Replacement of primary chlorination with ferrate treatment of drinking water at wastewater treatment plants

Drinking water treatment with ferrate at water treatment plants:

  • Chlorine only on secondary chlorination to preserve water after disinfection

  • reduction of toxic organochlorine compounds by 3-10 times

  • improvement of the ecological situation in the region, including in the Neva basin and the Gulf of Finland

  • reducing the dose of coagulants and flocculants (processing is 7 times less expensive).

Advantages of using ferrate for post-treatment and disinfection of domestic wastewater

Post-treatment of household wastewater with sodium ferrate has been tested in St. Petersburg:

  • meeting the requirements for the number of microorganisms (bacteria, viruses, cysts) in water the Neva and the Gulf of Finland

  • half the price of electrolysis hypochlorite

  • lack of chlorine and its compounds in the drain

  • reduction of toxic mutagenic organochlorine
