UV Water Treatment Technology – Degradation of Residual Chlorine
In municipal water treatment and water supply systems, chlorination is necessary. The method of eliminating residual chlorine has an activated carbon bed and chemical treatment. A disadvantage of activated carbon water treatment is that it requires constant regeneration and often encounters problems with bacterial growth. Ultraviolet light at 185 nm and 254 nm has been shown to effectively destroy the chemical bonds of residual chlorine and chloramine. Although it requires a lot of ultraviolet energy to work, the advantage of UV water treatment technology is that it does not need to add any drugs to the water, does not need to store chemicals, is easy to repair, and also has the effect of sterilization and removal of organic matter.
