Nanotechnology offers several methods for water purification, including: - Nanofiltration: Using membranes with nanopores to filter out contaminants. - Nanoparticles: Materials like silver nanoparticles exhibit antimicrobial properties, killing bacteria and viruses. - Magnetic Nanoparticles: These can bind with pollutants and be removed using a magnetic field. - Photocatalysis: Similar to air purification, nanomaterials can degrade organic pollutants in water when exposed to light.
