Recycle-ratio effect studies were carried out at the average loading rate of 15.6 g COD/l/d with the recycle rate varied from 5 to 25 times of the fresh-feed rate. The study shows that in the current system, a recycle of more than 15 times is needed to maintain the system pH higher than 6,8 without alkalinity supplementation, and the imposition of recycle is an effective means to reduce alkalinity requirements. Moreover, the kinetic model for substrate utilization and methane production proposed by Bathakur et al. (1991) was able to show the domination of certain culture in anaerobic processes. The model was also found to predict the experimental data of the present study with good accuracy.In this study, the effects of recycle on anaerobic baffled reactor performances in treating palm oil mill effluents were investigated and biokinetic parameters were also determined.
