Description

Polyaluminum Chloride Hydroxide Sulfate is an inorganic polymer coagulant, a high-performance variant of polyaluminum chloride (PAC). This compound is engineered for superior flocculation efficiency, offering rapid settling and effective turbidity removal across a wide pH range. It is a critical raw material for industrial water treatment, municipal wastewater purification, and paper manufacturing processes where high-performance clarification is required.

Application

• Drinking Water & Municipal Wastewater Treatment: Primary coagulant for removing suspended solids, organic matter, and phosphates.
• Industrial Process Water & Effluent Treatment: Used in power plants, refineries, and chemical plants for clarifying process water and treating industrial wastewater.
• Paper & Pulp Industry: Acts as a retention aid, drainage aid, and flocculant to improve paper quality and mill water recycling.
• Textile Dyeing & Printing Wastewater: Effectively removes colorants and chemical oxygen demand (COD) from complex dye baths.
• Oilfield & Mining Operations: Clarifies produced water and aids in the separation of solids in mineral processing.
• Swimming Pool & Aquaculture Water Management: Helps maintain water clarity by removing fine particulates.

Quality Control

Our Polyaluminum Chloride Hydroxide Sulfate is manufactured under a stringent quality management system. Each batch is tested to ensure consistent performance in key parameters such as aluminum oxide (Al2O3) content, basicity, and sulfate concentration. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent caking and maintain efficacy. Keep away from strong acids and organic solvents.
