Operating Experiences at VOC Treatment Facilities Part 2: Air Stripping

Abstract

In 1991, the Organic Contaminants Control Committee of the American Water Works Association Water Quality Division completed a report on 68 air stripping and granular activated carbon (GAC) treatment facilities in the United States. In a followup, the committee contacted each facility to obtain operating experiences and operation and maintenance costs associated with the use of these technologies to remove volatile organic chemicals (VOCs) from drinking water. The committee's followup findings are summarized in this two‐part article. Part 1, which appeared in last month's Opflow, presented the findings regarding the GAC facility questions; Part 2, which follows, highlights the air‐stripping facility findings.
