Chlorine Dioxide, Disinfection & Water Hygiene

Chlorine dioxide for water disinfection

Chlorine dioxide is highly effective when used to clean and disinfect water systems, it is especially good for legionella control activities. Water hygiene is concerned with the effective management and disinfection of water to prevent pathogen proliferation, especially in stored water systems.

Chlorine dioxide is a highly effective oxidising biocide that is effective against both planktonic and sessile bacteria, including Legionella bacteria making it ideal for use in the disinfection and sterilisation of water systems.

Chlorine dioxide is highly effective against legionella

Because of its highly effective biocidal characteristics, chlorine dioxide is ideal for use in water hygiene activities.

Chlorine dioxide has consistently been shown to be one of the best molecules for eradicating the causative organism of both Legionnaires’ disease and Listeriosis.

It also controls other potentially dangerous bacteria such as Salmonella, Shigella, E. coli and other coliforms.

It is also effective against Giardia cysts, algae and amoebae, planktonic and sessile organisms.

Chlorine dioxide effectively destroys biofilm whilst providing a lasting residual throughout the distribution system to prevent its reformation.

Best available technology for water systems

In the UK, the Building Services Research and Information Association (BSRIA) has recommended chlorine dioxide as the best available technology for control of legionella in hot and cold water systems.
