Ultraviolet (UV) light has become widely accepted as an alternative for chlorination, ozonation, and heating of water. Use of UV light has proven to be harmless for humans, animals and environment. UV light protects against pathogens and food-spoiling micro-organisms.
The UV sensitivity of micro-organisms differs per species. Each water type has its specific properties and requirements. The use of UV equipment to protect against micro-organisms has thus to be judged and advised by specialists only.
Ultraviolet light is part of the electromagnetic spectrum, to be found between visible light (above 400nm) and X-rays (below 40nm). Depending on the application certain UV areas and/or wavelengths are important e.g.:
- disinfection: 200 – 300nm (optimum at 200 and 265nm)
- deozonation: 200 – 300nm (optimum at 250nm)
- advanced oxidation processes: 200 – 260 (optimum at 200nm)
- dechloramination: 200 – 400nm (optimum. at 245, 290, 360nm)
- dechlorination: 200 – 350nm (optimum 300nm)
- OH-radical formation from TiO2: >365nm
So, each process needs a specific approach in use of ultraviolet light to effectively treat the water.
