Impact of the amount of moving bed in the continuous flow bioreactor on the required bioreactor volume has been investigated with respect to conventional activated sludge bioreactors preceded with primary sedimentation or chemical precipitation. The investigation has been carried out for a fictitious plant of the size of 1999 people equivalent (PE). It was found that for the systems designed for removal of organic matter: the volume of the integrated fixed film activated sludge (IFAS) reactor with the 15% filling ratio is similar to the volume of the activated sludge reactor (ASR) preceded with primary settlement tanks operating at 2.0 h hydraulic retention time (HRT). The volume of the IFAS reactor with the 30% filling ratio is comparable with the volume of the ASR reactor preceded with an upstream chemical precipitation stage assumed to achieve 60% removal of organics.
