Abstract

Phenol is one of the recalcitrant chemical present in the environment which needs lot of attention for treatment processes The feasibility and performance of three phase Inverse Fluidized Bed Biofilm Reactor IFBBR was investigated for the biodegradation of synthetic phenolic effluent of various concentration 400 600 800 1000 and 1200 mg L using low density polystyrene support particles newlinePseudomonas fluorescens was used as the model organism for the degradation process in IFBBR Biofilm and biomass characteristics of P fluorescens were determined by evaluating biofilm dry density and thickness bioparticle density suspended and attached biomass concentration chemical oxygen demand and phenol removal efficiency Biodegradation kinetics was studied for the suspended biomass culture and biofilm system The experimental data was fitted with the kinetic models of Monod Haldane Aiba et al Teissier Webb and Yano Koga The model with best fit was selected on the basis of highest correlation coefficient R2 and the least Root Mean Square Error RMSE values Suspended biomass followed substrate inhibition kinetics and the experimental data fitted well with the Haldane model newline newline%%%reference p144-158.
