Support biologies in waste water technology. The numerous possibilities of immobilizing biomass and using it fixed on a wide range of carriers in the available types of reactors is matched by a great variety of practical applications in waste water purification technology for partial, complete, subsequent, and ultrapurification. All support biologies share the following advantages to a greater or lesser extent: smaller reactor volumes and shorter reaction times thanks to higher biomass concentrations; volume reduction or elimination of subsequent purification pools owing to the more favourable sludge index and fixation in the reactor or the filter; long sludge lifetimes are possible (favourable for slowly multiplying nitrifiers and specialist strains); no floating sludge formation on carbohydrate degradation or nitrification; increase in process stability and degradation activity towards refractory compounds which are difficult to degrade biologically if suitable supports showing synergistic activity are used, such as highly porous activated charcoal.
