Activated carbon adsorption has become a standard procedure for the cleanup of contaminated water streams. To facilitate such cleanup at hazardous waste and spill sites, mobile carbon adsorption units have been constructed and are now in use. Their primary drawback is the logistics associated with the disposal of spent (contaminated) carbon and its replenishment with fresh, active carbon. The program was undertaken to assess the feasibility of designing and building a mobile carbon regeneration unit - including an incinerator/scrubber to destroy the offgases - for field use in conjunction with mobile carbon adsorption systems. A system was designed and built based on technology developed in the earlier fabrication of a laboratory-sized regenerator and on an in-depth evaluation of factors affecting system design and size. Housed in a standard van-type of trailer, the system met all weight and size limitations for over-the-road transportation. The system includes a direct fired, rotating barrel kiln to thermally regenerate the carbon, an incinerator and scrubber to destroy the desorbed materials and treat the off-gases, and a separator to reclaim the reactivated carbon granules. Test runs using spent carbon from an on-site treatment of a spill were quite successful. The carbon was returned to essentially 1005 activity with an 88% volume recovery. The unit has been delivered to the US EPA for their use.
