dc.description.abstractThe continuous anaerobic degradation of an acidic waste water from a cellulose process was investigated in six fluidized bed reactors. Various materials including limestone, porous glass, quartz sand, activated carbon and treated coal were used as support particles. The reactors were operated for several months with vapour condensate from a sulphite cellulose process as feed. The performance and stability of the reactors with respect to degradation rate were tested for a range of loading conditions. Unbuffered, buffered and pH-controlled conditions were compared. The results showed that the high-density, small-sized sand was the best carrier. Carrier porosity was not important, although surface roughness appeared to be important. No clear evidence of diffusional influence on the kinetics was observed. The highest rates and best stability was obtained with the sand carrier which had the thinnest biofilm; these rates were 21 kg COD/m3. d(unbuffered feed), or 25 kg COD/m3. d (buffered feed and pH-controlled system). The sand system was relatively stable with respect to pH changes. With pH control, loading could be increased until a maximum reaction rate, as determined by the saturation kinetics, was achieved.de_CH
