Description

Ferric Sulfate Nonahydrate is a hydrated inorganic salt of iron, widely recognized for its role as a highly effective coagulant and flocculant in water purification processes. Its primary commercial value lies in its ability to remove suspended solids, organic color, and phosphates from industrial and municipal wastewater, offering a cost-effective and reliable solution for environmental compliance. This product is essential for operators in water treatment, paper manufacturing, and metal surface finishing who require consistent performance and high-purity raw materials.

Application

• Water and Wastewater Treatment: Primary application as a coagulant for removing turbidity, color, and phosphate in drinking water, industrial effluent, and sewage treatment plants.
• Industrial Process Water: Used in cooling towers and boiler feed water systems for conditioning and sludge conditioning.
• Pulp and Paper Industry: Employed in wastewater treatment and as a mordant in dyeing processes.
• Metal Surface Treatment: Acts as an etching agent and in phosphate removal from metal finishing baths.
• Soil Stabilization: Utilized in construction and geotechnical engineering to improve soil strength and reduce permeability.
• Pigment Manufacturing: Serves as a raw material in the production of iron oxide pigments and other iron-based compounds.

Quality Control

Our Ferric Sulfate Nonahydrate is manufactured under a stringent quality management system. Each batch is tested to ensure it meets precise specifications for purity, iron content, and heavy metal limits. A comprehensive Certificate of Analysis (COA) documenting assay, impurity profiles, and physical parameters is provided with every shipment to guarantee traceability and compliance with industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in original packaging or a suitable moisture-proof container to prevent caking and degradation. Keep away from incompatible materials such as strong bases and reducing agents.
