Poly Aluminium Chloride (PAC)

Poly Aluminium Chloride (PAC) | Industrial Chemical Trading and Supply by ChemTech

Product Overview

Poly Aluminium Chloride (PAC) is one of the most effective and widely used coagulants and flocculants in water and wastewater treatment processes.
It is a polymerized compound consisting of hydroxylated aluminium chlorides, which provides much higher coagulation efficiency compared to conventional alum (aluminium sulfate).

PAC has a strong ability to aggregate and precipitate suspended solids, organic matter, heavy metals, phosphates, and color pigments, resulting in improved water clarity and quality.

As a leading chemical trading and supply company, ChemTech provides high-quality Poly Aluminium Chloride in multiple grades — including industrial, potable (drinking water), and wastewater grades — sourced from reliable global manufacturers to ensure consistent performance and product quality.

Physical and Chemical Properties

Industrial Applications of Poly Aluminium Chloride (PAC)

💧 1. Drinking Water and Municipal Wastewater Treatment

PAC is one of the most efficient coagulants for drinking water purification and municipal wastewater treatment.
It effectively removes suspended solids, color, turbidity, bacteria, and heavy metals, producing clean and clear water.
Due to its high efficiency and cost-effectiveness, PAC is widely used as a replacement for alum in water treatment plants.

🏭 2. Industrial Wastewater Treatment

In various industries — such as textiles, steel, petrochemicals, pharmaceuticals, and food processing — PAC plays a critical role in the removal of organic pollutants, color, oil, and colloidal materials.
It is particularly effective in wastewater with high COD and BOD, improving sedimentation and reducing the overall pollutant load in the effluent.

🧴 3. Paper and Pulp Industry

In the paper industry, Poly Aluminium Chloride acts as a charge neutralizer and retention agent, enhancing fiber bonding, paper surface quality, brightness, and strength.
It also improves drainage and water recovery in closed water circuits.

🧪 4. Chemical and Pharmaceutical Industries

PAC is used in chemical and pharmaceutical processes for process water purification, impurity removal, and stabilization of liquid formulations.
It also helps control microbial growth and scaling in industrial cooling systems.

🏗 5. Cooling Towers and Power Plants

Due to its ability to remove suspended solids and stabilize pH, PAC is used in industrial cooling towers and power plant systems to enhance equipment lifespan, efficiency, and reduce maintenance costs.

Key Advantages

• Higher coagulation and flocculation efficiency compared to alum
• Reduced sludge generation and faster sedimentation rate
• Wide operating pH range (effective in acidic to alkaline conditions)
• Applicable for both soft and hard water
• Lower chemical consumption and operational costs
• Improves overall system efficiency in water treatment plants

Safety and Storage Guidelines

• Store in a cool, dry, and well-ventilated area, away from direct sunlight and heat.
• Avoid direct contact with skin and eyes.
• Wear protective gloves and goggles while handling.
• In case of skin contact, rinse thoroughly with water.
• Keep away from flammable materials and strong acids.
