Poly Aluminium Chloride

About Poly Aluminium Chloride

Poly Aluminium Chloride (PAC) is a highly effective inorganic polymer coagulant widely used in water and wastewater treatment. It is a pre-hydrolyzed aluminum-based chemical that helps remove suspended particles, turbidity, color, organic matter, and certain dissolved contaminants from water.

Chemical Information

• Chemical Name: Poly Aluminium Chloride
• Abbreviation: PAC
• Chemical Formula: Commonly represented as Al(OH)Cl
• Appearance: Yellow powder, light-yellow powder, or brown liquid/powder depending on grade and purity
• Solubility: Readily soluble in water

Key Properties

• High coagulation efficiency
• Effective over a wide pH range
• Produces less sludge compared to traditional coagulants such as Alum
• Rapid floc formation and settling
• Lower dosage requirements in many applications
• Improved water clarity and filtration performance

Applications

1. Drinking Water Treatment
   • Removal of turbidity, suspended solids, and microorganisms.
2. Municipal Wastewater Treatment
   • Clarification of sewage and reduction of pollutants.
3. Industrial Wastewater Treatment
   • Treatment of effluents from textile, paper, chemical, food-processing, and metal-finishing industries.
4. Paper Industry
   • Used as a retention aid and sizing agent.
5. Other Uses
   • Swimming pool water treatment
   • Mining and mineral processing
   • Oil and gas wastewater treatment

Advantages

• Faster settling of impurities
• Reduced chemical consumption
• Lower operating costs
• Better performance at low temperatures
• Less impact on treated water pH

Typical Storage

• Store in a cool, dry, and well-ventilated area.
• Protect from moisture and direct sunlight.
• Keep containers tightly closed when not in use.

Sample Technical Description

Poly Aluminium Chloride (PAC) is an advanced inorganic polymer coagulant used for the purification of drinking water, industrial process water, and wastewater. It provides excellent coagulation and flocculation performance, resulting in efficient removal of suspended solids, turbidity, color, and organic contaminants. PAC offers rapid settling characteristics, reduced sludge generation, and effective treatment across a broad pH range, making it a preferred choice for modern water treatment applications.
