Abstract
The performance of anaerobic processes in the bioconversion of palm oil mill effluent into
gaseous fuel is ve/y dependent on the concentration of biomass. Effort to increase the
concentration of anaerobic biomass can be done by using anaerobic hybrid bioreactor. The
bioreactor used had 3 chambers, each divided for an up and down flow pattem and having a
working volume of 2,5 rrr. This study uses two anaerobic hybrid bioreactors equipped with cell
immobilization media. Media used in cell immobilization is a medium density form of solid palm
oil mills waste, namely: empty fmit bunch and palm midrib. Both bioreactors tested their
performance by increasing feed flow rate unexpectedly by 50%, 100% and 150% under room
temperature conditions and continuous operation. The results showed that the anaerobic hybrid
bioreactor system was capable of converting single-phase oil palm mill effluent with a good
performance, and testing with the feed Dow rate increased abruptly by 50%, 100%, and 150%
indicates that the recovery time of the anaerobic hybrid bioreactor system is Single-phase of
media empty fruit bunches <fnd palm midrib of media held fast with a periode of 6 to 8 days.
Thus, the suddenly increase rate of the feed does not affect the performance of a single-phase
anaerobic hybrid bioreactor, and the stability of the bioreactor is relatively high so as to convert
liquid waste into fuel gas
