FeCl3 36–40% liquid (ferric chloride / iron(III) chloride)
bulk FeCl3 36–40% liquid ferric chloride (CAS 7705-08-0) for industrial WWTP coagulation. COA/MSDS on request. Loc Thien — 0979 891 929.
FeCl₃ 36–40% liquid (ferric chloride / iron(III) chloride solution, CAS 7705-08-0) is a strong iron-based coagulant for industrial wastewater colour and TSS removal, sludge conditioning and selected etching/utility duties. Loc Thien supplies bulk with COA/MSDS on request — hotline 0979 891 929.
FeCl₃ is not the same as FeCl₂ or PAC. Choose by jar test: iron salts often help colour; PAC is aluminium-based. See our FeCl hub and PAC hub, plus the comparison article FeCl₂ vs FeSO₄ vs PAC.
What is liquid FeCl₃ 36–40%?
Ferric chloride solution is a corrosive, acidic iron(III) salt solution used mainly as a coagulant / flocculant aid in water and wastewater treatment. Commercial liquid grades are often marketed around 36–40% as FeCl₃ (confirm each lot on the COA). It forms iron hydroxide flocs that trap suspended solids and can reduce colour in many dye-bearing streams.

FeCl₃ vs FeCl₂ vs PAC — plant view
| Chemical | Base | Often chosen when… | Loc Thien |
|---|---|---|---|
| FeCl₃ | Iron(III) | Colour/TSS removal, strong coagulation, some sludge programs | This page |
| FeCl₂ | Iron(II) | Different valence/chemistry; not a drop-in for every FeCl₃ duty | FeCl₂ |
| PAC | Aluminium | Many potable/industrial trains; different residual metal profile | PAC 31% Viet Tri |
Never swap coagulants 1:1 without a jar test on real wastewater. Dose, pH, polymer pairing and discharge limits differ.
Industrial applications ()
- Industrial WWTP: coagulation for TSS, turbidity and colour (textile, paper, mixed industry parks).
- Sludge / conditioning support: iron chemistry in selected dewatering programs (site-specific).
- Utility / process water: where the process engineer specifies ferric chloride.
- Etching / specialty (controlled): some PCB or metal-treatment recipes use FeCl₃ — only under trained process control, not DIY consumer use on this page.
Handling and safety
- Corrosive acidic liquid — PPE, eyewash, trained operators; store away from incompatible alkalis and metals that react aggressively.
- Dose systems need compatible materials (confirm with your vendor for seals, pumps, tanks).
- Keep MSDS on the floor; spill response per site HSE.
- Coordinate pH correction (often alkali such as NaOH) after coagulation if the train requires it.
- Do not mix chemicals in the same day-tank without engineering approval.
Packing, storage, delivery
Common packs: drums, IBC and bulk enquiry. Store sealed, labeled, secondary containment where required. Loc Thien delivers to factories and KCN nationwide (HCM, Binh Duong, Dong Nai and other parks) — include the delivery point on the RFQ.
FAQ — FeCl₃ 36–40% liquid
What is the CAS number of ferric chloride?
Common reference CAS for FeCl₃ is 7705-08-0. Commercial product is an aqueous solution; concentration is on the lot COA (target band about 36–40%).
How do FeCl₃ and FeCl₂ differ?
FeCl₃ is iron(III) chloride; FeCl₂ is iron(II) chloride. They differ in oxidation state, colour behaviour and process fit. See FeCl₂ product and the FeCl hub for side-by-side plant context.
Can FeCl₃ replace PAC?
Not automatically. PAC is aluminium-based; FeCl₃ is iron-based. Jar-test both if your consultant allows; residual metal, colour, sludge and cost will decide. Compare with PAC 31%.
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 FeCl₃ in Vietnam?
Send estimated tonnage, packing (drum/IBC/bulk), delivery industrial park/province and COA needs. We return a quotation without online checkout.
Where is the FeCl category page?
Iron chlorides FeCl₂ / FeCl₃ hub lists related grades and internal links for buyers comparing coagulants.
