Flocculants

Product Overview

Solid Ferric Chloride (FeCl₃), also known as Anhydrous Iron(III) Chloride, is a high-performance inorganic chemical widely used in water treatment, wastewater purification, chemical synthesis, catalyst production, electronics etching, and many specialized industrial areas. Compared with liquid ferric chloride, the powder form offers several advantages including higher purity, higher Fe³⁺ activity, reduced transportation cost, easier storage, and zero risk of crystallization during cold seasons.

We supplies high-purity solid Ferric Chloride (96%–98%), produced under strict quality control to ensure purity, stability and excellent performance in both water treatment and industrial applications.

Key Applications

1. Water & Wastewater Treatment

Ferric chloride powder is an excellent coagulant and flocculant used for clarification and purification in:

• drinking water treatment
• municipal wastewater treatment plants
• industrial effluent treatment
• oily wastewater
• dyeing, plating and mining wastewater

When dissolved in water, FeCl₃ hydrolyzes to form Fe(OH)₃ flocs, which effectively:

• destabilize colloidal impurities
• remove turbidity
• reduce suspended solids (TSS)
• bind dissolved organic matter
• reduce color & COD
• remove phosphorus (P-PO₄³⁻)
• precipitate heavy metals

Ferric chloride powder is especially favored in regions requiring low sludge volume, strong coagulation force, and high purity water outlet quality.

2. Phosphorus Removal (De-phosphorization)

In wastewater containing high phosphorus concentrations, solid FeCl₃ reacts with phosphate ions to form insoluble Ferric Phosphate, enabling:

• efficient phosphorus removal

• prevention of eutrophication

• compliance with strict environmental discharge limits

Solid FeCl₃ is widely used in sewage plants, fertilizer factories, food processing wastewater, and livestock farms.

3. Electronics & PCB Etching

Ferric chloride powder is one of the most widely used etchants for printed circuit boards (PCB) and metal surfaces.

Applications include:

• copper PCB etching solution preparation
• stainless steel, alloy and iron surface etching
• micro-etching for precision manufacturing

Solid form ensures:

• easier preparation of high-concentration etchant
• lower impurities
• stronger etching ability
• stable etching speed

Many electronics manufacturers prefer solid FeCl₃ because it provides cleaner etching lines and more precise circuit patterns.

4. Catalyst & Chemical Synthesis

Solid Ferric Chloride is a key raw material or catalyst in:

• Friedel–Crafts reactions
• organic synthesis
• polymerization catalysts
• pharmaceutical intermediates production
• dye and pigment manufacturing
• petrochemical processes
• chlorination reactions

The high Fe³⁺ activity of anhydrous ferric chloride makes it ideal for high-value chemical production.

5. Pigments, Printing & Surface Treatment

Other common uses include:

• pigment and ink industry
• surface treatment of metals
• leather processing
• sewage odor control
• sludge conditioning

Because the solid form is highly concentrated, it gives better economy and performance in these applications.

Product Advantages (Why Choose WaterCareChem FeCl₃ Solid?)

✔ High Purity (96–98%)

Ensures excellent reaction efficiency and high Fe³⁺ performance.

✔ Stronger Coagulation than Liquid FeCl₃

Because the product is anhydrous, every kilogram delivers higher active iron content vs. 40% liquid solutions.

✔ Cost-Efficient Transportation & Storage

No need for heavy drums or tanks; powder reduces logistics costs significantly.

✔ Stable & Long Shelf Life

Less prone to crystallization compared to liquid ferric chloride in cold climates.

✔ Versatile Application

Suitable for water treatment, etching, catalysis, chemical synthesis, and industrial processes.

✔ Custom Packaging

• 50 kg iron drum
• Customized packaging upon request

How to Use (Guidelines)

Dissolving Method:
Add the required amount of solid ferric chloride into a mixing tank and slowly dissolve in clean water under stirring.
Typical dosing concentrations: 10%–40% solution depending on application.
