Potential of air-sparged hydrocyclone flotation in environmental technology

Journal ArticleAir-sparged hydrocyclone (ASH) flotation is a high capacity flotation technology originally developed in the Department of Metallurgical Engineering at the University of Utah for processing mineral resources. However, the technology has been found to be useful in industrial waste processing, recycling for the recovery of secondary resources, and in remediation of environmental disasters. For example, areas in which the ASH technology has demonstrated potential include: cleaning of waste coal fuels, air stripping to remove volatile organics from drinking and process water, water disinfection by ozone or chlorine sparging, dispersed oil removal from water, and contaminated soil remediation
