Abstract

The TiO₂/UiO-66-NH₂ composites synthesized through a hydrothermal method, demonstrated a significant enhancement in photocatalytic activity under visible light, offering a promising solution for the treatment of pollutants in produced water. These composites exhibited exceptional photocatalytic adsorption and degradation capabilities, efficiently removing various contaminants. The adsorption process during pollutant removal was effectively modeled by both the Freundlich and Langmuir isotherms, indicating the heterogeneous nature of the adsorption sites and the monolayer adsorption behavior, respectively. The composites achieved impressive removal efficiencies of 88.46% for NH₃-N and 81.97% for total dissolved solids (TDS), underscoring their potential to address common pollutants in produced water. UV-vis spectroscopy analysis revealed a band gap energy of 2.28 eV for the TiO₂/UiO-66-NH₂ composites, which is lower than that of pure TiO₂, contributing to enhanced photocatalytic performance under visible light. This reduced band gap improves the material's ability to absorb visible light, thereby facilitating more efficient degradation of organic pollutants. Furthermore, the pseudo-second-order kinetic model best described the adsorption process for both TiO₂ and TiO₂@UiO-66-NH₂ composites, suggesting that chemisorption is the dominant mechanism for NH₃-N removal. This indicates that the composites exhibit a high affinity for NH₃-N, effectively removing it from produced water. Overall, the TiO₂/UiO-66-NH₂ composites provide a promising approach for mitigating contaminants in produced water, demonstrating their potential for use in both environmental and industrial water treatment applications.

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..

Abstract

The contamination of water resources with pharmaceutical pollutants, particularly tetracycline (TC), has become a pressing environmental issue. This poses a significant threat to ecosystems and public health, as untreated wastewater can lead to the spread of antibiotic resistance. In this study, we explore the potential of PVDF-based membranes integrated with WO₃/ZnO composites for effectively removing TC and COD from wastewater. Membranes with varying concentrations of WO₃/ZnO (0.25%, 0.75%, 1.25%) were evaluated in terms of flux, pollutant rejection efficiency, and pore properties. Among the tested membranes, MV-3 (PVDF neat 13% + WO₃/ZnO 1.25%) demonstrated the best performance, achieving 98.28% rejection for TC and 87.72% for COD. Additionally, MV-3 exhibited the highest porosity (67.81%), although flux decreased moderately. This highlights the trade-off between high rejection efficiency and flux but demonstrates that the addition of WO₃/ZnO to PVDF membranes can provide a balanced solution for efficient wastewater treatment.

Abstract

Produced water contains complex mixtures of organic and inorganic contaminants that are difficult to remove using conventional treatment methods. This study proposes a hybrid treatment system combining zeolite adsorption as a pretreatment and a PVDF–TiO₂@UiO-66-NH₂ photocatalytic membrane for enhanced produced water purification. The zeolite adsorption process effectively reduced pollutant load prior to membrane filtration, with kinetic analysis indicating that NH₃–N removal followed the pseudo-second-order model (R² ≈ 0.977), suggesting a chemisorption mechanism. Under light irradiation, the photocatalytic membrane demonstrated enhanced performance due to the generation of reactive oxidative species, resulfyting in improved contaminant degradation and flux stability. The optimal membrane (2 wt% TiO₂@UiO-66-NH₂) achieved removal efficiencies of approximately 36% for TDS, 62% for COD, and 80% for NH₃–N. The overall results demonstrate a strong synergistic effect between adsorption, photocatalysis, and membrane filtration, leading to improved treatment efficiency and reduced fouling potential. This integrated approach offers a promising and sustainable solution for produced water treatment.
