Removal of volatile organic compounds from contaminated water using air-sparged hydrocyclone stripping technology

The air-sparged hydrocyclone (ASH) technology offers the unique opportunity to achieve efficient removal of volatile organic compounds (VOCs) from contaminated water at a high specific capacity, more than 100 times that of conventional air stripping technologies. VOC stripping is the first application of the ASH as a contacting reactor rather than a flotation device. The effectiveness of the ASM system for this application has been demonstrated through a number of experiments. Results from these teste show that the ASH technology is very competitive with other stripping technologies and that single stage contaminant removal exceeding 90% can be achieved.
