Nanomaterials for Water Purification Towards Global Water Crisis Sustainable Solutions

Abstract

Providing the world's increasingly growing population with clean, affordable water is an unprecedented challenge for the 21st century. In the face of climate change and failing water quality, nanotechnology has become the center piece in innovation in this global crisis. This article discusses the ways in which nanomaterials are leading the way in the revolution of the water purification techniques and are providing sustainable means to increase access to safe drinking water around the world. Water scarcity and pollution threaten human health, economic development and environmental sustainability. Traditional water treatment methods do not generally achieve effective removal of emerging pollutants and pathogen. Thus, the properties of nanomaterials at the molecular scale make it unique, and open new possibilities for development of more efficient, cost effective and environmentally friendly water purification. Nanotechnology is changing the way we clean and reuse water resources from nano adsorbents that remove toxic metals selectively and nanomembranes that filter out the slightest contaminants. In this article we will look at the advances in nanomaterials for water purification looking at how they work, what they are good for, and they could help enlighten us about the global water crisis. Through these innovations we’ll explore ways these are redefining the future of water management for anyone and everyone, not just industries and communities, but all across the globe.
