Abstract
With the sludge treatment, the solubilization process of sewage sludge invites our attention because of the shortage of a final disposal site. In this chapter, a high-speed rotary disk process was applied to solubilization of sewage sludge from a sewage plant. With anaerobic treatment, the solubilized sludge by high-speed rotary disk process could be shortened from a digestion period of 30 to 10 days. Moreover, by applying the solubilized sludge to the activated sludge process, the excess sludge produced from the final sedimentation tank could be reduced to approximately 60%.
