The use of UV lamps is meant for both Germicidal and TOC reduction, which results in additional organic and microbiological reduction.
Feed water (Process Water) is exposed to UV radiation emitted from UV lamps that emit both 185nm and 254nm wavelength radiation. The lamp is protected inside a highly transmissive quartz tube. The reaction takes place in the UV Reactor that that would contain a single or a bank of lamps.
The UV rays emitted from the lamp disassociate the free chlorine through a photochemical reaction, which breaks the Cl - Cl bond. The resulting products are chlorine ions (Cl-) and Hydrochloric Acid (HCl), which are then removed from the process water.
