PRODUCTION OF CHLORINE DIOXIDE

using diluted NaCL0₂ and HCL solutions

General

Oxiperm Pro systems produce chlorine dioxide using diluted solutions of sodium chlorite (NaClO₂) and hydrochloric acid (HCl). They are available in two capacity levels, producing 5 and 10g of chlorine dioxide per hour respectively. This capacity is sufficient to treat up to 50^m3 of drinking water per hour. Chlorine dioxide is produced on demand from diluted solutions using the reliable sodium chlorite / hydrochloric acid.

The chlorine dioxide solution produced is stored in an integrated tank and is added to the drinking water system as required using the integrated dosing pump.

Applications

In accordance with the 2001 Drinking Water Directive, which came into effect on 1 January 2003, the building operator is responsible for ensuring top-quality drinking water from the point at which the water provider makes his connection. The number of germs is not permitted to exceed a specific limit. Local health authorities are required by law to inspect public buildings regularly.

An ideal means of ensuring the cleanliness of the drinking water is to use chlorine dioxide as a disinfectant. Chlorine dioxide is highly effective against all types of germs and has a long dwell time in the system, which means it disinfects even without water being extracted. The big advantage of chlorine dioxide over other disinfectants is it's effectiveness against biofilms. It destroys the existing biofilm, thus removing the breeding ground for micro organisms, and prevents it from building up again.

Ideal application areas for Oxiperm Pro include combatting legionella in building installations and disinfecting small cooling systems.

No chance for Legionella

Legionella are rod-shaped bacteria that are present in almost all sources of water. These bacteria become pathogens when they enter drinking water systems and start to reproduce. The bacteria can enter the lungs when a person inhales mist droplets containing legionella when showering. They can cause a life threatening form of pneumonia known as legionellosis. The ideal breeding ground for legionella in drinking water systems can be found in biofilm, a slimy layer on the inside of water pipes and tanks, where other pathogens also build up and reproduce. Legionella also establish themselves in a amoebae, which offer them protection against conventional disinfection methods.

Using Oxiperm Pro ensures reliable removal of the biofilm with all pathogens and legionella present in piping and prevents reinfestation.
