What Is Ferric Chloride?
Ferric Chloride, also known as Iron(III) Chloride or FeCl₃, is an inorganic iron salt widely used in water treatment, wastewater treatment and industrial chemical processes.
Ferric Chloride has strong chemical reactivity and can act as an effective coagulant in water treatment. It reacts with water to form hydrolyzed iron species and iron hydroxide precipitates, which help destabilize suspended particles and facilitate their removal.
Depending on the application, Ferric Chloride can be supplied in anhydrous solid form or as an aqueous solution.

| Feature | Ferric Chloride Anhydrous | Ferric Chloride Solution |
| Value Proposition | The Freight-Saving Powerhouse | Ready-to-Use & Hassle-Free |
| Purity / Concentration | 98% Active Content | 38% – 42% Stable Concentration |
| Physical Form | Black-brown Crystalline Powder | Red-brown Transparent Liquid |
| Operational Handling | Requires dissolving; exothermic (heat-releasing) reaction; dust control needed. | Plug-and-play; compatible with automated dosing pumps; no dust or heat risks. |
| Etching Precision | Requires manual dilution; ideal for bulk or industrial etching. | High-precision consistency; protects expensive equipment; ensures sharp edges. |
| Logistics Advantage | High: Lowest shipping cost per active unit (Best for trans-oceanic trade). | Moderate: Higher freight due to water weight (Best for regional/local supply). |
| Storage & Safety | Must be kept moisture-free to prevent liquefaction; highly corrosive. | Easier handling in closed-loop systems; enhanced operator safety. |
| Best Application | Long-distance importers, organic synthesis (catalyst), dye industry. | PCB manufacturing, municipal wastewater plants, precision metal etching. |
What is Ferric Chloride Used for?
- Water & Wastewater Treatment – Coagulation, phosphorus removal, suspended solids and turbidity reduction.
- Industrial Wastewater – Treatment of municipal, chemical, textile and other industrial effluents.
- Metal Treatment & PCB Etching – Used as an etching and surface-treatment chemical.
- Chemical Processing – Used as a raw material or reagent in various industrial processes.
Ferric Chloride vs Other Coagulants

| PAC | Aluminum-based coagulant | Water & wastewater |
| PAFC | Aluminum-iron coagulant | Complex wastewater |
FAQ of Ferric Chloride
Yes. Ferric salts can react with phosphate and help remove phosphorus during wastewater treatment.
Anhydrous (96% min) offers higher concentration and faster reaction speeds. Its solid form significantly reduces transportation and storage costs, eliminates leakage risks, and provides a longer shelf life compared to liquid solutions.
It acts as a coagulant. When added to water, it hydrolyzes into ferric hydroxide flocs that trap and settle impurities. It is particularly effective for sludge dewatering and removing odors/color from industrial effluent.
Yes, it is classified as a corrosive substance (UN 1773). It must be stored in a cool, dry place in moisture-proof packaging (like Hoochemtec’s 50kg drums) and handled with proper PPE to prevent skin and metal corrosion.
Yes. HOO CHEMTEC supports bulk B2B orders with export packaging and documentation.

Ferric Chloride is corrosive and should be handled and stored according to the applicable SDS.
It should be stored in a cool, well-ventilated warehouse and should not be piled up in the open. Do not store or transport it with toxic substances.
