Sodium ferrate Na₂FeO₄ — the most powerful water oxidiser you can produce at the point of use
The technology the Dobrokhim team has been developing since 2020. The outcome is the Ferrator industrial plant, which produces ferrate electrochemically from NaOH and a steel electrode.
Three reagent classes in a single molecule
One sodium-ferrate molecule does the work that normally takes three separate process stages.
Organic oxidation
R-H + FeO₄²⁻ → R-OH + Fe(OH)₃Ferrates oxidise a wide range of organic compounds — petroleum products, phenols, pharmaceuticals and surfactants.
Suspended-solids coagulation
Fe(OH)₃ ↓ → suspension aggregates, metals boundAs the ferrate decomposes it produces an active iron hydroxide that binds heavy metals and phosphates.
Disinfection
FeO₄²⁻ + microorganisms → full inactivationFerrates kill bacteria, viruses, cysts and spores without generating toxic chloro-organics.
+2.2 V — higher than any industrial oxidiser
The higher the redox potential, the faster and more complete the oxidation. Sodium ferrate beats ozone and permanganate.
