ONCLUSION
The optimum condition of Thai MFC operation
of the POME treatment was illustrated when fed
neutral culture into the reactor at 30 g COD/l/day
HRT 1.04 day and aerated at 100 ml/min. The
maximum COD removal was 26.60 gCOD/l/day
higher than the exist wastewater treatment
technologies over 3-25 times. It is possible to scale
up to an economic scale.
