Pengaruh Variasi Laju Upflow Terhadap Pembentukan Biogas Pada Pengolahan Limb…

ABSTRACT The chemical oxygen demand (COD) in palm oil mill effluent (POME) is high 32000 mg/L allows suitable processing is anaerobic digestion because not only control pollution but also provides valuable resources in the form of biogas. This research aims to study the effect of upflow velocity variations to biogas production, dissolved COD, bacterial growth through volatile suspended sol…
