How does an ultraviolet irradiator function in water treatment?

An ultraviolet irradiator functions in water treatment by utilizing ultraviolet (UV) light to destroy microorganisms. This method of disinfection is effective as UV light penetrates the cell walls of bacteria, viruses, and protozoa, damaging their DNA or RNA and rendering them incapable of reproduction and infection.

This non-chemical approach has the advantage of not altering the taste or chemical composition of the water, making it a preferred method for ensuring water safety without the use of potentially harmful chemicals. The effectiveness of UV irradiation is well-documented in terms of pathogen elimination, making it a valuable tool in maintaining water quality and safety for drinking purposes.
