rotatably seated, and injection nozzles configured to inject high-pressure washing water onto the wheels seated on the rollers; and a lower frame provided with a water tank located below the upper frame so as to collect falling waste/turbid water; a water storage unit configured to store washing water to be supplied to the injection nozzles; a purification unit configured to receive and purify the waste/turbid water from the water tank and then send purified water to the water storage unit; and a blowing unit disposed on an exit side of the wheel-washing unit so as to blow air and provided with spray nozzles for selectively spraying water in a particulate form. Accordingly, environmental pollution can be significantly reduced.
