This experiment was carried out to investigate biomass concentrations of attached biofilm in a Fluidized-Bed Biofilm Reactor(FBBR) which was run by varying influent COD from 2.070mg/l to 12,400mg/l. The following conditions fixed during the experiments; superficial upflow velocity was 0.47cm/s, operating temperature was 22±1℃ and pH was 7±0.1. The Substrate was glucose based synthetic wastewater. The COD removal efficiency was shown as 73% and 93%, respectively, when influent COD was increased from 2.070mg/l to 12,400mg/l. The observed biomass concentrations were pretty close to those calculated from the equation with measured parameters, such as biofilm thickness, biofilm density, bed porosity and bioparticle diameter.
