What Is Chlorine Dioxide?
Chlorine dioxide (ClO2) is a synthetic, green-yellowish gas with a chlorine-like odor. Its influences on human body can be neglected when the density of dosage is less than 500ppm. It won’t cause any influence to human body including physical biochemical factor and without any allergy to skin. In the matter of fact, the common dosage of ClO2 is much less than 500ppm, the average usage is around dozens ppm. Therefore, CLO2 is globally recognized as the safety nontoxic and green disinfector.
Chlorine dioxide is very different from elementary chlorine, both in its chemical structure and in its behavior. One of the most important qualities of chlorine dioxide is its high water solubility, especially in cold water. Chlorine dioxide does not hydrolyze when it enters water; it remains a dissolved gas in solution. Chlorine dioxide is approximately 10 times more soluble in water than chlorine.
When it comes to chlorine dioxide products (tablet & powder), the tablet or the powder do not contain clo2. The principle is that the material of tablet or powder react when dropped into water and produce clo2, which soluble to water soon.
Is There Free Chlorine In Chlorine Dioxide Products?
No, there is no free Chlorine in CDD 5000/CDL 7500. Although Chlorine Dioxide has the word Chlorine in its name but two chemicals have completely different chemical structures of its revolutionary formula. The additional oxygen atom radically changes the molecule and creates completely different chemical behaviours and by-products. Their differences are as profound as those between hydrogen, the explosive gas, and hydrogen combined with oxygen, which creates di-hydrogen oxide – commonly called water.
Has Chlorine Dioxide Got Approval as Water Treatment Chemicals In the World?
Yes!
How Does Chlorine Dioxide Work as Disinfectant?
ClO2 is an oxidizing biocide. It deactivates micro organisms by attacking and penetrating their cell wall, disrupting the transport of nutrients across the cell wall and inhibiting protein synthesis. Since this action occurs regardless of the metabolic state of the organism, oxidizing biocides are effective against dormant organisms and spores (Giardia Cysts and Poliovirus) also.
Features Of Chlorine Dioxide
§ Effective and full elimination of all known in water common microorganisms, i.e. bacteria (incl. Gardia, legionella), viruses (incl. hepatitis, anthrax), protozoan (incl. Crypto and Giardia), yeast, fungi, algae and cysts.
§ Stronger, effiacious and faster disinfection capacity.
§ 260% more disinfection power compared to chlorine.
§ 10 times more oxidizing power compared to chlorine.
§ Long lasting residual disinfection capacity throughout water systems (up to 72 hours, chlorine only 2-6 hours)
§ Highly soluble in water.
§ Steady bactericidal action within a broad pH bandwith (pH 4-10).
§ Very short contact time.(2-10 minutes).
§ No build-up of resistance by microorganisms.
§ Higher efficiency in the removal of iron and managese compounds.
§ Destroys algae related taste and odor compounds.
§ Extensive kinetic half time.
§ Less sewage load by strong decrease in building of organic halogen combinations, provides THM control.
§ High operational safety.
§ No adverse taste and odour effects in the disinfected water.
§ Bounded chlorine building is strongly suppressed.
§ Does not react with water to form hypochlorous acid.
§ ClO2 does not react with ammonia,ammonium or most organic compounds.
§ Decreases,THM’s,HAA’s,MX and other organic compounds with toxic or carcinogenic properties.
§ Removes biofilm very effectively from pipeline & various system parts.
