Biological aerated filters are wastewater-treatment systems which contain support media for the develop ment of a biofilm and provide oxygen at the base of the reactor for aerobic microbial processes. The origins of this type of filter date back to the early 1900s, and modem designs can provide a high level of treatment in small reactor ‘footprints’. This paper provides a review of the technology and development of biological aerated filters and submerged aerated filter systems.
