Anaerobic fluidized bed (AFB) is an anaerobic wastewater treatment method. Inert carriers providing large surface area for attachment and growth of anaerobic microorganisms are added in the AFB bioreactor. The biofilm attached carriers are fluidized through upflow water to enhance mass transfer and degradation of organic pollutants.
