Water Treatment and Purification One of the most important ways to ensure a sufficient supply of safe water is through proper treatment and purification. Water treatment involves removing impurities and contaminants from water to make it safe for human consumption. This can be done through a variety of methods, including filtration, disinfection, and reverse osmosis. Filtration is the process of removing solid particles from water by passing it through a filter. Sand filters and activated carbon filters are commonly used to remove physical impurities such as sediment and debris. Disinfection is the process of killing or removing harmful microorganisms from water. Chlorination and ultraviolet (UV) light are two commonly used methods of disinfection. Reverse osmosis (RO) is a process that uses a semi-permeable membrane to remove dissolved impurities, including bacteria and viruses, from water.
