Performance of an Anaerobic Stage Reactor (ASR) Treating Synthetic Wastewater during Start-Up Phase Using Palm Oil Mill Effluent (POME) Sludge

摘要

ABSTRACT Start-up of an anaerobic reactor depend on various factors, such as wastewater composition, organic loading rate (OLR), hydraulic retention time (HRT), seed sludge, temperature, and reactor configuration. Accordingly, the present study describes results of an investigation into start-up performance of an anaerobic stage reactor (ASR) using palm oil mill effluent (POME) sludge. The average chemical oxygen demand (COD) removal efficiency of the reactor system was 55% when the ASR was ope.
