ABSTRACT
The anaerobic digestions, using porous ceramic supports, of dairy and carrot juice wastewaters were investigated. The ceramic supports were prepared and used for microorganism-immobilizing supports. The dairy and the carrot juice wastewaters continuously flowed into the lower part of the bioreactor, in which the porous ceramic supports were packed. The influent COD concentration and the HRT were 800—5000 mg/ / and ll>~48hrs, respectively. The COD removal rates were above 90% for both types of wastewaters. Furthermore, the acclimation time needed was shorter for the bioreactor with packed supports. From these results, it was convinced that the ceramic supports could be applied to the treatment of highly concentrated wastewater.
