With the increasing deterioration of world water resources,
configuring a technical and economic viable wastewater
treatment and recycle technology to satisfying the
increasing complexity of wastewater and stringent
environmental regulation has been a great challenge over the
past decades. Developing reliable technologies for
wastewater treatment is of urgent importance. In recent
years, anaerobic baffled reactor (ABR) treating wastewaters
effectively, have received considerable attention in the
literature. This paper reviews the development and
application, performance and characteristics, modeling of
the ABR for wastewater treatment and the combination of ABR
with other processes during the last decade. This paper
provides a critical review on the ABR for treatment of
refractory wastewaters. It was indicated that ABR had become
a promising alternative for wastewaters treatment with great
further development potential.
