Abstract
Three new biosolids treatment processes are introduced: vertical shaft digestion (VSD), vertical shaft floatation (VSF) thickening, and gas-phase biofiltration. The combination of these three major processes, and a few supplemental units (such as grit removal, dewatering and drying) provide complete biosolids treatment. The topics covered in this chapter include: biosolids treatment objectives, vertical shaft bioreactor, vertical shaft flotation, vertical shaft digestion, aerobic digestion, autothermal thermophillic aerobic digestion, anaerobic digestion, dewatering, air emission control by biofiltration, engineering design, and case histories.
