Gas-induced fluidized-bed reactors are suited for permanent anaerobic digestion without runbacks. The carrier particles must have a high fixing capacity and mechanical stability for permanent-biofilm formation.  The suitability of macroporous polyurethane carrier materials, the biofilm formation properties, the digestion of substrates and the production of biogas were investigated for synthetic waste water and potato starch waste water in 70 l liquid upward current reactors, bubble column reactors and gas lift loop reactors with/out gas recirculation.
