The BFBR - Buoyant Filter Bioreactor
The buoyant filter bioreactor - BFBR –
(US Patent 6,592,751), is a unique solution to
the high rate anaerobic treatment of complex
wastewaters. Anaerobic sludge, is retained in the
reactor by a special low density granular filter
system integrally provided in the reactor. Thus
the separation of sludge and its retention in the
reactor is independent of the settleability of
sludge. The reactor contents i.e., complex waste
and microbial biomass are in well-mixed
condition, using either proven gas sparging
methods or optional mechanical agitators.
