Disinfection System with UV Radiation for Municipal Wastewater Treatment

UV disinfection has many advantages:
Immediate and safe destruction of the bacteria without addition of chemica
Photochemical reduction of undesirable substances
No THM or AOX formation, no formation of other undesirable substances
No impairment of odour or taste of the water
No storage and handling of chemicals required
Effect is independent of pH
No reaction vessel or reaction tank required
Low space requirement
Low investment and operating costs with high reliability and efficiency

UV Water Disinfection
UV disinfection of water is a non-chemical, non-heat application which kills bacteria, viruses, moulds, yeasts and protozoa in water.

Potable water, ingredient and food processing water can all be treated with ultra violet without change to flavour or colour.

UV effectively deactivates bacterial problems and pathogens in wastewater and secondary effluent.

UV disinfection is effective, economical, safe, fast, easy, automatic and chemical free.

Importantly, UV kills protozoa such as Giardia and Cryptosporidium, which cannot be destroyed by chlorine.

Working Principle

Disinfection process Ultraviolet(U.V.) disinfection of water consists of a purely physical, chemical-free process. UV-C radiation in particular, with a wavelength in the 240nm to 280 nanometers range, attacks the vital DNA of the bacteria directly
The radiation initiates a photochemical reaction that destroys the genetic information contained in the DNA. The bacteria lose their reproductive capability and are destroyed. Even parasites such as Cryptosporidia or Giardia, which are extremely resistant to chemical disinfectants, are efficiently reduced. UV can also be used to remove chlorine and chlormaine species from water this process is called photolysis, and requires a higher dose than normal disinfection.
