Abstract
Activated carbon-based filtration systems have emerged as one of the most effective and sustainable technologies for water purification, owing to their exceptional adsorption capacity, high surface area, and tunable surface chemistry. This review highlights recent developments in activated carbon filtration for efficient water treatment, focusing on material synthesis, modification techniques, adsorption mechanisms, and practical applications. Advances in the preparation of activated carbon from renewable biomass, agricultural residues, and industrial by-products have significantly enhanced cost-effectiveness and environmental sustainability. Surface functionalization and nanocomposite integration have further improved the removal efficiency of contaminants such as heavy metals, dyes, pharmaceuticals, and organic pollutants. Additionally, hybrid filtration systems combining activated carbon with membranes or photocatalytic materials have shown remarkable performance in achieving higher purification rates and reusability. Despite these advancements, challenges remain in regeneration efficiency, adsorption selectivity, and large-scale implementation. This review underscores the importance of developing advanced, low-cost, and eco-friendly activated carbon filters to meet the growing demand for safe and clean water, while also emphasizing future research directions toward scalable and sustainable water treatment technologies.
