   Sammanfattning : This thesis evaluates a novel technique to increase the active biomass inside continuously stirred tank biogas reactors with possible benefits of shorter retention times, higher degree of degradation, higher methane yield and tolerance of higher organic loading rates. The technique includes addition of magnetic biomass carriers to the process which, after adhesion of active microorganisms, can be magnetically separated at reactor outflow and reintroduced to the process.
