Abstract:
A system for recovering and recycling HAP/VOC contaminants from a contaminated air stream using bioremediation, comprising:a reservoir having a lower tank portion in which a first water bath is maintained;a filter structure containing a capture material therein, said filter structure being fixedly mounted over a top portion of said reservoir; andmeans for spraying a second water bath over said filter structure;wherein said first and second water baths are composed of microbe-inoculated volumes of water, said volumes of water being inoculated with a predetermined type of microorganisms having an affinity for the contaminants to be processed, andwherein said reservoir, said filter structure and said spraying means are positioned relative to one another whereby the contaminated air stream flows into said reservoir and a portion of the contaminants are leached into said first water bath in the lower tank portion, the remaining contaminants are filtered through said filter structure and are captured in the filter structure, after which said second water bath is sprayed from said spraying means down through said filter structure to leach the captured contaminants and direct said leached contaminants to said first water bath.
