FeCl2 15–30% liquid (ferrous chloride / iron(II) chloride)
bulk FeCl2 15–30% liquid ferrous chloride (CAS 7758-94-3) for industrial water programs. COA/MSDS on request. Loc Thien — 0979 891 929.
FeCl₂ 15–30% liquid (ferrous chloride / iron(II) chloride solution, CAS 7758-94-3) is an iron-based coagulant grade for selected industrial water and wastewater programs. Loc Thien supplies bulk with COA/MSDS on request — hotline 0979 891 929.
FeCl₂ is not a drop-in for FeCl₃ or PAC. Iron(II) vs iron(III) vs aluminium chemistry differ in colour response, pH window and sludge. Jar-test on real water; see FeCl₃ 36–40%, PAC 31% and the FeCl hub.
What is liquid FeCl₂ 15–30%?
Ferrous chloride solution is an aqueous iron(II) salt used in industrial coagulation and related utility duties when the process engineer specifies Fe(II) chemistry. Commercial liquid grades are often offered in a 15–30% band — lot COA is the source of truth for assay and density.

FeCl₂ vs FeCl₃ vs PAC — plant view
| Chemical | Base | Often chosen when… | Loc Thien |
|---|---|---|---|
| FeCl₂ | Iron(II) | Process specifies ferrous chloride / Fe(II) program | This page |
| FeCl₃ | Iron(III) | Strong ferric coagulation, many colour/TSS trains | FeCl₃ 36–40% |
| PAC | Aluminium | Al-based coagulation; different residual metal profile | PAC 31% · PAC 10% liquid |
Never swap 1:1 without a jar test. Also see FeCl₂ vs FeSO₄ vs PAC for buyer-oriented comparison context.
Industrial applications ()
- Industrial WWTP: iron-based coagulation where FeCl₂ is specified in the chemical program.
- Colour / TSS support: site-specific; many plants trial FeCl₃ or PAC in parallel.
- Utility trains: only under process engineering control — not a consumer DIY chemical page.
Handling and safety
- Corrosive acidic iron solution — PPE, eyewash, trained operators.
- Use compatible tanks, pumps and seals; secondary containment where required.
- Keep MSDS on the floor; spill response per site HSE.
- Coordinate pH correction (often alkali such as NaOH) when the train requires it after coagulation.
- Do not blend unrelated chemicals in the same day-tank without engineering approval.
Packing, storage, delivery
Common packs: drums, IBC and bulk enquiry. Store sealed and labeled. Loc Thien delivers to factories and KCN nationwide (HCM, Binh Duong, Dong Nai and other parks) — include the delivery point on the RFQ for freight and lead time.
FAQ — FeCl₂ 15–30% liquid
What is the CAS number of ferrous chloride?
Common reference CAS for FeCl₂ is 7758-94-3. Commercial product is an aqueous solution; concentration is on the lot COA (target band about 15–30%).
How do FeCl₂ and FeCl₃ differ?
FeCl₂ is iron(II) chloride; FeCl₃ is iron(III) chloride. They differ in oxidation state and process fit. See FeCl₃ product — do not assume equal doses.
Can FeCl₂ replace PAC?
Not automatically. PAC is aluminium-based; FeCl₂ is iron(II)-based. Jar-test if your consultant allows; residual metal, colour, sludge and cost will decide.
Which FeCl₂ concentrations are available?
Industrial liquid is commonly discussed in a 15–30% window. Confirm the exact assay on COA for the lot you receive.
Can I get COA and MSDS?
Yes. Lot COA and MSDS are provided on request for shipments.
Do you sell retail small bottles with list prices online?
No public retail cart or list price. Loc Thien quotes bulk by volume, packing and delivery point. Hotline 0979 891 929 or request a quote.
How do I order bulk FeCl₂ in Vietnam?
Send estimated tonnage, packing (drum/IBC/bulk), delivery industrial park/province and COA needs. We return a quotation without online checkout.
