Abstract:

The anaerobic attached film expanded bed process AAFEB has been shown to be capable of treating low strength waste-waters at low temperatures and at relatively short retention times. Such capability leads to the unexpected conclusion that the AAFEB is a municipal wastewater treatment alternative capable of meeting secondary effluent quality without producing a secondary waste sludge. In order to understand reasons for this extraordinary capability, recent research has focused on reproducing the phenomena, evaluating the kinetics with soluble and insoluble substrate at varying temperatures, testing of the system under shock loads, and evaluation of the potential applications algae harvested or operation under thermophilic temperatures, 50 C. This paper will relate the research data to process fundamentals active biomass, solids retention time, substrate kinetics and design requirements.
