Abstract
Evaluates the ability of ultra-light filter media for removing ferric?arsenic floc formed with coagulation. Evaluates the ability of the ultra-light media to be adequately and consistently backwashed at much lower backwash rates compared to those of conventional sand?anthracite media. Demonstrates the long-term operational stability and performance of the ultra-light media in a coagulation?filtration process for arsenic removal from groundwater. Research partner: AWTP.
