Several methods can be used to purify water, including:
1. Boiling: Boiling water for at least 1-3 minutes can kill most pathogens, making it safe for consumption. 2. Filtration: Using physical barriers to remove impurities and contaminants can be effective. Filters can range from simple household units to advanced systems used in healthcare settings. 3. Chemical Disinfection: Adding chemicals like chlorine or iodine to water can kill microorganisms. This method is often used in emergency situations. 4. Ultraviolet (UV) Light: UV light can destroy the DNA of microorganisms, rendering them harmless. This method is increasingly popular in healthcare settings. 5. Reverse Osmosis: This advanced method uses a semi-permeable membrane to remove ions, molecules, and larger particles. It is highly effective but can be expensive.
