Poly Aluminium Chloride for Water Treatment

Poly Aluminium Chloride (PAC) for Water Treatment

Poly Aluminium Chloride (PAC) is an inorganic polymer coagulant widely used in drinking water treatment, municipal wastewater treatment, and industrial water purification. It helps treatment systems remove suspended solids, colloidal particles, turbidity, and other impurities by promoting coagulation and floc formation.

BRF SA Chemicals supplies Poly Aluminium Chloride for water treatment to municipal treatment facilities, industrial water processors, mining companies, wastewater treatment operators, and chemical distributors.

Our PAC is available for bulk commercial supply with technical and export documentation.

Minimum Order Quantity (MOQ): 2 MT

What Is Poly Aluminium Chloride in Water Treatment?

Poly Aluminium Chloride, commonly called PAC, is a pre-hydrolyzed aluminium-based coagulant used during the coagulation and clarification stages of water treatment.

Untreated water can contain extremely small suspended and colloidal particles. Many of these particles carry electrical charges that prevent them from joining together and settling naturally.

When PAC is added to water, positively charged aluminium species help destabilize these particles. The destabilized particles then aggregate into larger flocs that treatment systems can remove through sedimentation, flotation, or filtration.

Therefore, the main role of Poly Aluminium Chloride in water treatment is to improve the removal of suspended and colloidal impurities from water.

How Does PAC Work in Water Treatment?

Poly Aluminium Chloride works primarily through coagulation.

The treatment process generally involves several stages.

1. PAC Dosing

A controlled amount of Polyaluminium Chloride is added to the raw water or wastewater.

Rapid mixing helps distribute the coagulant throughout the water.

2. Particle Destabilization

Many fine particles suspended in water carry negative surface charges.

PAC provides positively charged aluminium species that help neutralize or destabilize these charges.

3. Floc Formation

Once destabilized, the fine particles begin to collide and combine.

They gradually form larger aggregates known as flocs.

4. Sedimentation or Flotation

The larger flocs are easier to separate from the treated water through sedimentation or flotation systems.

5. Filtration

Remaining suspended material can subsequently be removed during filtration, depending on the treatment process.

The result is clearer water with substantially reduced suspended and colloidal material.

What Does Poly Aluminium Chloride Remove From Water?

Depending on the raw-water characteristics and treatment process, PAC can assist in reducing or removing:

Suspended solids
Turbidity
Colloidal particles
Color-causing material
Certain forms of natural organic matter
Fine particulate impurities

However, PAC is primarily a coagulant, not a disinfectant.

Its main function is to aggregate impurities so that they can be removed more efficiently. Where microbial disinfection is required, treatment facilities normally use a separate disinfection process.

Why Is Poly Aluminium Chloride Used for Water Treatment?

PAC has become an important water treatment coagulant because of its effective coagulation and clarification characteristics.

Potential operational benefits include:

Effective Turbidity Removal

PAC can destabilize fine suspended particles and improve their removal during clarification.

Rapid Floc Formation

Under suitable treatment conditions, PAC can promote relatively rapid formation of larger, settleable flocs.

Effective Coagulation

The pre-hydrolyzed nature of PAC provides active aluminium species that can perform effectively under a range of treatment conditions.

Reduced Alkalinity Consumption

Compared with conventional aluminium sulfate, PAC may consume less alkalinity under certain treatment conditions.

Sludge Management

PAC can provide favorable sludge characteristics in some treatment systems.

However, actual performance depends on the PAC grade, dosage, raw-water chemistry, pH, temperature, and treatment configuration.

Poly Aluminium Chloride for Drinking Water Treatment

Suitable grades of Poly Aluminium Chloride are widely used in drinking water treatment.

Municipal water treatment plants can use PAC during coagulation and clarification to help remove suspended material before subsequent filtration and disinfection.

Typical applications include:

Municipal drinking water treatment
Surface water clarification
Reservoir water treatment
Raw-water treatment
Community water systems
Potable water treatment plants

Because drinking water is highly regulated, buyers should specify that the product is intended for potable-water treatment when requesting a quotation.

The supplied PAC grade must comply with the applicable regulations and quality requirements of the destination market.

Poly Aluminium Chloride for Wastewater Treatment

PAC is also extensively used in municipal and industrial wastewater treatment.

