Abstract

This study provides a thorough evaluation of a flow capacitive deionization (FCDI) system using chemically modified activated carbon for improved fluoride removal from wastewater. Current literature indicates a gap in optimizing carbon modification techniques to enhance FCDI efficiency. The research systematically investigates an optimal alkali-to-carbon ratio of 2:1, which significantly enhances the specific surface area and pore structure of activated carbon, correlating with improved adsorption capacities and lower effluent fluoride concentrations. Durability tests across multiple operational cycles show consistent fluoride removal efficiency and minimal conductivity variations in the effluent. Additionally, the effects of operational parameters such as voltage and hydraulic retention time (HRT) are explored, demonstrating that extended contact times and optimized electrical settings further enhance system performance. The findings indicate that the modified FCDI system offers significant potential for sustainable, large-scale applications in municipal and industrial wastewater treatment, combining high efficiency with robust performance. This research establishes a foundation for future advancements in FCDI technology, aiming for cost-effective and environmentally sustainable water treatment solutions.

在 FCDI 系统中使用改性活性炭提高废水中氟化物的去除率

本研究对使用化学改性活性炭的流动电容式去离子（FCDI）系统进行了全面评估，以提高废水中氟化物的去除率。现有文献表明，在优化碳改性技术以提高 FCDI 效率方面还存在差距。这项研究系统地研究了 2:1 的最佳碱碳比，它能显著提高活性炭的比表面积和孔隙结构，从而提高吸附能力并降低出水氟化物浓度。多个运行周期的耐久性测试表明，除氟效率始终如一，出水电导率变化极小。此外，还探讨了电压和水力停留时间（HRT）等运行参数的影响，结果表明，延长接触时间和优化电气设置可进一步提高系统性能。研究结果表明，改进型 FCDI 系统集高效率和稳健性能于一身，为市政和工业废水处理领域的可持续大规模应用提供了巨大潜力。这项研究为 FCDI 技术的未来发展奠定了基础，旨在提供具有成本效益和环境可持续性的水处理解决方案。

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
