“…In Malaysia, about 85% of POME treatment system is based on conventional biological treatment methods of acidification, anaerobic, facultative and aerobic digestion [4,18]. The anaerobic digestion process is a suitable treatment method for rapid disintegration of organic matter to produce biogas that can be utilized for electricity and as energy source [19,20].…”

The expanding of oil palm industry has given a significant benefit to the economic growth and country development. However, it has also contributed to environmental problems due to the production of huge quantities of waste and byproducts. Palm oil mill effluent (POME) is a liquid discharge from the palm oil milling process. POME without proper treatment could be harmful to environment because it emitted greenhouse gas emissions into the atmosphere. Therefore, due to its high organic carbon content, POME has currently been applied to generate biogas. This study aims to measure the physicochemical characteristics of untreated POME and the potential of POME as renewable energy. The physicochemical characteristics of raw POME such as chemical oxygen demand (COD), ammonia (NH3N), dry matter (DM) content and heavy metals were also measured and compared with the regulatory discharge limits. Converting POME to biogas can produce energy which save a huge source of renewable energy as well as reduce the environmental impacts of palm oil production.Cite this article as: Nur Izzah Hamna A.

“…Some commonly encountered problems in the operation of EGSB include scum formation, sludge floatation, and pipeline blockages. To resolve these drawbacks, pre-treatment step is normally required to remove large particles, suspended solids, oil, and grease prior to feeding into EGSB reactor (Zhang et al 2008). …”

“…However, the production of palm oil leads to the increasing amount of polluted effl uent namely palm oil mill effl uent (POME) that possesses extremely high biological and chemical oxygen demands (BOD and COD) that cause great threat to the quality of water environment nearby (Zhang et al 2008a). 44 million tons of POME was generated during the year of 2008 and if discharged untreated, this would then make the palm oil mill industry in Malaysia an industry which generates the biggest pollution load into the drainages (Wu et al 2010).…”

Abstract:In this work, response surface optimization strategy was employed to enhance the biodegradation process of fresh palm oil mill effl uent (POME) by Aspergillus niger and Trichoderma virens. A central composite design (CCD) combined with response surface methodology (RSM) were employed to study the effects of three independent variables: inoculum size (%), agitation rate (rpm) and temperature (°C) on the biodegradation processes and production of biosolids enriched with fungal biomass protein. The results achieved using A. niger were compared to those obtained using T. virens. The optimal conditions for the biodegradation processes in terms of total suspended solids (TSS), turbidity, chemical oxygen demand (COD), specifi c resistance to fi ltration (SRF) and production of biosolids enriched with fungal biomass protein in fresh POME treated with A. niger and T. virens have been predicted by multiple response optimization and verifi ed experimentally at 19% (v/v) inoculum size, 100 rpm, 30.2°C and 5% (v/v) inoculum size, 100 rpm, 33.3°C respectively. As disclosed by ANOVA and response surface plots, the effects of inoculum size and agitation rate on fresh POME treatment process by both fungal strains were signifi cant.
