| Abstract: | This
study presents treatment performance of cafeteria waste and polyhydroxyalkanoate
(PHA) production in two stage process through an up-flow anaerobic sludge bed
(UASB) and sequencing batch reactor (SBR). COD removal efficiency was found as
follows: SBR, 93; and UASB - SBR, 95.4%. In addition, 30% ammoniacal nitrogen
(AN) was noted at high aerobic condition and phosphate (PO4) removal efficiency
increased at high anoxic conditions. Volatile fatty acid (VFA) intermediates such
as acetic acid increased from 505 up to 4315 mg.l-1 in effluent of
UASB reactor and successfully consumed in SBR for PHA production. Acetic acid
concentration was reduced significantly in SBR from 4315 to 50 mg.l-1.
During this period, PHA production was increased to 68% over cell dried weight,
confirming effectiveness of sequential UASB-SBR system in producing bioplastic
from cafeteria waste. |
