Smart and innovative nanotechnology applications for water purification

The most critical challenge of the twenty-first century is to provide sufficient clean, cheap water for all. This is made worse by population increase, climate change, and declining water quality. Technology innovation, such as nanotechnology, is essential for enabling integrated water management to increase treatment effectiveness and expand water supplies using unconventional water sources. Nanotechnology can improve access to clean, safe drinking water by providing innovative nanomaterials for treating surface water, groundwater, and wastewater contaminated by hazardous metal ions, inorganic and organic solutes, and microorganisms. As a result, the development of nanotechnology provided ground-breaking solutions to issues in engineering, physics, chemistry, and others. The products and processes developed because of advancements in nanotechnology currently employed in wastewater treatment include nanoadsorbents, nano zero valent iron, nanobiocides, nanofiltration, magnetic nanoparticles, and hybrid technology provides for catalytic wet air oxidation in addition to nanoparticles. Considering the essential need to examine and handle the developing hazardous wastes with lower costs, less energy, and more efficiency, this review shines a light on the current advancements in nanotechnology. Numerous industries, such as scientific research, the medical field, and the food industry, have paid close attention to the expanding significance of nanotechnology and the unique qualities of nanobubbles.
