Neutralising acid effluent from titanium-magnesium and non-ferrous plants — heavy metals brought below regulatory limits
A single process replaces a whole rack of reagents and removes the risk of environmental-authority fines.
Key pain points: metallurgy & chemicals
What keeps you from compliance and cost cuts
High Cd, Pb and As concentrations
Conventional Al/Fe coagulants can’t cut heavy metals deeply enough, especially in mixed effluent streams.
pH 1–3 acidity
Multi-stage neutralisation is slow and expensive, and compliance slips during peak discharge hours.
Mixed effluent with variable composition
A single treatment line can’t handle a shifting matrix of organics, metals, surfactants and solvent traces.
Fines for exceeding discharge limits
Environmental regulators carry out inspections 2–4 times a year. Any slip means multi-million-rouble penalties and a production halt.
The technology applied to your industry
The ferrate process combines oxidation and coagulation, producing nano-sized Fe(OH)₃ flocs that bind heavy metals and organic toxicants effectively.
- Cd reduced 2,000×, Pb reduced 100×
- Handles pH 1–3 with no extra neutralisation — the reagent shifts pH itself
- Compatible with existing clarifiers and filter-presses
- Fe(OH)₃ sludge disposed of as Class V (lowest-hazard) waste
Titanium-magnesium plant
At a titanium-magnesium plant we developed a ferrate protocol for mixed acid effluent. Cadmium and lead concentrations were brought to levels consistent with municipal-waterway limits. Sludge is disposed of through the existing scheme.
