摘要: An Upflow Anaerobic Fixed Bed (UAFB) reactor packed with activated carbon was used to remove the azo dye Reactive red 272. The biomass grown on surface composed of an adapted consortium microorganisms. Residence time distribution test indicated that a plug flow behavior. A dynamic mathematical model is presented for flux along and within bioparticles two regions: core biofilm. considers reaction performed in biofilm liquid phase includes transport by dispersion diffusion. concentration profile changes height as equilibrium achieved. Changes concentrations affect reduce removal efficiency. effectiveness factor depends at inlet.
