 Properties 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.


Advantages of ClO2
  1. ClO2 Is Safe And Environmentally Friendly Disinfectant Product.
There are many reasons why Chlorine Dioxide is safe and environmentally friendly; the by-products formed when using Chlorine Dioxide are benign. Compare this to chlorinated by-products formed when using Chlorine or Hypochlorite and you can see why so many Pulp and Paper Mills use Chlorine Dioxide. They have virtually eliminated trichloromethanes, chloroacetic acids, chlorinated dioxins and furans from their waste streams, all of which used to pose significant risks in the environment. In its reaction, Chlorine Dioxide oxidizes (removes electrons) other compounds and is itself reduced (gains electrons) to the Chlorite anion (CLO2). Toxicological studies have shown the Chlorine Dioxide and its disinfection by-product, Chlorite, pose no significant risk to human, animal or fish health. Chlorine Dioxide was first introduced for drinking water disinfection in 1944 at the Niagara Falls. Today over 1000 municipal water treatment processes use Chlorine Dioxide.

  1. ClO2 Can Effectively Remove Biofilm.
Many biocides have particular problems in penetrating this biofilm, due to the polysaccharide “glue” that is secreted by the bacteria to hold the biofilm together. Unlike most biocides, chlorine dioxide can effectively penetrate biofilm to provide complete protection. Chlorine dioxide kills viruses by preventing protein formation. ClO2 reacts with peptone, a water-soluble substance that originates from hydrolysis of proteins to amino acids.

  1. Microorganism Can Not Buildup Resistance to ClO2
When the cell wall is penetrated by chlorine dioxide, Organic substances within cells and on the surface of cell membranes react with chlorine dioxide, causing cell metabolism to be disrupted. Chlorine dioxide also reacts directly with amino acids and the RNA in the cell. This reaction is not dependent on reaction time or concentration. Unlike non-oxidizing disinfectants, chlorine dioxide kills microorganisms even when they are inactive. Microorganisms are unable to build up resistance to chlorine dioxide, in practical terms.

  1. ClO2 Can Work In Wide PH
Because chlorine dioxide is a dissolved gas, it does not ionise to form weak acids (as chlorine and bromine do) in aqueous solutions. This allows ClO2 to be effective over a wide pH range from Acidic to Alkaline (4-10).
