Abstract:
Industrial development was followed by an increase of sago starch sago wastewater
generated. In producing sago starch takes 20,000 liters of water per ton of starch, which is
94% water would be liquid waste sago. Sago effluent has COD (Chemical Oxygen Demand)
to 100,000 mg / l. These conditions will have a negative impact on the environment if not
managed properly. One way to lower the COD content by using hybrid anaerobic bioreactor.
Conditions Start up is one of the important conditions in wastewater using hybrid anaerobic
bioreactor, because this happens to reach the steady proliferation of microorganisms. This
study aims to review the condition of the start-up of hybrid anaerobic bioreactor COD
parameter and observing the resulting biogas. The research was carried out with a flow rate
of 2 l / day at room temperature. The results showed that the COD removal efficiency of the
largest obtained 90,45% with pH 6.2 as well as the operation of the biogas production of 14
982 ml / day. The results of this study indicate that the start-up of hybrid anaerobic
bioreactor lasts for 59 days.
