Chlorine Dioxide

What is Chlorine Dioxide?

Chlorine dioxide (ClO2) is a yellowish gas formed by two oxygen atoms and one chlorine atom. This chemical compound forms an effective disinfectant when dissolves in water used for a variety of antimicrobial uses including water and wastewater disinfection. Chlorine Dioxide destroys bacteria, viruses, fungi, spores, algae, and many different pathogens that make cause sicknesses, such as Cryptosporidium parvum and Giardia lamblia.

Like Chlorine, Chlorine Dioxide is an oxidizing agent (electron receiver). However, Chlorine Dioxide can absorb five electrons whereas chlorine has the capacity to only take in two, which means that ClO2 is 2.6 times more effective than chlorine.

Chlorine Dioxide behavior as an oxidizing agent is quite dissimilar. Like ozone, the predominant oxidation reaction mechanism for chlorine dioxide proceeds through a process known as free radical electrophilic (i.e. electron-attracting) abstraction rather than by oxidative substitution or addition (as in chlorinating agents such as chlorine or hypochlorite). This means that chlorinated organic compounds such as THMs and HAAs are not produced as a result of disinfection using chlorine dioxide.

General Information

  • Very low investment cost for dosing, no reactor required
  • Low operating cost, no need for skilled labor
  • The product is one hundred percent soluble, does not generate waste in the application
  • It is an oxidant at least three times more powerful than chlorine
  • Low corrosivity, no free chlorine
  • The solution has neutral pH (~6.0), so it does not change the pH of the medium
  • Once mixed, the solution has a service life of several days under proper storage conditions
  • Powder components have a service life up to five year
  • Must be diluted in water before application


Chlorine Dioxide is a very good alternative to general disinfectants and also a great alternative to chlorine disinfectants, which according to international research produce carcinogens by-products or cause immunity in pathogenic microorganisms. It has industrial (edible and non-edible products), public and private health, medical and hospital, agriculture, livestock and fisheries, swimming pools, bioterrorism applications. ClO2 also is environment friendly with high shelf life and consequently, its transportation and warehousing is easier compared to other disinfectants. ​

Other Applications

Drinking water treatment centers

Industrial water treatment

Paper and cardboard factories

Poultry farming

Drinking water treatment, cleaning, and disinfection of drinking water distribution systems, disinfection of vents and coolers, disinfection of bathwater, disinfection of hands, disinfection of water tankers, disinfection of surfaces and equipment, disinfection of boots, disinfection of devices. Biofilm causes health and economic damage to poultry farmers, which causes permanent contamination of drinking water due to the entry of microbes and their toxins. Biofilm also reduces the effectiveness of drinking vaccines, water pipes clog, and poses a risk of poisoning due to drug interactions with the herd.

Meat and poultry industry processing industries

Washing live chicken transport cages, disinfection of poultry cages, disinfection of slaughterhouse equipment, disinfection of live chicken carrier truck, washing cages, increasing the shelf life of the meat in pre-cooler


Using in the ice used in breweries, transportation, aquatic animals sales and storage centers, aquaculture facilities and related devices and equipment, control and reduction of biological effects of fishery wastewater.

Gas and oil (petrochemical)

Cleaning pipelines and tanks, iron and manganese separation, wastewater treatment, microbiological control of oil wells, control of THMs compounds, oxidation of sulfide compounds, amino and mercaptan derivatives, hydrogen sulfide gas control, Phenolic, and H2S compounds elimination٬ smell control and elimination of bacteria in the petrochemical production environment

Maritime Fleet


Decolorizing fabric and fibers

Beverages and foodstuffs

Control of THMs compounds, taste and microbiological control

Hotels and Hospitals

Disinfection of work clothes and shoes, washing and disinfection of patients’ utensils and dishes, treatment of drinking water in hospitals, washing corpses, washing ground, and disinfection of equipment.

Pools and aquariums

Growing flowers and greenhouse products


Hoof washing and disinfection pond, temporary storage of colostrum, disinfection of surfaces and floors in milking parlors and maternity wards, disinfection of wounds, disinfection of surgical equipment
