KARAKTERISTIK PENGOLAHAN LIMBAH CAIR PABRIK MINYAK KELAPA SAWIT DALAM BIOREAKTOR CIGAR SEMI KONTINU
ABSTRACT: Palm oil mill
effluent (POME) waste water contains high consentration of organic pollutants.
Anaerobic treatment is suitable to reduce the pollutans and also produce
methane as one of renewable energy sources. Anaerobic degradation is
complicated and sensitive process to the environtment, such as temperature and
organic consentration. This study aims to determine characteristic of palm oil
mill waste water treatment using semicontinue anaerobic CIGAR bioreactor. The
seed was collected from sludge of anaerobic pond at POME treatment facility of PTPN
VII Bekri. The substrat used in this experiment was fresh POME from the same
mill. Initially, 4,375m 3 of sludge was introduced into the bioreactor. The
seed was acclimatized at a loading rate of 50 l/day for about a week. Anaerobic
treatment was conducted at room temperature and the substrat was fed
semicontinuelly at a loading rate of 100 to 350 liter/day. Results showed, that
the stability of anaerobic degradation was achieved at an organic loading rate
(OLR) of 0,9-3,11 kg/m3/day with COD removal more than 90% and maximum biogas production
of 2,59 m3/day.
