Production of Biogas from Palm Oil Mill Effluent at Pilot Scale: Effect of Recycle Sludge
An anaerobic digestion of palm oil mill effluent (POME) for production of biogas was carried out at pilot scale under thermophilic condition. The objective of this research is to maintain short hydraulic retention time (HRT) and high degradation of the POME to biogas by applying recycle sludge. Fresh POME from PTPN IV without further treatment was used as feed. The fermentation process occurred...
متن کاملElectrocoagulation of Palm Oil Mill Effluent
Electrocoagulation (EC) is an electrochemical technique which has been employed in the treatment of various kinds of wastewater. In this work the potential use of EC for the treatment of palm oil mill effluent (POME) was investigated. In a laboratory scale, POME from a factory site in Chumporn Province (Thailand) was subjected to EC using aluminum as electrodes and sodium chloride as supporting...
متن کاملRespirometric analysis of activated sludge models from palm oil mill effluent.
Activated sludge models (ASMs) have been widely used as a basis for further model development in wastewater treatment processes. Values for parameters to be used are vital for the accuracy of the modeling approach. A continuous stirred tank reactor (CSTR), as open respirometer with continuous flow for 20 h is used in ASMs. The dissolved oxygen (DO) profile for 11 days was monitored. It was foun...
متن کاملAccelerated Start-up of a Semi-commercial Digester Tank Treating Palm Oil Mill Effluent with Sludge Seeding for Methane Production
The modern closed digesters are becoming more popular for treating palm oil mill effluent (POME) and are currently being installed nationwide in Malaysia to replace the conventional open lagoons and tanks treatment system. This paper describes an accelerated start-up of the 500 m semi-commercial anaerobic digester 3 treating POME and methane gas recovery for clean development mechanism (CDM) pr...
متن کاملReactivation of Preserved Aerobic Granular Sludge Using Palm Oil Mill Effluent
Generation of wastes in the form of palm oil mill effluent (POME) is unavoidable due to increase in oil palm development worldwide. Direct discharge of POME into receiving water bodies is strongly discouraged due to high chemical and biochemical oxygen demand concentrations, respectively. Aerobic granulation technology features microbial aggregates generated following immobilization and cell-to...
