jOm Dynamic Modeling and Experimental Investigation of Ammonia Removal from Air by a Biofilter s mohammadian@ce iut ac ir submitted 15 Mar 2010 Department of Chemical Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Prof Arjomand Mehrabani arjmand@cc iut ac irAbstractBiofilteration technology for the removal of pollutants from air streams is unregarded in our country Thismethod is applied to polluted air streams with high flowrate and low concentration of pollution andeconomic in comparision with other methdos such as catalytic oxidation or gas absorption This method isnot only simple but also it is a low energy consumption method without secondary polllutants In thepresent reaserch a bench scale biofilter for removal of ammonia from air was designed and constructed During 4 months continuos operation of the biofilter its performance was evaluated under various inletpollutant concentrations and polluted air flowrates as effective operational parameters Results have shownthat biofilter removal efficiency is affected by various prameters such as temperature water content of bed and input pulses The biofilter minimum maximum and average of efficiency under steady state conditionswere 99 8 91 4 and 97 5 respectively In addition the complete removal capacity and the maximumremoval capacity of the biofilter were 6 and 11 6 g NH3 m3 bed volume h respectively Mass transfercoefficient of the biofilter and the maximum biodegradation rate of the microbial culture were determinedat 0 24 h 1 and 3 7 g NH3 m3 bed volume min based on regression of the experimental The presentedmodel predicts the experimental data accordingly and its maximum difference with the reportedexperimental results of Taghipour et al and Chen et al are 9 4 and 3 6 respectively Keyword Biofilter Ammonia Dynamic modeling Complete removal capacity Maximum removal capacity
