30 October 2026 – Market Krystal has published its Ferrous Chloride market report, covering demand, supply, the value chain and market size, with a forecast for 2026–2035 and scenarios to 2047.
Ferrous chloride is an iron(II) salt sold mostly as an aqueous solution for wastewater treatment, where it precipitates sulfide in sewers and anaerobic digesters and binds phosphate. Most supply is recovered from spent hydrochloric acid pickle liquor at steel finishing lines. Availability therefore depends on steel pickling activity and on whether mills regenerate their acid or sell the iron-rich liquor.
Key findings
Conversion to ferric chloride and municipal wastewater treatment lead demand; North America and Europe are the largest regions.
Steel picklers and acid recyclers such as NLMK, Phibro-Tech, Kemira and PVS supply most volume from spent pickle liquor.
Spent hydrochloric acid pickle liquor + Hydrochloric acid + Scrap iron → ferrous chloride → Feedstock for ferric chloride production, Municipal wastewater phosphate removal and coagulation, Sewer sulfide and odour control
THE QUESTION THE REPORT ANSWERSHow large is the water- and biogas-treatment market for ferrous chloride, and will pickle-liquor supply keep pace as digester H2S control and phosphorus limits tighten?
