Key Advantages of HOO CHEMTEC Ferrous Chloride Tetrahydrate
High-Purity & Consistent Quality: Available in 92% and 99% purity grades, ensuring reliable and effective performance for your critical applications.
Effective Environmental Solution: Acts as an effective coagulant and phosphate remover in industrial wastewater treatment, helping to prevent eutrophication in treated effluent.
Versatile Industrial Performer: Serves multiple roles across industries—from a key raw material in chemical synthesis to an eco-friendly agent for stone coloring and metal surface treatment.
Powerful Reducing Agent: Functions as an effective reducing agent (e.g., in Fenton’s process) and for hydrogen sulfide fixation, valuable in chemical catalysis and odor control.
What is Ferrous Chloride Tetrahydrate Used for?
- Drinking Water Purification: It acts as a coagulant to remove suspended solids, phosphates, and impurities, improving water clarity and safety.
- Wastewater Treatment: It effectively removes phosphates to prevent eutrophication and reduces sulfide odors/corrosion in sewage and industrial effluent.
- Chemical Catalysis and Fixation: It serves as a reducing agent in organic reactions (e.g., Fenton process) and chemically fixes toxic hydrogen sulfide gas.
- Stone Coloring Agent: When applied, it oxidizes to form permanent iron oxide pigments, imparting reddish-brown hues to concrete and natural stone.
- Metal Protection: It forms iron phosphate conversion coatings on steel surfaces, enhancing corrosion resistance and paint adhesion.
- Raw Material Preparation: It is a key precursor for synthesizing other iron compounds like ferric chloride, iron oxides, and magnetic ferrites.
FAQ of Ferrous Chloride Tetrahydrate
It is primarily used as a coagulant in water treatment to remove impurities and phosphates. It also serves as a reducing agent in chemical processes, an eco-friendly stone coloring agent, and for metal surface treatment.
When applied, it oxidizes on the stone surface to form stable, natural iron oxide pigments, creating permanent reddish-brown hues in an eco-friendly way.
