Wasserreinigung, or 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, sedimentation, and chemical treatment. The goal is to eliminate harmful substances, including bacteria, viruses, and pollutants, ensuring that the water meets health standards. Different technologies are used in Wasserreinigung, including reverse osmosis, activated carbon, and UV disinfection. These methods can be applied in various settings, from large-scale municipal water treatment plants to small home filtration systems. Proper water purification is essential for public health and environmental protection.
