Model Study Based on Experiments on Toluene Vapor Removal in a Biofilter
Publication: Journal of Environmental Engineering
Volume 130, Issue 10
Abstract
A study on the prediction of toluene vapor removal in a biofilter using an acclimated mixed-culture was carried out on the basis of experimental data obtained under various states of inlet vapor concentrations, flow rates or empty bed retention time, and biofilter temperature. Variations of removal performance and parameters with biofilter temperature and vapor organic load were examined. Several kinetic models such as a first-order reaction equation and mathematical models of Ottengraf, Ottengraf-van den Oever, van Lith et al., and Kornegay-Andrews were applied and examined with respect to the prediction performance of toluene vapor removal under pseudo-steady-state conditions. Limitations of the models were investigated, and optimal operating conditions and various design parameters such as degradation rate constant, maximum elimination capacity, and removal efficiency were also determined.
