1 Performance and kinetics of a fluidized bed anaerobic reactor treating distillery effluent
-
Seth Apollo
Abstract
The kinetic analysis of an anaerobic fluidized bed bioreactor treating distillery effluent was carried out. Natural zeolite was used as biomass carrier at various organic loading rates and hydraulic retention times (HRT). The degradation followed first order kinetics and fitted Michaelis-Menten kinetic model for substrate utilization. The kinetic analysis showed that 9% of the TOC was nonbiodegradable which corresponds to about 14% COD. The non-biodegradable component was responsible for the dark-brown color of the distillery effluent and therefore there was a need for employing a post-treatment technology for their removal. Biomass yield was found to be 0.4658 g/g while endogenic microorganisms decay coefficient was 0.0293, which suggested that there was a need to install a sludge handling unit prior to posttreatment. The maximum micro-organisms’ growth rate was found to be 0.136 d−1 while the specific growth rate of the micro-organisms reduced with an increase in HRT at constant feed concentration. The specific substrate utilization rate was found to increase linearly with an increase in the ration of food to micro-organisms and the mean cell residence time was found to be at least 2.5 times the HRT due to application of zeolite as microbial support in the reactor.
