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
