Product overview

Ferric chloride is an iron(III) salt that hydrolyzes in water to form dense, fast-settling flocs, making it an effective coagulant across a broad pH range.

It is used in municipal and industrial wastewater treatment, phosphorus removal, sludge conditioning and drinking water clarification, and for etching copper in printed circuit board and metal processing.

Applications

Typical uses for this chemical. Suitability for a specific process, and grade requirements for food, pharmaceutical or potable-water use, should be confirmed with our team.
