Description

Polyferric Sulfate is an inorganic polymeric coagulant, primarily composed of ferric ions and sulfate groups. This compound is valued for its high efficiency in water purification, offering superior flocculation, rapid sedimentation, and effective removal of contaminants like phosphorus and heavy metals. It is an essential chemical for professionals in municipal water treatment, industrial wastewater management, and paper manufacturing seeking a reliable and cost-effective coagulant solution.

Application

• Municipal Water Treatment: Primary coagulant for drinking water purification, effectively removing turbidity, color, and microorganisms.
• Industrial Wastewater Treatment: Treatment of effluents from textiles, tanneries, and metal plating to precipitate phosphates, heavy metals, and suspended solids.
• Paper & Pulp Industry: Used as a retention aid, drainage aid, and for decolorizing process water.
• Urban & Industrial Sludge Conditioning: Enhances sludge dewatering and reduces sludge volume.
• Phosphorus Removal: Highly effective for chemical phosphorus removal in wastewater to meet stringent environmental discharge limits.
• Oil Field Water Treatment: Clarification of produced water and other oil field brines.

Quality Control

Our Polyferric Sulfate is manufactured under strict process controls to ensure batch-to-batch consistency and performance. Quality is verified against key parameters including iron content, basicity, and pH. A comprehensive Certificate of Analysis (COA) detailing assay and impurity profiles is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy. Store away from strong acids and organic solvents.
