Ferric chloride – 40%, 42%

Ferric Chloride Solution – Available in 40% & 42% Concentrations

Ferric chloride solution is one of those chemicals that shows up in more places than you’d expect — wastewater treatment plants, metal finishing facilities, electronics workshops. It plays a critical role, quietly but reliably. At Pascom, we supply two industry-grade concentrations — 40% and 42% — designed to suit everything from large municipal systems to tightly controlled industrial processes.

And whether you’re managing a city’s treatment infrastructure or running a printed circuit board (PCB) line, these ferric chloride options deliver the kind of consistency you can’t afford to be without. They dissolve fast, react aggressively (in a good way), and last long enough on the shelf to be practical.

What Is Ferric Chloride, Exactly?

Ferric chloride — that’s FeCl₃ if you’re the type to think in formulas — is also called iron(III) chloride. Some folks even refer to it as iron trichloride or iron perchloride. It’s a dark, corrosive liquid, usually brownish, with a kind of faintly metallic, acidic smell. Not pleasant, but unmistakable. The reason it’s so widely used? Its strong oxidising and coagulating properties.

When added to water, ferric chloride reacts fast. It’s acidic, sure, but that’s part of the magic — it latches onto phosphates, organic compounds, and all sorts of suspended solids. The stuff’s hygroscopic, and it actually releases heat when mixed with water. So yeah, handle it with care, maybe even a pair of gloves and an eye on the MSDS.

📊 Concentration Options

🧪 Ferric Chloride 40% Solution

This is the go-to choice for general applications — water treatment, coagulation, phosphorus removal, all that. Most municipalities stick with 40% because it hits that sweet spot between performance and ease of use. You’ll also see it in places managing sludge or odour issues. It’s kind of the workhorse of the two.

Typical properties:

• Appearance: Dark brown liquid
• Odour: Slightly pungent, unmistakable
• Solubility: Fully water-soluble
• pH: Below 2 — so yes, it’s acidic

🧪 Ferric Chloride 42% Solution

This one? A bit stronger. The 42% grade is preferred when you need something more aggressive — think metal surface treatment, dye production, or etching circuit boards with precision. It’s got a little more punch per litre, which is especially helpful when you’re trying to minimise the volume you use without compromising effect.

We’ve noticed that clients in mining and heavy chemical industries tend to lean toward this version. Makes sense — more iron, more reactivity, tighter control.

🏭 Common Applications & Real Benefits

If we had to sum it up, ferric chloride is like a behind-the-scenes specialist. It shows up, does the job — whether that’s binding impurities or etching away copper — and then it’s gone. In wastewater treatment, it’s crucial for bringing down phosphorus levels and clearing out suspended solids. In electronics, it’s essential for stripping copper during PCB fabrication.

But it doesn’t stop there:

• Dye and pigment manufacturing
• Sludge dewatering (especially in high-volume plants)
• Sewer odour control — trust us, you’ll be thankful

It’s not just the versatility that makes it popular — it’s also the economics. Effective, available, and easily dosed in liquid form.
