Effect Of The Organic Loading Rate On The Performance Of Mesophilic And Thermophilic Anaerobic Digestion Of Palm Oil Mill Effluent
This project investigates the performance of mesophilic and thermophilic anaerobic digestion of palm oil mill effluent (POME). First, the scum-sludge mixture was acclimatized at mesophilic and thermophilic temperature prior the start-up of anaerobic digestion. The rapid CH4 production under both tem...
