In an earlier review on this subject, Sheehan and
Greenfield (1980) discussed treatment options practiced
in the 1970s. More recently, Wilkie et al. (2000) have
examined characteristics and anaerobic treatment of
effluent obtained from different feedstock used for ethanol
manufacture. This review focuses on the advances in
molasses-based distillery wastewater treatment in the
last two decades and the emerging technologies in this
field.
