Abstract
A series of laboratory tests and an on-site pilot scale demonstration of Bio-Recovery Systems' AlgaSORB technology for the removal and recovery of mercury-contaminated groundwater were conducted under the SITE program. Optimum conditions were determined for mercury binding to AlgaSORB. Conditions under which mercury could be stripped from AlgaSORB were developed. On-site, pilot scale demonstrations with a portable waste treatment system incorporating columns containing two different AlgaSORB preparations confirmed laboratory tests. Over 500 bed volumes of mercury-contaminated groundwater could be successfully treated before regeneration of the system was required. Mercury was removed to levels below the discharge limit of 10 microgram/L.
