Abstract
In producing sago flour takes 20,000 liters of water per ton of starch, where 94% of the water
would be liquid waste, so about 19,000 liters of wastewater generated sago starch per ton
When directly discharged into the water on a continuous basis it could lead to pollution of the
waters. The way of handling the problem of wastewater treatment can be done by using a
hybrid anaerobic bioreactor mediated stones. One of the factors that influence of the
anaerobic process success is pH and alkalinity. The purpose of this research to determine the
effect of feed flow rate on pH and alkalinity in anaerobic hybrid bioreactor at steady state by
looking at the pH and alkalinity parameters and determine the optimum conditions for
anaerobic processes. Process variables measured were feed flow rate of 2.5 L / day, 3.3 L /
day, 5 L / day, and 10 L / day operating conditions at room temperature and the bioreactor
working volume 10 L. The results showed that the optimum feed flow rate obtained on 2.5 L /
day with an average pH of 6.8 and alkalinity of 2280 mg / L.
