Start-up regime of two-phase Upflow anaerobic sludge blanket reactor

Abstract

In the present study, an attempt has been made to start-up a bench scale two phase upflow anaerobic sludge blanket (UASB) reactor with sago wastewater as feed. The reactor was started with sago wastewater as feed with initial COD of 2200 mg/L. Entire process was carried out for 57 days with hydraulic retention time (HRT) of 24 h. Maximum COD removal at the start-up period in the reactor was 91.0 %. Volatile fatty acid (VFA) was under stable level for efficient operation of the reactors. The pH of feed was maintained in range of 6.2-6.8 for efficient survival of microorganisms. At maximum COD reduction the biogas production was high as 72 L/d.
