Special Issue Description

The Clean Air Act Amendments’ stricter restrictions on volatile organic compound (VOC) emissions have prompted an analysis of alternative VOC remediation strategies. Biofiltration and suspended growth reactors are two relevant technologies for gas phase treatment. Through the use of a bed of biologically active particles, biofiltration purges pollutants from gas streams. An aerobic suspended-growth reactor (SGR) eliminates VOCs by biologically processing contaminated air that is bubbled through an aqueous solution of active microorganisms. For the removal of a standard VOC (toluene) from gas streams, this study compared the effectiveness of a normal compost biofilter to an SGR. Evaluating how mass loading affected process efficiency was the goal. Major performance factors were (1) mass emitted and elimination capacity, (2) off-gas concentrations exiting each kind of reactor for varying mass loadings, and (3) removal efficiencies attained by each type of reactor. According to the findings, SGRs can efficiently detoxify gases that contain VOCs. The biofilters and SGRs both produced VOC removal rates between 96 and 99.7% for mass loadings between 5 and 30 mg/l-h. At high mass loadings, the biofilter media dried. Process performance in the SGRs was affected by the presence of an unidentified colored compound at mass loadings higher than 17 mg/l-h.
