“…On the other hand, the activated sludge was used for melanoidin removal from the POME. 63.45 % of pigment removal has been found when the active bacteria were accumulated for 31 days and supplemented with yeast extract and diary waste [48]. Moreover, the dark color of the POME has been treated using microwave-irradiated abundant palm oil mill boiler ash as a biosorbent.…”

Melanoidin is the main cause of the dark brown color of the palm oil mill effluent (POME) that form under the Maillard reaction. In this study, the constructed wetland integrated with microbial fuel cell (CW-MFC) has been developed for melanoidin removal from the POME and simultaneously electricity generation as a by-product. The macrophyte Dieffenbachia sp. has been used as a biocatalyst on the cathode electrode and the oxidoreductase-producing bacterium Bacillus lichenformis with laccase and manganese peroxidase activity has been used as an anodic biocatalyst. The maximal melanoidin removal, chemical oxygen demand (COD) removal, enzyme activity, and power output were monitored. The maximal laccase and manganese peroxidase activities of 1.60 ± 0.10 U/mL and 1.45 ± 0.05 U/mL were found during melanoidin degradation. In addition, the maximal melanoidin removal of 93.59 ± 0.10% and 95.12 ± 0.15% were achieved respectively. When the maximal power density of 0.18 ± 0.01 mW/m3 was generated. This study gained new knowledge about using the CW-MFC system as a biological treatment process of the melanoidin content in the POME and simultaneously generated electrical energy as a by-product. HIGHLIGHTS The coupling process of constructed wetland and the microbial fuel cell is promising for the melanoidin removal of the POME The maximal melanoidin removal of 93.59 % was gained The maximal power output of 0.18 mW/m3 was generated from this system GRAPHICAL ABSTRACT

“…In order to enhance the activated sludge process, yeast-extract and dairy-waste was augmented into activated sludge by Abdulsalam et al [44] and they studied the performance efficiency for anaerobically-treated POME. At an organic loading rate of 0.895 g COD/ L day, a remarkable COD and TSS removal performance showed a reduction of 92.58% and 96.89% that was obtained after 31 days of retention, respectively, while 57.99% and 46.25% were obtained for conventional sludge after retention for 87 days, respectively.…”

Undoubtedly, industrial activities have produced a large amount of waste, which has significantly contributed to the global environmental problem. The palm oil sector, which is considered a water-intensive industry, is one of the industrial sectors that have become a major source of severe water pollution concerns. Normally, 50% of the freshwater used during the extraction of crude palm oil will end up in the production of undesirable liquid waste. Thus, proper regulation and enforcement are required to control the discharge of such waste to ensure the sustainability of water resource management. Based on research databases such as Scopus, ScienceDirect, Web of Science and PubMed the total number of publications focused on palm oil mill effluent (POME) treatment has increased significantly over the past five years. The increase in publications shows the growing concern about the POME issue among the scientific community. This mini review focuses on selected biological treatment techniques for remediation of POME focusing on ponding systems, bioadsorption, activated sludge, microorganism and plant, aerobic biodegradation and integrated/hybrid treatment strategies. The summary of optimum operating conditions, characteristics of the treatment system, properties of materials and performance of each treatment are discussed in detail. To achieve a high level of contaminant removal performance, it is critical to discover the synergistic effect between the treatment procedures, materials employed, operational cost, and circumstances.
