| Summary: | Palm oil mill effluent (POME) is a high strength organic wastewater, which adversely affects aquatic life
as well as human life directly or indirectly. This has attracted concern due to the rapid expansion of the
oil palm industries in countries such as Malaysia and Indonesia, which currently contribute about 80%
of the world palm oil. The conventional bioreactors such as pond digester, anaerobic filtration, up-flow
anaerobic sludge blanket (UASB), up-flow anaerobic sludge fixed-film (UASFF), continuous stirred tank
reactor (CSTR), anaerobic contact digestion and fluidized bed, used over the past decades are largely
operated anaerobically. They have been reported to be less effective for the treatment of the increasing
volume of POME as well as meeting the new stringent wastewater treatment standards. Therefore,
treatment method such as aerobic under a continuous system is anticipated to be effective alternative
to the defects observed in the previously employed bioreactors. The use of semifluidized bed
bioreactor containing immobilized cells for the biodegradation of various high strength organic
wastewater have been reported as highly efficient treatment method. Thus, to address the increasing
environmental impact of POME in the producing nations, the application of semifluidized bed bioreactor
as a novel technology in the palm oil industry will be of immense benefit, economically and
environmentally. |
