Description

Polyaluminum Chloride (PAC) is an inorganic polymer coagulant widely recognized for its superior performance in water purification and treatment processes. Its high efficiency in removing suspended solids, organic matter, and phosphates makes it a critical component for ensuring water quality and regulatory compliance. This product is essential for industries and municipalities requiring robust, cost-effective solutions for wastewater treatment, potable water production, and process water conditioning.

Application

• Drinking Water Treatment: Primary coagulant for the removal of turbidity, color, and organic contaminants in municipal water plants.
• Industrial & Municipal Wastewater Treatment: Effective for clarifying industrial effluents and sewage, including the precipitation of phosphates and heavy metals.
• Paper Manufacturing: Used as a retention aid, drainage aid, and for wastewater clarification within paper mills.
• Textile Industry: Employed in the treatment of dyeing and finishing wastewater to remove color and chemical oxygen demand (COD).
• Oil Field & Mining Operations: Applied in process water clarification and the treatment of produced water or tailings.
• Swimming Pool & Aquaculture: Acts as a flocculant to maintain water clarity and hygiene.

Quality Control

Our Polyaluminum Chloride is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Production adheres to relevant industry standards for water treatment chemicals. Comprehensive quality testing is performed, including analysis of key parameters such as aluminum oxide (Al2O3) content, basicity, and density. A Certificate of Analysis (COA) is provided with each shipment to guarantee specification compliance.

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 when not in use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy. Store away from incompatible materials such as strong alkalis.
