Water purification is the process of removing impurities and contaminants from water to make it safe for drinking, cooking, and other uses. This can involve various technologies such as filtration, distillation, and disinfection to remove harmful substances such as bacteria, viruses, chemicals, and pollutants. Water purification is essential for public health and environmental protection, as access to clean and safe drinking water is crucial for human well-being. Researchers in this area work to develop new and improved methods for water treatment, as well as strategies for water management and conservation.
