"INVESTIGATION OF AN INEXPENIVE MOBILE BIOLOGICALLY ACTIVE AIR FILTRATION (BAF) UNIT FOR VOLATILE ORGANIC (VOC) COM- POUNDS"

INCREASED EMPHASIS ON THE PROBLEMS ASSOCIATED WITH ING UNDERGROUND STORAGE TANKS AND UNDERGROUND POLLUTION IN GENERAL HAS CREATED A NEED FOR TECHNOLOGY TO REDUCE OR ELIM-INATE THE ASSOCIATED CONTAMINATION. TO DATE, PACKAGE AIR GENERAL HAS CREATED A NEED FOR TECHNOLOGY TO REDUCE OR ELIMINATE THE ASSOCIATED CONTAMINATION. TO DATE, PACKAGE AIR STRIPPING UNITS SEEM TO HAVE RECEIVED THE BROADEST AC- CEPTANCE AS THE PREFERRED APPROACH FOR REMOVING VOLATILE ORGANIC COMPOUNDS (VOC) FROM CONTAMINATED WATER. THESE UNITSREMOVE VOC FROM WATER BY STRIPPING THEM IN AN AIR STREAM AS CONTAMINATED WATER FALLS DOWN OVER A POROUS MEDIUM TO IN- CREASE SURFACE AREA. THE RESULTING CONTAMINATED AIR I EITHER VENTED DIRECTLY TO THE ATMOSPHERE OR IS PASSED THROUGH EXPENSIVE ACTIVATED CARBON COLUMNS TO REMOVE CON- TAMINANTS ENVIRONMENTAL TECHNOLOGY SOUTHEAST, INC. IS DEVELOPING A ALOW COST BIOLOGICAL ACTIVE AIR FILTRATION UNIT (BAF) TO REPLACE ACTIVATED CARBON IN THIS APPLICATION OR TO EN- HANCE THE USEFUL LIFE OF ACTIVATED CARBON THROUGH USE AS A TREATMENT STEP PRIOR TO ACTIVATED CARBON. THE FILTER IS COMPRISED OF AN ORGANIC MEDIUM WHICH EXHIB- ITS AN ABSORPTIONAFFINITY FOR VOC. THE MEDIUM IS SEEDED VOC DEGRADATION. IT IS ANTICIPATED THAT THE MICROBES WILL ACT TO CONTINUALLY REPLENISH ACTIVE ABSORPTION SITES WITH-
