Water purification is the process of removing contaminants from water to make it safe for drinking and other uses. This can involve various methods, such as filtration, boiling, and chemical treatment, to eliminate harmful bacteria, viruses, and pollutants. Clean water is essential for health and well-being, as contaminated water can lead to serious illnesses. Different technologies are used in water purification, including reverse osmosis, activated carbon, and UV light. Each method has its advantages and is chosen based on the specific contaminants present in the water. Ensuring access to purified water is crucial for communities worldwide.
