Poly Aluminium Chloride (PAC)

Poly Aluminium Chloride (PAC) is a widely used inorganic polymer coagulant for water treatment and wastewater treatment. It is available in different grades and forms to meet the requirements of municipal drinking water treatment, industrial wastewater treatment, sewage treatment, and various water purification processes.

PAC works by destabilizing suspended particles, colloids, and other impurities in water, allowing them to form larger flocs that can be efficiently removed through sedimentation or filtration. Compared with conventional inorganic coagulants, Poly Aluminium Chloride offers effective coagulation performance and is suitable for a wide range of water treatment applications.

Applications of Poly Aluminium Chloride

Drinking Water Treatment

Poly Aluminium Chloride is widely used in drinking water purification processes. It promotes the aggregation of fine suspended particles and colloids, helping improve water clarification and reduce turbidity.

PAC can be used in:

• Drinking water purification
• Raw water treatment
• Surface water treatment
• River water treatment
• Reservoir water treatment
• Water clarification

Industrial Wastewater Treatment

PAC is commonly used as a coagulant in industrial wastewater treatment. It helps remove suspended solids, colloidal substances, and other contaminants before subsequent treatment processes.

Typical applications include:

• Chemical industry wastewater
• Textile wastewater
• Food processing wastewater
• Paper mill wastewater
• Pharmaceutical wastewater
• Electroplating wastewater
• Industrial process water
• General wastewater treatment

Municipal Sewage Treatment

Poly Aluminium Chloride can be used in municipal sewage treatment plants to improve coagulation and flocculation during primary and advanced treatment processes.

It can assist with:

• Suspended solids removal
• Turbidity reduction
• Phosphorus removal
• Sludge conditioning
• Water clarification

How Does Poly Aluminium Chloride Work?

When PAC is added to water, its aluminum-based polymeric species interact with suspended particles and colloids. This reduces particle stability and promotes aggregation.

The resulting flocs can then be separated from the treated water through processes such as:

Coagulation → Flocculation → Sedimentation → Filtration

The optimum PAC dosage depends on the characteristics of the raw water or wastewater. Factors such as turbidity, pH, alkalinity, suspended solids, organic matter, and treatment process should be considered when determining the appropriate dosage.

Poly Aluminium Chloride Grades

Poly Aluminium Chloride can be supplied in different grades depending on the intended application.

PAC for Drinking Water

Drinking water grade PAC is designed for water purification applications and is commonly selected based on aluminum content, basicity, insoluble matter, and applicable regulatory requirements.

PAC for Industrial Water Treatment

Industrial-grade PAC is widely used for wastewater treatment and process water clarification. It can be customized according to the characteristics of different industrial wastewater streams.

PAC for Sewage Treatment

PAC for sewage treatment is commonly used to improve coagulation, suspended solids removal, phosphorus removal, and sludge conditioning.

Specifications can be adjusted according to customer requirements and application conditions.

Advantages of Using PAC in Water Treatment

Poly Aluminium Chloride offers several advantages for coagulation and clarification processes:

High coagulation efficiency
PAC can effectively destabilize suspended particles and colloids, promoting the formation of larger and more easily separable flocs.

Wide application range
PAC is suitable for drinking water treatment, municipal sewage treatment, industrial wastewater treatment, and various process water applications.

Good turbidity removal
It is commonly used to reduce turbidity and improve the clarity of treated water.

Flexible product grades
Different PAC grades can be selected according to raw water characteristics and treatment requirements.

Suitable for automated systems
PAC can be used in both batch and continuous water treatment systems and can be integrated into automated dosing equipment.

Packaging and Storage

Poly Aluminium Chloride powder is normally packed in moisture-resistant bags, such as 25 kg bags, with customized packaging available for bulk orders.

The product should be stored in a dry, cool, and well-ventilated area, away from moisture and incompatible materials. Keep the packaging properly sealed during storage and transportation.

Frequently Asked Questions

What is Poly Aluminium Chloride?

Poly Aluminium Chloride, commonly known as PAC, is an inorganic polymer coagulant widely used in water purification and wastewater treatment.

What is the CAS number of PAC?

The CAS number of Poly Aluminium Chloride is 1327-41-9.

What is Poly Aluminium Chloride used for?

PAC is mainly used for drinking water treatment, municipal sewage treatment, industrial wastewater treatment, turbidity removal, suspended solids removal, phosphorus removal, and water clarification.

Is PAC suitable for wastewater treatment?

Yes. PAC is widely used as a coagulant in industrial and municipal wastewater treatment systems.

What is the difference between PAC and alum?

Both PAC and alum are aluminum-based coagulants. PAC is a pre-polymerized coagulant and can offer effective coagulation across a relatively broad range of water treatment conditions. The most suitable product depends on the specific water quality and treatment process.

How much PAC should be used?

PAC dosage varies according to the raw water or wastewater characteristics. A laboratory jar test is generally recommended to determine the optimum dosage before full-scale application.
