CHLORINE DIOXIDE – Effective, Lasting Protection Against all Germs and Biofilms

Chlorine dioxide for long-control of dangerous germs and prevention of biofilm formation.

Chlorine dioxide ( CLO2 ) provides excellent, lasting disinfection for your water. Even if water is not flowing through the pipes, chlorine dioxide prevents germs from building up again thanks to its outstanding sustained-release action. The sterilization process with chlorine dioxide is also taste and odour-free.

Chlorine Dioxide Offers a Wide Range of Other Benefits

As  a bactericide, sporicide , virucide and algicide, chlorine dioxide is in every respect highly effective against all critical and even chlorine resistance germs.

Chlorine dioxide is particularly effective in fighting legionella and prevents biofilm formation and corrosion of water pipeline systems. It removes the nutrient source for these types of hazardous germs, which significantly prologs the duration of the disinfectant effect.

Its disinfection capability very high even in relatively small quantities and is more or less independent of the PH value. Chlorine dioxide can therefore also be used in an alkaline environment with no problem.

The formation of strong-smelling by-production such as trihalogeno methyls (THM), chlorophenols or chloramines that cause irritation to mucous membranes is negligible. This makes chlorine dioxide the disinfectant of choice for processing food and drink.

Disinfection properties : The disinfection effect of chlorine dioxide is very high even if only very small quantities are added.

Generate Your Chlorine Dioxide Directly on Site With Maximum Yield :

Two Methods Have Been Tried And Tested Worldwide And Conform To International Standards

The disinfectant can be generated on site either from chlorine and hydrochloric acid or from chlorite and chlorine. With both these processes, Grundfos Alldos meets the stringent  requirements of DIN EN 12671 for disinfection of drinking water.

The disinfectant yield is up to 95% with both methods. It is used as an aqueous solution containing 0.5 – 3 mg CLO2/I , depending on the application.

1. Hydrochloric Acid / Sodium Chlorite Method :

With the acid dioxide can be generated from diluted or concentrated sodium chlorite and hydrochloric acid solutions depending on the user’s requirements :

Diluted                 : HCL  9%, NaCLO2  7.5%

Concentrate       : HCL  33%, NaCLO2  24.5%

The Chemical Formula :

5 NaCLO2 + 4 HCL  <========è 4 CLO2 + 5 NaCL + 1H2O

1. 2.       Chlorine / Sodium Chlorite Method :

With this particularly cost-effective preparation method, the chemical starting materials are concentrated sodium chlorite solution (24.5%) and chlorine gas ( acidic chlorine solution) dissolved in  water.

The chkorine dioxide is produced according to the chemical formula :

2 NaCLO2 + CL2  <========è 2 CLO2 + 2 NaCL
