Vermifiltration Of Palm Oil Mill Effluent

The performance of vermifiltration (VF) systems using the Lumbricus rubellus and Eudrillus eugeniae earthworm in treating palm oil mill effluents (POME) was studied. In this work, POME is an organic wastewater generated from the production of crude palm oil that is high in COD, BOD, TSS concentratio...

In this work, POME is an organic wastewater generated from the production of crude palm oil that is high in COD, BOD, TSS concentration, low in pH, oily and has unpleasant odor and is difficult to treat and to comply with the environmental standard. POME was treated through this system, after which the changes in pH, COD and TSS were recorded.

This study has showed that the presence of earthworms could aid in increasing the removal efficiency of TSS and COD. TSS reduction in vermifilter was 95% which is higher than control filter, 87%.
