Ozone Testing

Ozone is a powerful and fast-acting disinfectant and can purify water 3000 times faster than chlorine. Ozone disinfection works by breaking through the cell membrane of the microorganisms and destroying the DNA, enzymes and proteins inside the bacterial cell. This kills the cell by a process known as lysis.

Unlike chlorine, there are no disinfection by-products (DBPs) associated with ozone disinfection as ozone breaks down into oxygen.

Ozone is unstable, and although it is produced naturally in the environment by reactions with UV light, industrially it must be made using an in-situ generator. If ozone is used as a disinfectant, it must be monitored regularly to ensure adequate disinfection and effective removal of harmful pathogens from the water.

  • Drinking water – Ozone is often used a pre-treatment prior to sand or active carbon filtration. Ozone must be generated in-situ using an ozone generator as it is too unstable to be stored. Ozone must be monitored to ensure adequate disinfection of the water.
  • Pool and spa – Ozone is used as an alternative to chlorine-based disinfectants. Ozone is particularly effective at killing Cryptosporidium and Giardia, both of which are unaffected by chlorine disinfection. Ozone also does not affect the pH of the water but does have a large initial cost and cannot be used as the sole disinfection method.
