Air-sparged hydrocyclone (ASH) technology for separation and environmental clean-up.

The original air-sparged hydrocyclone design used porous sintered steel or porous polyethylene tubes as spargers. To diminish/prevent plugging and to reduce pressure loss in the gas path, a wire screen sparger and new hydrocyclone design have been developed, allowing wide application of the technology in solving environmental problems and as a chemical reactor. Field and laboratory trials have shown that the technology might be preferred for stripping volatile compounds from contaminated water; it has also been developed for absorption of SO2 and toluene vapours and for the recovery of cyanide.
