What are the common methods of water disinfection?

Water disinfection is crucial for preventing the transmission of waterborne diseases and ensuring the safety of drinking water. There are several common methods used to disinfect water. Chlorination is the most widely used method, which involves adding chlorine in the form of chlorine gas, sodium hypochlorite, or calcium hypochlorite to the water. Another method is ozonation, where ozone gas is injected into the water to kill bacteria and viruses. UV irradiation is another effective technique that uses ultraviolet light to destroy pathogens. Filtration processes such as using activated carbon filters or ceramic filters can also remove microbial contaminants. Lastly, chloramines, a combination of chlorine and ammonia, can be used as a disinfectant. Each method has its benefits and limitations, and the choice of disinfection method depends on the specific requirements and constraints of the water treatment system.
