Ferric Chloride Liquid (FeCl₃) is an industrial aqueous solution widely utilized as a premier inorganic coagulant and etching chemical. Serving critical applications in municipal water treatment, industrial wastewater clarification, electronics circuit board etching, and odor control.
Ferric Chloride Liquid is a stabilized, concentrated aqueous solution of iron(III) chloride designed for immediate automated dosing without the need for dissolving equipment. It functions as a rapid, heavy-floc coagulant that performs effectively across a wide pH range (4.0 to 11.0).
In addition to municipal sewage treatment and industrial effluent clarification, Glossy Ferric Chloride Liquid is widely supplied to the electronics and semiconductor industry for precision copper track etching on printed circuit boards (PCBs) and stainless steel photo-chemical machining.
Heavy-floc coagulant for municipal drinking water, sewage treatment plants, and heavy metal removal.
Precipitates orthophosphates and polyphosphates in wastewater to comply with environmental discharge limits.
Ready-to-use liquid etchant providing uniform, high etch rate with fine line definition on copper clad laminates.
Precision etching of stainless steel, brass, bronze, decorative metal signs, and printing plates.
Improves filter press yield and reduces moisture content in municipal and industrial sludge cakes.
