Summary: The large quantities of palm oil mill effluent (POME) create a significant pollution problem. In this study, we demonstrate that the introduction of plasma and MHz-order sound waves can greatly reduce the treatment time and improve the removal of pollutants in POME. Plasma exposure enhances oxygen dissolution and organic compound dissolution, while sound waves promote convective mass transfer and bacterial decomposition. Combining plasma pretreatment and sound wave irradiation can lead to a fivefold reduction in the total treatment duration, making this hybrid technology promising for industrial-scale treatment systems.

Summary: This study suggests that using palm oil mill effluent (POME) as a carbon source for biological hydrogen production can be improved through chemical pre-treatment. Among various chemical pre-treatments, phosphoric acid (H3PO4) showed the best results with the highest biohydrogen production and yield. Continuous fermentation under optimal conditions further increased biohydrogen production. Bacterial community analysis revealed the presence of specific bacteria involved in biohydrogen production in the continuous system.

Summary: The rapid expansion of the palm oil industry poses a potential threat to the terrestrial environment and aquatic ecosystems due to the discharge of high volumes of solid and liquid waste substances during oil processing. Phytoremediation using water spinach has shown potential in improving the quality of palm oil mill effluent (POME). Results indicate that water spinach is efficient in reducing COD, nitrate, phosphate, and color in POME up to 75%, with no negative impact on growth performance. However, high concentrations of POME can damage root structures and affect the growth of water spinach over time.

Summary: The study investigated the biohydrogen and biomethane potential of palm oil mill effluent (POME) in a two-stage anaerobic digestion system under thermophilic and mesophilic conditions. The results showed that the best production potentials were obtained from POME with an initial 0.5 g-COD loading, and the energy yield achieved from two-stage AD was significantly higher than single-stage AD. Continuous production of hydrogen and methane revealed that the highest yields were generated at specific hydraulic retention times, with an overall COD removal of approximately 66.27%.
