How Ferric Chloride Anhydrous Is Used in Water Treatment: Practical Application Guide

Ferric Chloride Anhydrous (无水氯化铁) is one of the most widely specified industrial water plant treatment chemicals used across municipal and industrial facilities. As a iron(III) chloride, it delivers reliable performance in the scenarios our customers ask about most: Waste water treatment, metal etching, dyeing and printing industry.

What Ferric Chloride Anhydrous Is and How It Works

Ferric Chloride Anhydrous is supplied as Black crystalline powder. Its molecular formula is FeCl3 (CAS 7705-08-0). Because of this physical form it dissolves and disperses predictably, which makes dosing and process control straightforward for plant operators.

Primary Applications

Its key application areas include: Waste water treatment, metal etching, dyeing and printing industry. In practice this means iron(III) chloride is selected for both routine maintenance and shock-treatment programs, depending on the water matrix and treatment goal.

• Process reliability: stable active content and consistent granule/tablet size improve dosing accuracy.
• Compatibility: works within existing dosing and storage setups common to industrial water plant treatment chemicals programs.
• Logistics: available in 25/50kg PP bag, simplifying import and warehouse planning.

Why Buyers Choose This Grade

When specifying Ferric Chloride Anhydrous, buyers typically compare active content, packaging and the applicable standard (GB/T1621-2023). Selecting the right grade reduces consumption and protects downstream equipment.

Operators who also run complementary programs often pair this product with Polyacrylamide (PAM) to cover the full treatment chain from clarification to disinfection.
