Technology Assessment of Anaerobic Systems for Municipal Wastewater Treatment: 1. Anaerobic Fluidized Bed. 2. ANFLOW

摘要

This report discusses two developing technologies for the treatment of municipal wastewaters. These technologies are anaerobic fluidized bed systems and an anaerobic fixed-film bioreactor (ANFLOW). The report discusses: available laboratory data on system performance; fluidized bed expansion and voidage-velocity relationships; the influence of bacterial growth on changes in fluidization characteristics; power requirements for fluidization; potential cost and energy savings compared to activated sludge secondary treatment plants; and provides estimates of anaerobic fluidized bed treatment costs.
