Drinking Water Grade Polyaluminium Chloride

Physical and Chemical Index

Drinking water grade polyaluminium chloride 

Drinking-grade PAC

AL2O3: 30%

Method of Use

Solid products should be dissolved and diluted before input. Users can confirm the best input volume by testing and preparing agent concentration based on different water quality.

● Solid product:2-20%.

● Solid product input volume:1-15g/t.

Specific input volume should be subject to flocculation tests and experiments.

Packing and Storage

Every 25Kg of solid products should be put in one bag with inner plastic film and outer plastic woven bag. Products should be stored in the dry, ventilated and cool place inside the door for fear of damp. Don't store them together with inflammable, corrosive and toxic goods.

Wholesale Drinking Water Grade Polyaluminium Chloride

AIERFUKE supplies Wholesale Drinking Water Grade Polyaluminium Chloride (PAC) for drinking water purification, municipal water treatment, urban water supply, and other water clarification applications.

Drinking water grade PAC is a light-yellow inorganic polymer coagulant designed to promote rapid coagulation and floc formation. After being added to raw water, it helps destabilize suspended particles and colloidal impurities, allowing them to aggregate into larger flocs that can be separated through sedimentation and filtration.

For drinking water treatment plants, distributors, EPC contractors, and bulk chemical buyers, PAC selection should consider not only Al₂O₃ content but also basicity, insoluble matter, impurity control, raw water conditions, dosage, and batch-to-batch consistency.

AIERFUKE drinking water grade Polyaluminium Chloride complies with the GB15892-2020 drinking water grade standard and is available for bulk water treatment requirements.

Why Is Drinking Water Grade PAC Used in Water Treatment?

Raw surface water may contain suspended solids, colloidal particles, fine sediment, color-causing substances, and other impurities that are difficult to remove by sedimentation alone.

When Polyaluminium Chloride is dosed into water, positively charged hydrolyzed aluminum species interact with negatively charged colloidal particles. Through charge neutralization, adsorption, bridging, and sweep flocculation, fine particles combine into larger and more settleable flocs.

This makes PAC suitable for the coagulation and clarification stages of drinking water treatment.

Key treatment advantages include:

• Rapid formation of visible flocs

• Efficient turbidity and suspended solids removal

• Good solubility for chemical preparation and dosing

• Stable coagulation performance

• Lower water-insoluble matter for cleaner solution preparation

• Suitable for municipal and large-scale water treatment systems

Actual treatment efficiency depends on raw water quality, temperature, pH, mixing conditions, sedimentation design, and PAC dosage.

What Do the Key PAC Specifications Mean?

For wholesale buyers, comparing PAC only by price or Al₂O₃ percentage may not provide enough information to determine the most suitable product.

Al₂O₃ Content

Al₂O₃ content is one of the primary specifications used to identify the active aluminum content of Polyaluminium Chloride.

AIERFUKE drinking water grade solid PAC has a company specification of Al₂O₃ ≥29.5%, making it suitable for applications requiring drinking water grade PAC with controlled product quality.

Basicity

Basicity reflects the degree of hydroxylation and polymerization of PAC and can influence coagulation behavior, floc formation, and treatment performance.

AIERFUKE's company specification for this drinking water grade PAC is 65–85% basicity.

The optimum basicity should be evaluated together with raw water turbidity, alkalinity, pH, temperature, and the existing treatment process.

Water-Insoluble Matter

Insoluble matter is particularly important for drinking water treatment because excessive insoluble material may affect solution preparation, dosing equipment, and downstream clarification.

AIERFUKE's company specification limits water-insoluble matter in solid drinking water grade PAC to ≤0.08%.

Impurity Control

For drinking water treatment chemicals, buyers should also review controlled impurity indicators such as iron, arsenic, lead, cadmium, mercury, and chromium.

These indicators should be checked together with the applicable drinking water treatment standard and the requirements of the destination market.

Where Can Drinking Water Grade Polyaluminium Chloride Be Used?

Drinking Water Grade Polyaluminium Chloride is primarily intended for coagulation and clarification processes where water quality and chemical purity requirements are higher than in general industrial wastewater treatment.

Typical applications include:

Municipal Drinking Water Treatment

PAC can be used during coagulation and clarification to help remove turbidity, suspended solids, and colloidal impurities from raw water before downstream filtration and disinfection.

Urban Water Supply

For centralized urban water treatment plants, PAC supports the treatment of surface water and other raw water sources where turbidity changes with seasons or weather conditions.

Surface Water Treatment

River, reservoir, and lake water can contain varying levels of sediment, suspended particles, organic matter, and algae. PAC dosage can be adjusted according to changing raw water conditions.

Industrial Water Supply

Where industrial processes require clarified incoming water, drinking water grade PAC can also be considered when higher chemical quality and tighter impurity control are required.

How to Determine the Right PAC Dosage

There is no single PAC dosage suitable for every drinking water treatment plant.

AIERFUKE recommends dissolving and diluting solid PAC before dosing. The current product guidance provides a 2–20% preparation concentration and a reference solid PAC dosage of 1–15 g/t.

However, the final dosage should be determined through jar testing and adjusted according to actual raw water conditions.

During a jar test, operators should compare:

• Floc formation speed

• Floc size and density

• Settling speed

• Supernatant clarity

• Residual turbidity

• Chemical consumption

• Overall treatment cost

Changes in rainfall, river conditions, algae concentration, temperature, and turbidity may require the PAC dosage to be readjusted during operation.

What Should Wholesale PAC Buyers Check Before Ordering?

When sourcing Wholesale Drinking Water Grade Polyaluminium Chloride, procurement teams should evaluate more than the quoted price per metric ton.

Before placing a bulk order, it is useful to confirm:

• Product grade and intended water treatment application

• Al₂O₃ content

• Basicity range

• Water-insoluble matter

• Controlled impurity levels

• Applicable product standard

• Product appearance and solubility

• Recommended dosage

• Packaging

• Batch quality documentation

• Production and supply capacity

• Lead time and shipping arrangements

• Technical support for product selection and jar testing

For drinking water treatment projects, buyers should also confirm the regulatory and chemical requirements applicable in the country where the product will be used.