It can support:

Suspended solids removal
Effluent clarification
Turbidity reduction
Color reduction
Sludge treatment
Solid-liquid separation
Industrial wastewater processing

The correct PAC specification and dosage depend on the composition of the wastewater and treatment objective.

PAC for Industrial Water Treatment

Industrial facilities require water treatment for production processes, wastewater management, reuse, and environmental compliance.

Poly Aluminium Chloride can be used across industries including:

Mining and mineral processing
Food and beverage manufacturing
Textile processing
Pulp and paper manufacturing
Chemical production
Industrial wastewater treatment
Manufacturing facilities
Municipal utilities

Each industry produces different water characteristics. Therefore, PAC selection and dosage should be based on the specific treatment requirements.

Poly Aluminium Chloride in Mining Water Treatment

Mining operations can generate water containing suspended solids and fine mineral particles.

PAC may be used as part of a coagulation and clarification system to improve solid-liquid separation and reduce turbidity.

Applications can include:

Mine water clarification
Process-water treatment
Suspended mineral removal
Industrial effluent treatment
Wastewater clarification

Treatment requirements should be established according to the mine-water chemistry and applicable discharge or reuse standards.

PAC in Pulp and Paper Manufacturing

The pulp and paper industry uses substantial quantities of process water.

Poly Aluminium Chloride can support water and wastewater treatment by improving coagulation and the removal of suspended materials.

PAC may also be used in certain papermaking processes depending on the production system and product specification.

PAC for Textile Wastewater Treatment

Textile manufacturing can generate wastewater containing color, suspended material, and process chemicals.

PAC can form part of a broader wastewater treatment program designed to improve clarification and reduce certain particulate and color-causing impurities.

The treatment process may combine PAC with other physical, chemical, or biological treatment technologies.

PAC vs Aluminium Sulfate for Water Treatment

Both Poly Aluminium Chloride and aluminium sulfate (alum) are widely used aluminium-based water treatment coagulants.

However, their characteristics differ.

Property	Poly Aluminium Chloride	Aluminium Sulfate
Common Name	PAC	Alum
Primary Function	Coagulation	Coagulation
Hydrolysis	Pre-hydrolyzed	Hydrolyzes after addition
Floc Formation	Often rapid	Effective
Alkalinity Consumption	Can be lower	Generally higher
Sludge Production	Can be lower under some conditions	Treatment dependent
Water Treatment Use	Municipal & industrial	Municipal & industrial

Neither chemical is automatically the better choice for every water source.

Raw-water chemistry, pH, temperature, turbidity, treatment infrastructure, and chemical cost should all be considered.

Jar testing can help treatment operators compare the performance of different coagulants and determine an appropriate dosage.

PAC vs Ferric Chloride

Ferric chloride is another widely used water treatment coagulant.

Both products can provide effective clarification, but they differ in chemistry and operating characteristics.

PAC is aluminium-based, while ferric chloride is iron-based. Their effectiveness can vary according to raw-water pH, alkalinity, organic matter, temperature, and treatment objectives.

Water treatment operators should therefore select the coagulant according to actual treatment performance rather than assuming that one chemical will perform better under every condition.

Typical Poly Aluminium Chloride Specifications

Specifications vary according to PAC grade and manufacturer.

Product	Poly Aluminium Chloride
Abbreviation	PAC
Chemical Type	Inorganic Polymer Coagulant
Appearance	Powder or Liquid
Powder Color	White / Yellow, depending on grade
Application	Water & Wastewater Treatment
Al₂O₃ Content	Grade dependent

Choosing the Right PAC Grade

Not all Poly Aluminium Chloride products have identical specifications.

Buyers should consider:

Intended application
Drinking water or wastewater use
Al₂O₃ concentration
Basicity
Insoluble matter
Product form
Heavy-metal limits where applicable
Raw-water characteristics
Regulatory requirements

For potable-water applications, buyers should clearly specify their regulatory and technical requirements before ordering.

How Much PAC Should Be Used in Water Treatment?

There is no universal PAC dosage suitable for every water source.

The correct dosage depends on factors including:

Raw-water turbidity
pH
Alkalinity
Temperature
Organic matter
PAC concentration
Treatment objectives
Mixing conditions
Other treatment chemicals

Treatment operators commonly perform jar tests to establish an appropriate dosage before full-scale application.

This approach helps optimize clarification while avoiding unnecessary chemical consumption.
