The most common methods adopted for water treatment are Chlorination, Oxidation by chemicals and aeration.  Chlorination is the Oldest form of Purification and it is Very Economic. But it is highly Corrosive, is reactive to chemicals, resistent to microbes, unsafe to handle and the important factors are Carcinogenic compounds-THMs. The Oxidation Agents commonly used are Hyderogen Peroxide,Ozone and Chloride Dioxide. While Hydrogen Peroxide and ozone and unstable and not suitable for pipelines. Chlorine Dioxide is compratively stable, but difficult to transport. It is explosive also. Phosphates and Nitrates are slow acting chemicals and not suitable for pipeline.

* Micro₂ is not influenced by  temperature and pH.
        * Micro₂ is an oxidizing biocide ike ozone and Hydrogen Peroxide,

but not a metabolic toxin,
                    * Micro₂kills micro-organisms by disruption of the transport of nutrients                                         across  the cell wall, not by disruption of a metabolic process
                        * Micro₂ can successfully penetrate Biofilm in the piping which protects 

                legionella from most of the disinfectants, while other

         Biocides  can not penetrate  Biofilm and hence disease causing bacteria are protected by

                                         a large extent and they re-grow very rapidly.
   * Micro₂is non-toxic and Non-hazardous liquid and no extra safety for handling is necessary. 
       Only Micro₂  is highly effective against both Gram positive and gram negative bacteria.
       99.9% kill rate within 5 minutes.
