The mathematical model of the biofilteration of dimethyl sulphide (DMS) in a benchscale biofilter is presented. This model contains the diffusion of the compounds through the c and degradation of the compound along the biofilter column. The model presented here is based on the mass transfer in gas-biofilm interface and chemical oxidation in the gas phase. Analytical expressions pertaining to the dimethyl sulphide concentration in the gas phase and bio-film phase have been derived using the new Homotopy perturbation method for all possible values of parameters. Furthermore, in this paper the numerical simulation of the problem is also reported using the Matlab program to investigate the dynamics of the system. A satisfactory agreement between theoretical predictions and numerical result is observed.
