Numerical Solution and Sensitivity Analysis of Phenol Biodegradation

In this study a mathematical model consisting of mass balance equation and accounting for reaction, mass transfer is developed to describe unsteady state phenol degradation in biofilter. For simulation purpose software BIOPHEN was developed in the language ForTran 77 and subsequently solved using Backward Implicit Scheme. The removal efficiency of phenol at inlet concentration is 99.47%. First order reaction kinetics is used .The concentration at different height and different time is obtained,which is not only useful for the design but is also applicable for predicting the concentration at various location and time of the bioreactor.The effect of parameter Specific surface area, biofilm thickness , and porosity on the performance of the biofilter were also investigated.
