Industrial Grade Polyaluminium Chloride（Solid）

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 differentwater quality.

① Solid product：2-20%.

② 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.

Aierfuke Industrial  Grade  Polyaluminium  Chloride（Solid）Advantages

1. Strong Coagulation & Flocculation

Rapidly neutralizes colloidal charges, forming large and dense flocs that settle fast—ideal for complex industrial wastewater.

2. Highly Effective on High-Turbidity & High-Color Wastewater

Works well in wastewater with suspended solids (SS), dyes, heavy metals, oils, and organic matter.

3. Lower Dosage Compared to Traditional Coagulants

Typically reduces dosage by 30–50% vs. aluminum sulfate or ferric chloride.

4. Wide pH Adaptability

Effective across pH 4–11, suitable for variable industrial water conditions.

5. Reduces Sludge Production

Produces less sludge, lowering handling and disposal cost.

6. Faster Sedimentation & Clarification

Shortens treatment cycles, improving system throughput.

7. Flexible Formulation

Available in different grades (low iron / high iron / high basicity) to meet diverse wastewater treatment requirements.

8. Cost-Effective for Large-Scale Industrial Use

Low price, high efficiency, and stable performance make it ideal for continuous or batch industrial water treatment systems.

Industrial  Grade  Polyaluminium  Chloride（Solid）FAQ

Q1: What is Industrial Grade Polyaluminium Chloride (Solid) used for?

A1: It is primarily used for industrial wastewater treatment such as dyeing, mining, paper-making, chemical, and sewage plants. It is not recommended for drinking water due to higher impurity allowance.

Q2: What is the difference between industrial-grade and drinking-grade PAC?

A2:

Industrial grade contains higher insoluble matter and may contain more iron.

Drinking grade has strict limits on heavy metals, lower impurities, and is certified for potable water systems.

Industrial PAC focuses on cost efficiency and strong coagulation for complex wastewater.

Q3: How much PAC should be used in wastewater treatment?

A3: Typical dosage is 10–50 mg/L, depending on turbidity, COD, color, and oil content.
Jar tests are recommended before full-scale application.

Q4: How should Industrial PAC be stored?

A4:

Store in a cool, dry, well-ventilated place

Avoid moisture to prevent solidification

Shelf life: 12–24 months in sealed packaging

Q5: Is PAC compatible with other treatment chemicals?

A5: Yes. Works well with:

PAM (polyacrylamide) for enhanced floc strength

Activated carbon for decolorization

Ferric coagulants depending on wastewater type

Q6: Does Industrial PAC remove heavy metals?

A6: Yes. PAC can remove heavy metals such as Cr, Pb, Cu, Zn through hydrolysis, precipitation, and adsorption mechanisms.

Q7: Can PAC be used for oily wastewater?

A7: Yes. It effectively treats emulsified oils, industrial cutting fluids, oilfield produced water, especially when combined with a flocculant.

Q8: Does PAC increase the conductivity or salt content of water?

A8: It slightly increases chloride and aluminum ions but within acceptable limits for industrial discharge. Conductivity impact is much lower than ferric chloride.

Applications Industrial Grade Polyaluminium Chloride (PAC)

1. Water Treatment: PAC is widely used in municipal water treatment plants for the coagulation and flocculation of suspended particles, helping to clarify drinking water.

2. Wastewater Treatment: It is effective in treating industrial and municipal wastewater, aiding in the removal of impurities and suspended solids, thus improving effluent quality before discharge.

3. Paper Manufacturing: In the paper industry, PAC is used as a retention aid and a coagulant to improve fiber retention and enhance the quality of the final product.

4. Textile Industry: PAC can be used in dyeing and finishing processes to help remove excess dyes and improve color fastness in textiles.

5. Mining: In the mining sector, PAC is utilized for the clarification of process water and for the treatment of mine effluents.

6. Oil and Gas: PAC can be used in drilling fluids to enhance the removal of drill cuttings and improve the stability of the borehole.

7. Construction: It is sometimes used in construction as a component in cement and concrete formulations to improve workability and reduce water content.

8. Food Processing: Certain grades of PAC can be used in food processing for clarification and purification of food products, though this requires adherence to food safety standards.

9. Pulp and Paper Industry: PAC is used to improve the quality of pulp and reduce the amount of chemical additives required in the pulping process.

10. Agriculture: It can be used in agriculture for soil treatment and improving water quality in irrigation systems.

11. Pharmaceuticals: PAC may also find applications in the pharmaceutical industry for the purification of water and other processes.

12. Cosmetics: Certain formulations may use PAC for stabilization and clarification in cosmetic products.

The effectiveness of PAC in these applications is attributed to its high charge density and ability to form larger flocs, which enhances sedimentation and removal of contaminants.

It is worth noting that when using PAC for wastewater treatment, it is recommended to conduct small-scale trials based on actual site conditions to determine the optimal dosage and treatment scheme. Furthermore, PAC can be combined with other additives, such as polyacrylamide (PAM) and activated carbon, to further enhance treatment effects and effluent quality.
