• How palm oil mill effluent affect biogas production efficiency?
  • The characteristics of Palm Oil Mill Effluent (POME) is a crucial factor affecting the yield and quality of biogas produced from anaerobic digestion. Hence, it is essential to understand how the operational processes and equipment in palm oil mills can affect POME characteristics and subsequently, biogas production efficiency.
  • What is a wet palm oil mill?
  • By understanding the role of each unit operation in the extraction process, steps can be taken to optimize efficiency and reduce negative environmental impacts. The typical processes of wet Palm Oil Mill (POM)s include sterilization of FFB, stripping, digestion, and pressing, clarification and kernel oil recovery.
  • What is palm oil mill effluent?
  • Introduction Palm Oil Mill Effluent (POME) is the thick brownish effluent typically discharged at a temperature between 80 ¡ãC and 90 ¡ãC with a pH ranging from 4 to 5.
  • Is palm oil a toxic liquid waste?
  • While POME is generally regarded as a non-toxic liquid waste since chemicals are not used during oil extraction (Saad et al., 2021), its discharge without treatment can have significant environmental consequences, particularly for rivers, due to its high organic content and the large volume produced by palm oil mills.
  • How is palm oil extracted?
  • During digestion, the fruit’s mesocarp is loosened from the nuts and directed into the mechanical press machine to extract the crude palm oil out of the mesocarp (Harsono et al., 2014). After pressing, the palm fruits are separated into two parts: press liquor and press cake.
  • How much water is used in palm oil extraction?
  • As reported by Ahmed et al. (2015), a huge amount of water is used in the crude palm oil extraction process, with approximately 1.5 m3 of water being used to process one tonne of fresh fruit bunch, and half of the water exits as wastewater, known as POME.
