Application of Ambersorb 563 adsorbent technology for treatment of chlorinated organics in groundwater
- Roy F. Weston, Inc., West Chester, PA (United States); and others
Roy F. Weston, Inc. (WESTON{reg_sign}), in conjunction with Rohm and Haas Company (Rohm and Haas), conducted a field pilot study to demonstrate the technical feasibility and cost-effectiveness of Ambersorb{reg_sign} 563 (A-563) carbonaceous adsorbent for the remediation of groundwater contaminated with volatile organic compounds (VOCs). The project was conducted under the Emerging Technology Program of the EPA Superfund innovative Technology Evaluation (SITE) program. Ambersorb adsorbents are a family of patented, synthetic, tailorable carbonaceous adsorbents that were developed by Rohm and Haas in the 1970`s for the treatment of contaminated water. In specific applications, Ambersorb adsorbent technology may offer a cost-effective alternative to air stripping or granular activated carbon (GAC), which are typically used in pump and treat systems for remediating groundwater contaminated with organic compounds. Ambersorb adsorbents have been found to be effective in the removal of low levels of VOCs and other synthetic organic compounds from contaminated water. Previous applications using Ambersorb adsorbents have demonstrated several key performance benefits over GAC. Ambersorb 563 adsorbent can be regenerated onsite using steam, solvents, or other techniques, permitting the recovery of a concentrated organic stream which can be disposed of or reclaimed. Ambersorb 563 adsorbent has a significantly greater adsorption capacity than GAC for chlorinated hydrocarbons when the contaminants are present at low concentrations. Ambersorb 563 adsorbent systems can operate at higher flow rates than GAC systems, white maintaining effluent water quality below drinking water standards.
