Abstract

The purpose of this study is to compare the performance of rubble support media coated perlite and non-coated media. As rubble was coated perlite, the porocity of reactor was increased 5.6%, whereas packing weight was decreased 17.6%. When rubble was coated perlite, microorganisms were attached on the surface of support media after 2 hours. TCOD removal efficiency of the reactor packed with rubble support media coated perlite was higher 4~9% than that of rubble. The end of experiment, MLVSS of rubble support media and rubble coated perlite was 1858.8mg/ι, 2785.9mg/ι, respectively.
