PCB Removal

Dynamic Adsorbents Inc. (DAI) has formulated a specialty adsorbent for the removal of PCBs from contaminated sites. Alumina C is a chemically and physically modified form of alumina with highly favorable properties for the collection and isolation of PCBs from the environment. During chromatography, PCB contaminated media is passed through a column packed with Alumina C. PCBs are separated from the media by the adsorption action that takes place when PCBs come into contact with the Alumina C, resulting in a PCB-free environment. The captured PCBs remain in the column with the alumina and may be disposed of using appropriate destruction technology. The use of this potent adsorbent serves as an efficient means to gather PCBs in one location, subsequently aiding destruction technologies in dechlorinating these hazardous compounds.

Using Alumina C for PCB removal is advantageous in many ways. First, the system is transportable and can be taken directly to the contaminated sites in need of clean-up. With this technique, there is no need for a physical plant to be established, eliminating high operating costs. Furthermore, there is no high energy cost involved because there are no high pressures or temperatures utilized during the process. The PCBs collected by Alumina C are gathered in one location and may be safely carried to their final disposal site. Moreover, the reagent is reusable, allowing for efficient use of all materials. Although chromatography uses batch processing rather than continuous in-line processing, this universal technique is proven to provide superior separation capabilities. Chromatography using Alumina C is a powerful separation technique incomparable to other methods.
