  • Post-treatment of palm oil mill effluent (POME) using combined persulphate with hydrogen peroxide (S2O82−/H2O2) oxidation

    The aim of the current study is to evaluate the effectiveness of combined persulphate with hydrogen peroxide (S2O82−/H2O2) oxidation as a post-treatment of biologically treated palm oil mill effluent (POME) for the first time in the literature. The removal efficiencies of chemical oxygen demand (COD), ammoniacal nitrogen (NH3-N), and suspended ...

  • Production of polyhydroxyalkanoate (PHA) by Ralstonia eutropha JMP 134 with volatile fatty acids from palm oil mill effluent as precursors

    The highest volatile fatty acids (VFAs) concentration from palm oil mill effluent (POME) treated by anaerobic fermentation was achieved for a 1-day process when the main acids used were acetic, propionic and butyric acids. Polyhydroxyalkanoate (PHA) production with VFAs from POME as precursors in the fed-batch mode has advantages over batch mode, both in terms of its productivity and 3HV ...

  • Vermicomposting biotechnology: recycling of palm oil mill wastes into valuable products

    Abstract Background Palm oil mill effluent and palm press fiber are problematic wastes generated by the palm oil mill industries in Malaysia. This study has endeavored to assess the possibility of the vermicomposting of residue from the palm oil mills using epigeic earthworms Lumbricus rubellus under laboratory conditions. The study was conducted over 50 days using four combinations in ...

  • Fertilizer NPK from human urine and olive oil mill wastewaters

    The objective of this work was to determine how some wastewater acids could be used to prevent the decomposition of urea into ammonia during storage. The effect of storing human urine with olive oil mill wastewaters (OOMW) or water bubbled with CO2 (BW), was studied. Moreover, the application of two levels of urine dissolved in water OOMW, has been studied in relation to the properties of two ...

  • Olive oil Mill Wastewater properties change during infiltration through clay soils

    Olive oil Mill Wastewaters (OMW), are stored in clay basins in the region of Sfax (Tunisia). Field permeability measurements showed that the clay is not completely impermeable and its structure can be modified by the infiltration of OMW. Analysis of chemical composition of soil revealed the presence of phenolic compounds resulting from the percolation of OMW. An infiltration filled with clay and ...

  • Anaerobic degradation of palm oil mill effluent (POME)

    The biodegradation characteristics of palm oil mill effluent (POME) and the related microbial community were studied in both actual sequential anaerobic ponds in Malaysia and enrichment cultures. The significant degradation of the POME was observed in the second pond, in which the temperature was 35–37 °C. In this pond, biodegradation of major long chain fatty acids (LCFA), such as palmitic acid ...

  • Optimised treatment of Palm Oil Mill Effluent

    In this paper, we study experimentally the problem of separating oil from the oil?water emulsion that emulates Palm Oil Mills Effluent (POME). The investigations are focused on the effects of hydrochloric acid (HCl) and treatment conditions, e.g., operating temperature and magnetic stirring, on the separation process. The experiment results reveal that a higher flotation rate of oil is achieved ...

  • Trials about composting of solid wastes from palm oil Mills in Indonesia

    The solid wastes produced in palm oil mills are empty fruit bunch (EFB), mesocarp fibre, shell, and palm kernel cake. On an average the amount of EFB is 0,220 t of 1 t oil palm fruit bunch (Singh, 1994). In Indonesia, there will be about 2.9 million tonnes EFB (dry basis) in 2000 (Lubis et. al. 1994). At the moment, EFB in Indonesian palm oil mills are burnt in incinerators to reduce the mass and ...
