Micro-organisms present in process water can be destructed by ultraviolet (UV) light. By exposing the water to UV-radiation of 254 nm, the DNA of the micro-organisms is broken and becomes inactive. UV-radiation of 185 nm oxidizes organic substances including trihalomethanes (THM's). Other organic substances are weakly electrically charged so these can be removed usingCEDI. UV-radiation of 185 nm is also destructive for micro-organisms.
- Micro-organisms are destructed or deactivated immediately, without exposure time
- Safe and environmentally friendly: no chemicals are needed so no chemical waste.
- Over dosage is impossible
- Low investment and process costs
- Simple installation and maintenance
- Usable in combination with other water treatment techniques
