TOC removerTOC Reduction Using UV TechnologyReduction of Total Oxidizable Carbons (TOC's) in water is achieved via three types of reactions initiated by UV that work to destroy and/or remove oxidizable carbons.
The primary UV/chemical reaction is an oxidation process that begins when high-energy 185 nm UV dissociates water molecules, thereby creating hydroxyls (free OH- radicals). The hydroxyls created by UV are highly reactive and readily combine with other molecules, such as the hydrocarbon molecules that make-up TOC's. When hydroxyls combine with the TOC hydrocarbons they form water and carbon dioxide molecules; TOC's are destroyed and the oxidation is complete.
The second type of UV reaction that works to remove TOC's is one whereby the ultraviolet photons dissociate organic molecules directly. This result is TOC removal by means of destruction. A third UV reaction occurs when deionization is added downstream of a UV reactor. Ultraviolet energy will ionize TOC's, which allows for subsequent removal by a deionization system.
Working principle for UV to remove TOCIn the high-purity water system, the UV equipment is often connected with the ion exchanger to reduce the trace organic substance in the water, named TOC (total organic carbon). The high-energy UV lamps emit the UV light (1 85nm) of wavelength below 200nm, which can excite the photolysis of water and generate the hydroxide ion (OH) high super-high energy. Generally, this system can reduce the TOC of tap water or underground water sources to 1 .5ppb and lower, reaching the standard for high-purity water.
