Abstract
Anaerobic pretreatment and aerobic post-treatment of municipal wastewater is being used more frequently. Recent investigations in this field using an AFBR/aeration chamber combination demonstrated the technical feasibility of this process. The investigation presented herein describes the use of a combined UASB/aeration chamber system for the treatment of municipal wastewater and attempts to demonstrate the technical feasibility of using the UASB process as both a pretreatment unit and a waste activated sludge digestion system. The results indicate that the UASB reactor has a TSS removal efficiency of about 37%. Of the solids removed by the unit, 33% were degraded by the action of microorganisms, and 4.6% were accumulated in the reactor. The results also show that accumulation of solids in the UASB reactor took place in the upper zone of the sludge bed.
