Water system sterilization and reverse osmosis membrane protection in electric power and heavy industry

What is UV?

  • The ultraviolet wavelength is 100-400nm, divided into UV-A (320-400nm), UV-B (275- 320nm), UV-C (200-275nm) and vacuum ultraviolet
  • Ultraviolet sterilization is based on the absorption of ultraviolet light (200~280nm) by nucleic acid (DNA&RNA), which destroys the DNA of cells so that they cannot be repaired and reproduced.
  • Ultraviolet light (185nm) can also decompose many substances, such as organic matter TOC, residual chlorine, etc.

Process Benefits of UV

  • Reduces the use of chemicals, such as chlorine in the process, and leaves no toxic residues in the treated water
  • Does not impair the taste, smell and mouthfeel of the liquid (organoleptic properties)
  • Effective against all known microorganisms, including thermophilic bacteria (high temperature resistant) and chlorine-resistant pathogens, such as Cryptosporidium and Giardia, UV sterilization can usually provide a single treatment for most bacteria, viruses, and yeasts 4log (99.99%) kill rate (approximately 0.5 second contact time)
  • Can remove residual chlorine, reduce TOC
