Ferric Chloride 40% Solution – Potent Coagulant & Etchant for Water Treatment & Electronics
We supply concentrated Ferric Chloride Solution with a 40% FeCl₃ content. This powerful iron-based coagulant and etching agent is valued for its strong oxidizing and coagulating properties. Consequently, industries actively use it for municipal and industrial wastewater treatment and as a primary etchant for printed circuit boards (PCBs). Moreover, its effectiveness in phosphorus removal, sludge conditioning, and metal surface treatment makes it a versatile and essential industrial chemical.
Core Applications for Ferric Chloride 40% in Industry
This dual-purpose chemical serves critical roles in environmental management and high-tech manufacturing. Its functions are distinct yet equally important for modern infrastructure.
First, the water and wastewater treatment sector relies on ferric chloride 40% as a high-performance coagulant for phosphate removal, odor control, and sludge dewatering. It effectively clarifies water by precipitating contaminants. Therefore, treatment plants depend on it to meet stringent environmental discharge regulations, particularly for phosphorus limits.
Second, the electronics manufacturing industry utilizes it as the standard chemical etchant for copper-clad laminates in PCB production. It precisely removes unwanted copper to create circuit pathways. Furthermore, it is used in metal surface treatment, as a catalyst in chemical synthesis, and in drinking water treatment at controlled doses.
