What are common methods of water disinfection?

Chlorination, UV treatment, and ozonation are widely recognized methods of water disinfection that effectively eliminate pathogens and improve water quality.

Chlorination involves adding chlorine to water, which kills bacteria, viruses, and other microorganisms. It is one of the most common and cost-effective methods used in water treatment facilities.

UV treatment utilizes ultraviolet light to destroy the DNA of microorganisms, rendering them unable to reproduce. This method is effective against a wide range of pathogens and is often used in conjunction with other disinfection methods to enhance overall water safety.

Ozonation involves the introduction of ozone gas into water, which acts as a powerful oxidant that can destroy bacteria, viruses, and other contaminants. Ozone is effective in breaking down organic matter and is sometimes preferred for its ability to leave no residual chemicals in the water.

Thus, these methods are integral to ensuring safe drinking water and preventing the spread of waterborne diseases. In contrast, the other methods listed primarily focus on treatment processes that do not directly disinfect water or are less effective for microbial removal.
