Comparison of biological H₂S removal characteristics between a composite packing material with and without functional microorganisms.

ABSTRACT: The performances of two identical biofilters, filled with a new composite packing material (named CM-5) embedded with functional microorganisms or sterilized CM-5 without microorganisms, were investigated for H₂S treatment. Running parameters in terms of microbial counts, pressure drops, and inlet and outlet H₂S concentrations were measured. The results show that the microbial count of the CM-5 was approximately ×10⁵ CFU/g before being filled into the biofilter, while that of the sterilized CM-5 was negligible. The functional microorganisms embedded in CM-5 adapted to the environment containing H₂S quickly. In most cases, pressure drops of the CM-5 biofilter were slightly higher than those of the sterilized CM-5 biofilter when the gas flow rate w
