Advanced Water Purification Techniques for Sustainable Clean Water Management: A Comprehensive Review
The growing global demand for safe drinking water, coupled with increasing pollution from industrialization, urbanization, and agricultural activities, has intensified the need for efficient and sustainable water purification technologies. Conventional water treatment processes often fail to remove emerging contaminants such as pharmaceuticals, microplastics, endocrine-disrupting compounds, and heavy metals. Advanced water purification technologies—including membrane filtration, advanced oxidation processes (AOPs), nanotechnology-based adsorbents, photocatalysis, electrochemical treatment, and bio-inspired purification systems—have emerged as promising solutions for addressing complex water contamination challenges. This review critically examines the principles, efficiency, advantages, and limitations of modern water purification techniques. Comparative analysis of these technologies is provided in terms of removal efficiency, cost, scalability, and environmental sustainability.
