Abstract

The simultaneous aerobic removal of a mixture of BTEX (benzene, toluene, ethyl benzene, o,m,p-xylene), cis-dichloroethylene (cis-DCE) and trichloroethylene (TCE) from the artificially contaminated water using an indigenous bacterial isolate identified as Pseudomonas plecoglossicida immobilized on waste scrap tires was investigated. Suspended and immobilized conditions were compared for the enhanced removal of these volatile organic compounds. For the immobilized system, toluene, benzene and ethylbenzene were completely removed while the highest removal efficiencies of 99.0±0.1%, 96.8±0.3%, 73.6±2.5%, and 61.6±0.9% were obtained for o-xylene,m,p-xylene, TCE and cis-DCE respectively. The sorption kinetics of contaminants toward tire surface was also evaluated and the sorption capacity generally followed the order of toluene> benzene> m,p-xylene> o-xylene> ethylbenzene> TCE> cis- DCE. Scrap tires showed a good capability for the simultaneous sorption and bioremoval of BTEX/cis-DCE/TCE mixture implying a promising waste material for the removal of contaminants mixture from industrial wastewater or contaminated groundwater
