A novel wastewater treatment process with thermophilic aerobic sludge digestor (TAD) was developed to reduce excess sludge generated from an activated sludge (AS) process. The TAD was operated at 65°C with hydraulic retention time 1 day. The SS solubilization and VM removal in the TAD were 35% and 20%, respectively. A 40L-scale conventional AS and the new processes with appropriate volume of the TAD were operated under BOD-SS loading of 0.3kg/kg⋅d and MLSS of 2, 000mg/l using artificial wastewater over 100 days. As a result, the amount of excess sludge was 4.9gSS/d in the conventional AS process. On the other hand, excess sludge in the new process was reduced to nearly zero when the amount of excess sludge to be solubilized was three times larger than the expected excess sludge in the conventional AS process. Effluent BOD was the same level in the both processes, however, effluent S-TOC was 25% higher in the new process than that of the conventional AS process. The calculated operating cost of the new process was about one third or one half compared to dewatering and landfill processes.

PABIO MOVER, a fluidized bed aerobic biofilm treatment process, has many advantages such as high -loading operation, no backwash requirement, flexible reactor design. A demonstration test with a bench scale unit using artificial wastewater confirmed the mechanism of the high-rate treatment: increased oxygen transfer rate by moving carrier elements of special shape, high removal ratio of organic substances with microorganisms, and microbial habitat segragation. Pilot tests using wastewater from brewery and food processing plants achieved removal ratios from 99 to 95% at 4 to 6 kg/m
3/d BOD volumetric loading. A commercial unit of the PABIO MOVER is operating successfully at a food processing plant.
