Modi University, Newai (Rajasthan), India Rahul Dr. 2 Chemical Engineering Department, Lakshmi Narain College of Technology, Bhopal (M.P.), India > Research Paper 2017 6 14 2017 08 18 The complete performance of a corn cob biofilter inoculated with microbial culture was optimized for the treatment of polluted air containing gas phase of MTBX. The biofilter was operated for the period of 149 days and this time period was divided into five phases (I-V) to differentiate between the outputs of biofilter. On the removal efficiency (RE) and elimination capacity (EC), the effects of various parameters like gaseous concentration and flow rate were investigated. The removal efficiency was measured with respect to inlet concentration of each component of MTBX and the elimination capacity was varied with change in loading rate of gaseous mixture. The maximum RE in MTBX was of n-butyle acetate (BA) with 99.98% with respect to inlet concentration of 0.118992 gm-3 while the minimum RE was of o-xylene with 98.21% for the concentration of .0.189568 gm-3. In case of EC the maximum value was obtained as 86.27 g m-3 h-1 for n-butyle acetate at the highest value of inlet load of 114.69 g -3 h-1. By performing an analysis of variance the results were statistically interpreted to elucidate the main and interaction effects. Copyright@ International Science Community Association
