ABSTRACT : The rapid industrialization and urban expansion of recent decades have resulted in large volumes of wastewater contaminated with heavy metals, dyes, organic pollutants, and pathogens. Conventional wastewater treatment technologies often fail to achieve complete pollutant removal and are energy-intensive. Nanotechnology has emerged as a revolutionary field, offering promising materials and techniques for enhanced wastewater purification and pollution control. Nanoparticles, nanomembranes, carbon nanotubes, and photocatalytic nanomaterials exhibit exceptional adsorption, filtration, and degradation properties, enabling efficient treatment of complex contaminants. This paper explores the potential of nanotechnology in wastewater treatment, including nanofiltration membranes, nano-adsorbents, nanocatalysts, and disinfection systems. Key challenges such as material toxicity, high production costs, and environmental safety are also addressed. Furthermore, strategies for integrating nanotechnology into large-scale wastewater treatment plants are discussed. By examining recent advancements and practical applications, this study highlights how nanotechnology can contribute to sustainable pollution management and support global water security.
