Anaerobic Fluidized Bed (AFB) Process

Anaerobic Fluidized Bed (AFB) Process
Introduction

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.

More Information

Applications
Various types of wastewater have been treated successfully by AFB process, including wastewater from the food processing, fermentation process, paper mill, chemical manufacturing, resin manufacturing, etc.

Features

  • Able to retain a high concentration of biomass with high specific activity and handle a high volumetric loading with efficient COD removal.
  • Particularly applicable to wastewater of lower concentration and to wastewater containing biological inhibitive compounds under the high hydraulic loading operation.
  • Reactor is often tall, less footprint is needed.
