Abstract
The conventional treatment method for palm oil mill effluents (POME) is predominantly
anaerobic system, which involves the use of various bioreactors. Some of these bioreactors
have been studied for the treatment of POME at laboratory scale, though few have been
applied industrially. Such bioreactors include up-flow anaerobic sludge blanket (UASB)
reactor, up-flow anaerobic filtration, fluidized bed reactor, up-flow anaerobic sludge fixed-film
(UASFF) reactor, anaerobic contact digester, continuous stirred tank reactor (CSTR) and
membrane bioreactors. Few studies on the application of bioreactors based aerobic activated
sludge reactor and evaporation method have been reported. Chemical oxygen demand (COD)
is the parameter that measures the level of pollutants in wastewater, thus, this mini-review
compares the various bioreactors, employ in the treatment of POME, based on their chemical
oxygen demand (COD) removal efficiencies and thus envisages feasibility of introducing
novel bioreactor for effective treatment of POME.
