Abstract: Bio-ceramic filter is one of the most widely used surface water treatment units in China. However, there is no simple and practical model to guide engineering design or aid the investigation of feasibility. According to the inner characteristics of fluid motion of bio-ceramic filter, plug-flow reactor model was applied to simulate organic removal of surface water. Moreover, the model was verified using the experimental data, based on the treatment of two surface waters with greatly different degree of organic pollution using pilot-scale bio-ceramic filter. The result indicates that plug-flow reactor model with first-order reaction could ideally simulate the CODMn removal using bio-ceramic filter.
