There are several “classical” methods of chlorine dioxide production. All these methods have advantages and disadvantages but, in general, their limitations have restricted the widespread use of chlorine dioxide despite its many well-known advantages over conventional methods of water disinfection such as chlorination.
CleanOxide 75 is the modern, simple method of producing practically pure solutions of aqueous chlorine dioxide without the disadvantages of the “classical” methods. The table below highlights the many advantages of CleanOxide 75.
|Chlorine Dioxide||Classical “Chlorine Dioxide”|
|CleanOxide 75 is a pure (99%) solution of chlorine dioxide in water (7500 mg/L). It is stable with a useful life of >30days.||Classically generated chlorine dioxide decays rapidly when the concentration of chlorine dioxide exceeds 0.5%.|
|The purity and consistency of the precursor solutions allows CleanOxide to be consistently produced with a known concentration of chlorine dioxide.||Classically generated chlorine dioxide is diluted as it is produced making it difficult to control the concentration with any certainty.|
|No complex equipment is required to produce CleanOxide 75.||Classically generated chlorine dioxide requires complex and expensive equipment.|
|The precursor solutions are certified and approved to the highest quality standards (including European Regulation EN12671).||Toxic and impure chemical compounds are often used to generate chlorine dioxide by classical methods.|
|The purity of CleanOxide 75 Solution is 99%.||Classical chlorine dioxide solutions are often only 65% pure.|
|CleanOxide 75 can be generated on site or supplied ready mixed. Provided the recommended storage conditions are observed, the solution has a useful life of greater than 30 days.||Classical chlorine dioxide must be generated on site and used immediately. Typically it has a half life of only a few hours.|
|CleanOxide 75 is a 0.7 5% solution of pure chlorine dioxide in water. The only impurities are sodium sulphate, a small amount of sodium chloride and less than 75mg/ L sodium chlorite.||Classical chloride dioxide solution contains high levels of chlorite, chlorate, chloride and free chlorine.|
|CleanOxide 75 does NOT contain free chlorine.||Classical chloride dioxide contains free chlorine and therefore has many of the disadvantages associated with chlorination of water.|
|CleanOxide 75 is not corrosive when dosed at the recommended rates.||Classical chloride dioxide is very corrosive.|
|CleanOxide 75 does not adversely affect reverse osmosis membranes, ion exchange media or active carbon beds. It can be used to control biofouling in these situations.||Classical chlorine dioxide damages reverse osmosis membranes, ion exchange media and active carbon beds. It cannot be used to control biofouling in these situations.|
