Biomethanation Of Palm Oil Mill Effluent (POME) By Ultrasonic-Membrane Anaerobic System (UMAS)
Palm Oil Mill Effluent (POME) is the wastewater produced during the production of palm oil. POME is a brownish, colloidal suspension that can cause severe damage to environment because of its high chemical oxygen demand (COD) and biochem ical oxygen demand (BOD). POME often released...

| Summary: | Palm Oil Mill Effluent (POME) is the wastewater produced during the production of
palm oil. POME is a brownish, colloidal suspension that can cause severe damage to
environment because of its high chemical oxygen demand (COD) and biochem
ical
oxygen demand (BOD). POME often released at high temperature (70
-
80°C) and has
pH values between 3.5 and 4.5. In this study, Ultrasonic
-
Membrane Anaerobic system
was used as a cost
-
effective design to treat POME while methane gas was collected
from th
e biomethanation process. POME was continuously feed into an anaerobic
reactor and pH was maintained at 1.75 bar. Temperature was maintained between 30
and 35°C. Samples from reactor and permeate were collected after 5 hours of operation
for the analysis o
f COD, BOD, total suspended solids (TSS) and volatile suspended
solids (VSS). At the end of 5 hours operation, biogas was collected from the top of 200
litres of UMAS reactor using a designated syringe. Throughout the experiment, the
COD and BOD removal ef
ficiencies were 66.06% and 96.88% respectively. 94.24% of
total suspended solids removal was achieved at 10 days of hydraulic retention time. The
methane gas production efficiency was 83.61%. The membrane fouling problem
reduced and the treatment of POME w
as improved by UMAS introduction. |
