Abstract

Membrane technology has gained attention in wastewater treatment due to its great potential for producing high-grade water products for reuse. The membrane also effectively removes persistent pollutants in water effluent. However, their application is constrained by low productivity due to fouling formation. Incorporating functionalized nanoparticles into polymeric membranes has attracted much attention due to the improved membrane performance and additional features. Metal-organic frameworks (MOFs) incorporated into polymeric membranes have been widely applied in reverse osmosis (RO), forward osmosis (FO), nanofiltration (NF), and microfiltration (MF) for water and wastewater treatment. This short review presented recent findings, fabrication methods, and a systematic understanding of transport mechanisms under various operating conditions. This study also focused on several important parameters, such as improving physicochemical properties, membrane features, and performance enhancement in wastewater treatment. The reported studies show that MOFs incorporated membranes have reached >95% organic pollutants and 100% suspended solids. The membrane durability was also enhanced up to 140%, and the flux recovery can be maintained at 98% after several cycles. Even some MOFs, such as ZIF-8 and UiO-66, exhibited excellent performance in harsh conditions (pH < 4). The prospects and challenges of MOFs-incorporated membranes in industrial applications were also provided in this study.

Abstract

This study investigates the pyrolysis of Oil Palm Empty Fruit Bunches (OPEFB) using the open-source process simulation software DWSIM to evaluate the impact of temperature on product distribution, particularly bio-oil, biochar, and pyrolysis gas. OPEFB, an abundant lignocellulosic waste from Indonesia’s palm oil industry, holds significant potential as a renewable biomass feedstock. The simulation model was developed based on thermochemical conversion principles and was validated against selected experimental data from the literature. Results show that pyrolysis temperature significantly influences the yield and composition of the products. The gas yield increased with temperature up to 460°C, dominated by CO, CO₂, and H₂ due to the decomposition of volatile organic matter. However, gas yield declined beyond 460°C, likely due to secondary reactions converting gas precursors into liquid products. The optimal temperature was found to be around 510°C, offering a balanced yield of bio-oil and gas with minimal biochar formation. The chemical composition of bio-oil included furfural, phenols, alcohols, and acetic acid—compounds derived from the breakdown of cellulose, hemicellulose, and lignin. Biochar yield decreased with temperature, but its quality improved in terms of carbon content and fixed carbon fraction. This study highlights the utility of DWSIM as an accessible and transparent tool for simulating biomass pyrolysis. Future work should focus on refining the kinetic parameters, experimental validation of simulation results, and integrating downstream processing for fuel and chemical recovery.

Abstract

Produced water treatment remains a major challenge due to its complex contaminant composition and the limited efficiency and reusability of conventional photocatalysts. Polyoxometalate (POM)-based materials offer high redox activity and structural tunability. This study presents a novel tungsten-based polyoxometalate (W-based POM) composite with enhanced photocatalytic performance and kinetic superiority for produced water treatment. The objective of this work was to synthesize a reusable W-based POM composite and systematically evaluate its photocatalytic activity, adsorption behavior, kinetics, and stability. The composite was synthesized via a solvothermal method using Na₂WO₄·2H₂O and DMF. Photocatalytic experiments were performed by varying catalyst dosage (0.1–0.5 g), irradiation time (30-180 min), and reusability cycles. The W-based POM composite exhibited a rhombic polyhedral morphology with a well-organized three-dimensional POM framework, reduced crystallite size (14.8 nm), and compressive lattice strain, contributing to improved charge mobility. Optical analysis revealed a red-shift in the absorption edge, reducing the band gap from 2.80 eV to 2.25 eV and enhancing visible-light utilization. Photocatalytic experiments demonstrated high treatment efficiency, achieving 90% NH₃–N and 84% total dissolved solids (TDS) removal under UV irradiation within 180 minutes at an optimal dosage of 0.3 g. Adsorption behavior followed the Dubinin–Radushkevich and Temkin isotherm models, indicating an ion-exchange-dominated mechanism, while kinetic analysis revealed a multi-step process governed by intraparticle diffusion. The composite maintained stable performance over three consecutive cycles without significant activity loss. Overall, the results highlight the strong potential of W-based POM composites as efficient, reusable, and scalable photocatalysts for advanced produced water treatment.

Abstract

Agricultural wastewater poses significant environmental challenges due to its complex composition, including high concentrations of nutrients, organic matter, and emerging contaminants. Membrane-based technologies have emerged as advanced solutions for effective treatment and resource recovery from such effluents. This review provides a comparative analysis of various membrane systems—pressure-driven membranes, membrane bioreactors (MBRs), photocatalytic membranes, forward osmosis (FO), membrane distillation (MD), and adsorptive membranes—focusing on their performance in terms of pollutant removal, fouling behavior, energy consumption, and cost-effectiveness. Photocatalytic and FO membranes exhibit high potential for removing persistent organic pollutants and ensuring water reuse, while MD and MBRs demonstrate robust performance in nutrient and organic load reduction. Adsorptive membranes offer selective removal capabilities, particularly for antibiotics and pesticides, although scalability remains a concern. Advances in membrane materials, surface modifications, and hybrid system integration are paving the way for enhanced operational efficiency. The findings underscore the need for integrated, multi-barrier treatment approaches and continued innovation to meet the sustainability requirements of agricultural wastewater management..
