How Can Alumina Be Used for PCB Removal?
Dynamic Adsorbents Inc. (DAI) has
formulated a specialty proprietary adsorbent (Alumina C) allowing PCBs
to be removed safely 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. Using industrial size batch
chromatography, PCB contaminated soil and other environmental waste is
passed through columns packed with Alumina C. PCBs are separated out
through the adsorption process which occurs when PCBs come into contact
with Alumina C. The captured PCBs remain in the column attached to the
alumina. This bonded material then contains virtually all of the PCB
material and the alumina bonded adsorbent 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 which may subsequently be
used to dechlorinate these hazardous aromatic compounds.
Using Alumina C for PCB removal
had been demonstrated to be advantageous. Batch chromatographic
purification systems are transportable and are taken directly to the
contaminated sites in need of clean-up. Using this technique there is no
need to build a physical plant eliminating high operating costs. Energy
requirements are low, with no high pressure or high temperatures being
utilized. PCBs collected (eluted) and bound to Alumina C are gathered in
one location and then safely carried to their final disposal site. While
chromatography uses batch processing rather than continuous in-line
processing this technique is proving to provide superior separation
capabilities.
