Ultraviolet (UV)

Ultraviolet (UV) light is a form of electromagnetic radiation that is used in various applications, including water treatment. Ultraviolet water treatment involves the usage of UV-C radiation which has a wavelength of 200-280 nanometres (nm), to destroy or inactivate microorganism such as bacteria, viruses, and protozoa that may be present in water. The ultraviolet light damages the DNA of the microorganisms, preventing and rendering them from reproducing and causing harm if utilised or consumed. Ultraviolet water treatment is commonly used in municipal water treatment plants, as well as in homes and businesses that reply on private wells for their water supply. One of the many advantages of ultraviolet water treatment is that it does not utilise any chemical compounds to achieve its results but will require electricity to function and perform its task. Additionally, ultraviolet water treatment is effective against a wide range of microorganism and does not alter the taste or odour of water. However, it does not remove other contaminants such as heavy metals, pesticides and chemicals, and therefore may need to be used in combination with other water treatment methods to ensure water safety.
