MONTANA COLLEGE OF MINERAL SCIENCE AND TECHNOLOGY (Air-Sparged Hydrocyclone) TECHNOLOGY DESCRIPTION: The air-sparged hydrocyclone (ASH) was developed at the University of Utah during the early 1980s to achieve fast flotation of fine particles in a centrifugal field.
The objective of this research was to test a pilot-scale air sparged tank reactor (ASTR) and the ASTR in combination with a hydrocyclone (called the pilot-scale ASTR-hydrocyclone system) on two swine manure slurries for struvite-based (MgNH4PO4-6H2O) phosphorus removal and recovery.

A novel technology, air-sparged hydrocyclone technology, for removing oil and AFFF from wastewater is proposed. This is a newly developed technology by Advanced Processing Technologies, Inc. and it may provide an excellent opportunity to solve the problem.
Hydrocyclone is a continuous device that utilizes centrifugal force to accelerate the settling rate of particles. When feed slurry enters the hydrocyclone tangentially under pressure, as result of the high centrifugal forces, particles coarser than the "cut point" size migrate into a primary vortex ...

An air-sparged hydrocyclone apparatus and method, the apparatus including a substantially hollow, cyclone body having a cylindrical section and a downwardly oriented conical section. An inlet, an overflow and an underflow are also provided in the cyclone body. At least a portion of the wall of the cyclone body is modified to include an air-sparging section wherein air, under pressure, is ...
The air-sparged hydrocyclone (developed at the University of Utah) is a high-capacity flotation unit which is unique for the processing of phosphorites. The air-sparged hydrocyclone uses the high centrifugal force field and numerous freshly formed fine bubbles …
technologies. The major innovation in the area of centrifugal flotation is the Air Sparged Hydrocyclone (ASH), which has proven capabilities in achieving quality products at specific capacities greater than traditional flotation methods. However, the ASH technology ultimately …
• ZPM, Inc. was an industrial sponsor, and is actively engaged in commercialization of Air Sparged Hydrocyclone (ASH) technology in the field of industrial wastewater treatment. • Elbow Creek Engineering, Inc. was an industrial sponsor.
Air-sparged hydrocyclone flotation is a new technology that has been under development during the past decade. This technology combines froth flotation principles together with the flow characteristics of a hydrocyclone such that the air-sparged hydrocyclone system can perform flotation separations in a matter of seconds or even less.
The fine sands (55% - 400 mesh and 0. 01 opt) from gravity concentration were processed with a 5-cm air-sparged hydrocyclone (capacity 1. 0 t/h dry solids). Concentrate grades as high as 5. 0 opt were produced in a single stage at a recovery of 75%.
During the summer of 1992 the construction of the first 15-inch air-sparged hydrocyclone prototype was completed by the Advanced Processing Technologies, Inc. Installation at the Homer City Coal Preparation Plant was accomplished and testing began in October 1992.
Air - Sparged Hydrocyclone (ASH) was designed to enhance collisions of mineral particles with sparged gas bubbles and on this basis specific capacities of as much as 100 times those of traditional flotation equipment were achieved.

Development of a new technology using the air-sparged hydrocyclone (ASH) as a reactor for either cyanide recovery or destruction was the research objective. It was expected that the ASH could potentially replace the conventional stripping tower presently used for HCN stripping and absorption with reduced power costs.
Mar 05, 1991· (c) Air Sparged Hydrocyclone Separator . The principals of air-induced flotation separation may be employed in the environment of the hydrocyclone. The result is the air-sparged hydrocyclone. In air-sparged hydrocyclone flotation, a separator vessel …
The flotation tests were carried out in a 1-l Denver-type flotation cell and in a 2-inch diameter air-sparged hydrocyclone (ASH). The flotation concentrate from the air-sparged hydrocyclone contained 35% coke by weight on a dry basis, with a coke recovery to the concentrate of 54%.
