An evaluation of Calgon F-400 and Ambersorb 563 and 572 and XAD-4 resins for removal of VOCs from an activated sludge treated groundwater was performed using continuous flow reactors. Breakthrough and EBCT-ST curves were developed and the capacities of the adsorbents were determined. Comparison of the performance of the adsorbents indicated that: (1) Ambersorb 563 resin provided greater VOC adsorption capacity and run-time to breakthrough than Ambersorb 572 and XAD-4 resins or the F-400 GAC. (2) Ambersorb 563 resin could also be operated at three times the surface loading rate of the GAC system resulting in smaller equipment size. (3) The Ambersorb 563 resin showed negligible TOC removal despite a high specificity for the target organic analytes. A cost analysis indicated that the installed cost for a 6.31 L/s Ambersorb 563 resin system was 2.8 times the cost of a F-400 GAC system. The annual operating cost however, was four times lower and the total present worth was $549,000 less.
