Disinfection

Ultraviolet light (UV) is highly effective at combatting bacteria and viruses – and also for oxidising organic species in water, when utilising medium-pressure polychromatic lamp technology.

Ultraviolet disinfection is a physical, chemical-free process that directly attacks the DNA of the bacteria, including parasites such as Cryptosporidium or Giardia, which are extremely resistant to chemical disinfectants. In addition, it reduces chloramines by a variety of mechanisms.

UV technology has advanced to the point where it can easily enhance the disinfection and oxidation of all sorts of pools.

Ozone gas is a highly active form of oxygen, hundreds of times more powerful and effective than chemical treatments such as chlorine. Ozone oxidises the urea/ammonia responsible for chloramine production as well as the chloramines formed. This precursor reduction also lowers the levels of THM (trihalomethane) disinfection by-products.

Generated on-site, ozone gas dissolved in water kills all bacteria and viruses leaving water with the highest level of clarity and brightness, free from odour and taste. All SUEZ triogen® O3 ozone systems operate under full vacuum, thus eliminating the risk of ozone gas leakage.

The SUEZ triogen® Advanced Oxidation Process (AOP) is an advanced, chemical-free technology that helps destroy organic pollutants and chlorine-resistant organisms.

AOP combines ozone gas and UV light to form highly reactive hydroxyl-free radicals, which accelerate the decomposition of organic pollutants, and offers excellent pathogen control. The UV light also photo-chemically destroys any residual ozone in the water, thus removing the need for de-ozonation equipment.

The triogen® AOP process, which operates under full vacuum, is the culmination of 30 years’ research and expertise in water treatment.
