In this study, granular activated carbon (GAC) was chosen as the packing material to test potential improvements to current biofiltration processes by investigating the use of a novel support medium for mixture gases removal. Carbon characteristics were investigated to study its feasibility as a packing material for biofiltration. The experimental data showed that GAC had a large surface area, porous structure, neutral pH, high adsorption capacity and uniform shape that were favorable for use as a medium of biofiltration. Immobilization tests indicated that microorganisms grew rapidly and formed a satisfactory biofilm on the carbon surface. The results of this study demonstrated that GAC with biofilm formed a novel packing medium termed in this study as biological activated carbon (BAC).
