Palm oil mill effluent (POME) is palm oil processing industrial waste that cannot be discharged directly into water bodies. Therefore, this waste must be treated. One method that can be used to treat it is coagulation. The purpose of this study was to investigate the effect of coagulant doses on the coagulation process for treating the POME through experimental and kinetic analysis. The alum dose was varied to 1, 3, 5, 10, 15 g/L. The volume of treated waste was 1 L. Before adding alum, the pH of POME was adjusted to 7.0 with the addition of technical grade NaOH. The coagulation process was carried out for 180 minutes at room temperature. Every 20 minutes, the pH of the liquid was measured and a fluid sample as much as ±50 mL was taken to be settled for 24 hours. Next, the total suspended solid (TSS) concentration in the supernatant was analyzed. The results showed that the addition of alum could decrease the liquid pH and increase the TSS of the liquid. The coagulation process for 180 minutes resulted in a TSS reduction efficiency of 33.3, 33.3, 37.1, 1.7, -17.8% at alum doses of 1, 3, 5, 10, 15 g/L respectively. The first-order kinetic model provided a better prediction than the second-order kinetic model with R2 values of 0.7876-0.9707 and 0.2746-0.8912, respectively.

“…Palm oil mill effluent (POME) is one of the predominant pollutants in Southeast Asia. Specifically, the production of palm oil is abundant in Indonesia, Malaysia, and Thailand, which produce a large volume of effluents with a high organic carbon content. , The discharge of POME on arable land creates environmental distress due to its high concentration of biochemical oxygen demand (BOD) and chemical oxygen demand (COD). Therefore, POME must be treated before it is discharged into the natural environment.…”

“…The ponding system has low maintenance costs due to operational and process simplicity; therefore, it is economical and considered to be a feasible means of treating high-strength organic wastewater. , However, it entails a long hydraulic retention time (generally 40–200 days) and a large land area (∼1–5 ha). Moreover, it is not considered environmentally friendly because the methane produced by this technique is wastefully released into the atmosphere, and the system cannot be certified for carbon emission reduction trading. , In some cases, POME was subjected to physical and chemical pretreatment consisting of coagulation and flocculation aid, sedimentation, and adsorption using activated carbon or membrane filtration . However, the applicability of a wastewater-processing system associated with a higher cost might be unpersuasive to the palm oil millers.…”

The wastewater burden and increased energy demands have spurred interest in finding possible solutions that could concomitantly address both issues. Microbial lipid production, together with the bioremediation of wastewater, could be a promising solution to address both problems. In this context, the present study was designed to evaluate the potential of Bacillus cereus (B. cereus) for accumulating microbial lipids through the bioremediation of palm oil mill effluent (POME) in batch mode fermentation. Different dilutions of POME media (25%, 50%, 75%, and 100%) were used to determine the optimum POME concentration for enabling the maximum yield of biomass and maximum lipid production. The 50% (v/v) POME was found to have potential for the highest biomass growth (8.09 g/L) and lipid accumulation (1.46 g/L), with a lipid content of 18.04% (dry weight basis). B. cereus accumulated a higher biomass and lipid content than other bacterial strains, such as Rhodococcus opacus and Pseudomonas aeruginosa, under similar conditions. On the other hand, the degree of bioremediation was assessed by evaluating several wastewater parameters and determining the seed germination index (GI) of Vigna radiata. POME treated with B. cereus displayed higher GI values than the untreated samples due to the significant remediation of detrimental organics present in the POME. This finding was further confirmed by the substantial reduction in pollution load, particularly in chemical oxygen demand (COD) and biochemical oxygen demand (BOD) for 50% POME, thus demonstrating removal efficiencies of 79.35% and 72.65%, respectively. Therefore, the results of this study suggest that B. cereus cultivation in POME could be a promising technique for attaining higher biomass growth and lipid production in conjunction with the bioremediation of POME. The approach of achieving dual objectives that is utilized in the present study provides a novel strategy for palm oil millers.

Applications of nanotechnology in oil and gas industry: Progress and perspective

Nanotechnology has been successfully implemented in many applications, such as nanoelectronics, nanobiomedicine, and nanodevices. However, this technology has rarely been applied to the oil and gas industry, especially in upstream exploration and production. The oil and gas industry needs to improve oil recovery and exploit unconventional resources. The cost of research and oil production is under immense pressure, and it is becoming more difficult to justify such investment when the crude oil price is weak and depressed. There is a widespread belief that nanotechnology may be exploited to develop novel nanomaterials with enhanced performance to combat these technological barriers. Increasing funding resources from governmental and global oil industry have been allocated to exploration, drilling, production, refining, and wastewater treatment. For example, nanosensors allow for precise measurement of reservoir conditions. Nanofluids prepared using functional nanomaterials may exhibit better performance in oil production processes, and nanocatalysts have improved the efficiency in oil refining and petrochemical processes. Nanomembranes enhance oil, water and gas separation, oil and gas purification, and the removal of impurities from wastewater. Functional nanomaterials can play an important role in the production of smart, reliable, and more durable equipment. In this review paper, we summarize the research progress and prospective applications of nanotechnology and nanomaterials in the oil and gas industry.
