Chlorine Dioxide, the science behind

The features

While monochloramine is the best choice for building water system, some process applications require a stronger and faster disinfectant.

This is the reason why Sanipur developed SaniSWEEP: the chlorine dioxide generator.

Chlorine dioxide as an oxidant

Chlorine dioxide is an extremely effective disinfectant and bactericide, equal or superior to chlorine on a mass dosage basis.

It is used as both a disinfectant and an oxidant in drinking water treatment. It has several distinct chemical advantages, which complement the traditional use of chlorine in potable water treatment.

It has two different features:

  • Non-formation of chlorinated compounds;
  • Having a persistent action to cover disinfection in distribution networks.

Features:

  • Greenish-yellow gas with a pungent smell
  • Relatively little soluble
  • High disinfecting power
  • Speed of action
  • It does not form chloramines
  • Influence from pH

The greatest limitation of the chlorine is that there are currently no stable solutions of this reagent, which must be prepared and used immediately after, to avoid degradation. Sanipur found a solution with SaniSweep, that dose chlorine in situ at the correct ppm.

Main applications

The most common applications are those related to its high oxidation reactivity, its superior bactericidal power and its reaction capacity with limited formation of by-products, if used correctly.

SaniSWEEP units generate chlorine dioxide starting from stable diluted acid and sodium chlorite solutions.

Thanks to SaniSWEEP the dosage of the dioxide will no longer be a problem. SaniSweep is the technology that allows the use of chlorine dioxide with maximum safety.
