Sodium ferrate rewrites the rules of industrial water treatment

Ferrator produces sodium ferrate right at your facility. A single reagent oxidises contaminants, precipitates heavy metals and disinfects water — with no toxic chloro-organics and no residual chlorine. Reagent spend drops by up to 70%.

More than 20 plants and sites across several sectors have run pilot trials.

Technological sovereignty

Made in Russia. Independent from imported supplies

Ferrator and its consumables are produced in Russia. There is no dependency on imported supplies or the regulatory risk that comes with them. The equipment meets domestic import- substitution requirements.

“Made in Russia” programme mark

Saint Petersburg. Assembly, commissioning and service handled by our in-house engineering centre.

44-FZ and 223-FZ compliance

Compatible with Russian public and corporate procurement procedures. Full documentation pack provided.

Skolkovo resident since 2021

Russian patent No. 2840323. Skolkovo and FASIE grants confirm the scientific depth of the technology.

Domestic consumables

NaOH alkali and steel electrode sourced from Russian suppliers. No exposure to imported supply chains.

The industry problem

Why 55% of Russian industrial sites pay fines for their wastewater

RUB 273.84 billion — total environmental fines for 2023 (Rosstat). Sanitary regulations keep tightening, yet cost-effective treatment technologies for small- and mid-scale volumes are still missing.

Chlorine is being phased out

A full ban on residual chlorine in effluent is coming. The alternatives are more expensive and harder to operate.

Ozone and UV — costly and unreliable

Ozone generators consume up to 15 kWh/kg and UV lamps lose efficiency in turbid water. Both demand highly-qualified operators.

Reagents are dosed blind

Lab results arrive up to two weeks late. The result: chemical overuse or non-compliant discharge.

Small volumes have no solutions

For 10–1,000 m³/day the market offers no economically viable turnkey plants.

Technology

Sodium ferrate — one reagent replaces three treatment stages

Sodium ferrate (Na₂FeO₄) is the most powerful known water oxidant, with a redox potential of +2.2 V. A single molecule does the work of three reagent classes: it destroys contaminants, binds suspended solids and kills pathogens. It is produced on site — no hazardous-goods logistics.

Stage 1

Oxidant (+2.2 V)

Destroys organics, petroleum products, phenols, surfactants, pharmaceuticals and pesticides. More effective than ozone or hypochlorite.

Stage 2

Coagulant / flocculant

On decomposition it forms Fe(OH)₃ nanoparticles that capture suspended solids, heavy metals, phosphates and arsenic.

Stage 3

Disinfectant

Kills bacteria, viruses, cysts and spores. Unlike chlorine, it produces no toxic chloro-organic by-products.

After reacting, sodium ferrate turns into iron(III) hydroxide — a naturally occurring mineral. The hazard-class V sludge is disposed of by standard means, without requiring hazardous-waste handling licences.

Key advantages

10 reasons Ferrator rewrites the economics of water treatment

Each of these properties comes from the electrochemical nature of sodium ferrate. Together they make Ferrator the only reagent that simultaneously handles treatment, disinfection and environmental safety.

01

On-site production

Ferrator generates sodium ferrate right at the facility. No hazardous-goods logistics and no reagent storage.

02

Three functions in one

Oxidation + coagulation + disinfection. Replaces several treatment stages with a single reagent.

03

Reagent consumption 2–10× lower

Compared with chlorine, ozone and permanganate — at comparable or higher treatment performance.

04

No toxic by-products

Decomposes to Fe(OH)₃. No disinfection by-products, toxic chloro-organics, haloacetic acids or other carcinogens.

05

Removes heavy metals

Cd, Pb, As, Hg, Cr and other metals are captured by Fe(OH)₃ nanoparticles during coagulation.

06

Treats oily water

Petroleum products, phenols, surfactants and BOD/COD — efficient oxidation of organics in produced and waste water.

07

Works in cold water below 5 °C

The only reagent method that retains its efficiency in the Russian Arctic zone.

08

Integrates into existing infrastructure

A compact stand-alone module. No rebuild of the treatment plant and no long investment cycles.

09

0% residual chlorine in effluent

Full compliance with sanitary regulations. No restrictions on discharge or water reuse.

10

Up to 10× cheaper than legacy methods

On total cost of ownership: CAPEX + OPEX + disposal + fines.

Economic impact

Savings you can measure: real numbers from our deployments

Ferrator pays off in 6–18 months by cutting spend on reagents, power and fines.
