In
sewage treatment systems, an
anaerobic filter (
AF) is a form of anaerobic digester. The digestion tank contains a filter medium where anaerobic microbial populations—organisms that live in the absence of oxygen — can establish themselves. Such filters are commonly employed in the treatment of
waste water. These reactors are gaining in popularity versus more established aerobic waste-water treatment systems because they produce a less solid residue
than do other types of filter.
