In this paper, the non linear boundary value problem in a biotrickling filter system using Chelatococcus daeguensis under thermophilic condition is discussed. The approximate analytical expression of NO concentration in the gas phase can be obtained using Homotopy perturbation method (HPM) for various values of relevant parameters. We also compared our analytical results with the available numerical results and are found to be in good agreement.
