China CPAC - Superior Composite Polyaluminum Chloride Water Treatment Agent from Reliable Suppliers and Factory

Composite Polyaluminum Chloride (CPAC) is an advanced multifunctional water treatment agent, developed from the traditional Polyaluminum Chloride (PAC). This innovative solution is created by combining various functional substances, such as aluminum salts, iron salts, and organic flocculants, to enhance its effectiveness. CPAC utilizes the synergy effect of these components to overcome the limitations of standard PAC, particularly in treating low-turbidity wastewater and simultaneously addressing issues like decolorization and heavy metal removal.
While traditional PAC relies primarily on electrical neutralization + adsorption bridging, CPAC offers a tailored approach to tackle multiple pollution challenges. By integrating additional components, such as iron salts, CPAC significantly improves its ability to capture suspended solids, colloids, organic matter, and heavy metals. As a result, CPAC stands out as an upgraded flocculant in the water treatment sector, making it a preferred choice among customers seeking effective solutions.
If you are looking for reliable suppliers of high-quality CPAC in China, our factory is dedicated to providing top-notch water treatment solutions to meet diverse needs.

Product Description

Core Features

1. Multi-effect synergy to address the "shortcomings" of single PAC

• Complete the pH adaptation range: The optimal pH for single PAC is 6–9, while CPAC can extend the applicable pH to 4–11 by adding iron salts (such as polyferric sulfate) or organic bases (such as polyacrylamide), adapting to highly acidic (such as mine wastewater) or highly alkaline (such as papermaking black liquor) scenarios.

• Enhanced Decolorization/Heavy Metal Removal: For printing and dyeing wastewater (containing dye pigments) or electroplating wastewater (containing Cr⁶⁺, Cu²⁺), CPAC can be compounded with activated carbon (adsorbing pigments) or sulfides (complexing heavy metals), with a high heavy metal removal rate.

• Reduce sludge production: Composite components (such as diatomite) can enhance the compactness of flocs, with the sludge volume reduced by 20%–30% compared to single PAC, thereby reducing the subsequent pressure filtration cost.

2. Adapt to complex water quality, covering over 90% of industrial scenarios

• High turbidity wastewater (such as coal washing and mining wastewater): Compound high polymerization degree PAC (Al₂O₃ ≥ 15%) + diatomite (enhanced filtration), turbidity removal rate ≥ 98%.

• High organic wastewater (such as printing and dyeing, food processing wastewater): Compound activated carbon (adsorbing COD) + polyacrylamide (coagulant aid), with a COD removal rate ≥ 50%.

• Heavy metal-containing wastewater (such as electroplating and chemical wastewater): compounded sodium sulfide (complexing heavy metals) + iron salt (netting and precipitation).

Applicable Scenarios

🏢 Advanced Treatment of Municipal Sewage

🎨 Decolorization and COD Reduction of Printing and Dyeing Wastewater

⚙️ Removal of Heavy Metals from Electroplating Wastewater

♻️ Recycling of Papermaking / Mining Wastewater

Precautions for Use

🧪

Water quality testing first: Before use, it is necessary to test the pH, COD, and heavy metal content of wastewater, and adjust the CPAC formula based on the data (for example, acidic wastewater requires an increase in the proportion of iron salts).

📦

Storage Conditions: Liquid type should be stored sealed in a cool place (temperature ≤ 30°C), solid type should be stacked to prevent moisture (humidity ≤ 60%), and the shelf life of the liquid type is 12 months.

Frequently Asked Questions

Q What is Compound Poly Aluminium Chloride (CPAC) and how does it differ from standard PAC?

CPAC is an enhanced coagulant formulated by combining standard Poly Aluminium Chloride (PAC) with additional agents such as iron salts, activated carbon, or polyacrylamide. Unlike single PAC — which works optimally in a pH range of 6–9 — CPAC can operate effectively across a much wider pH range of 4–11, and offers superior performance for decolorization, heavy metal removal, and sludge reduction.

Q What types of wastewater is CPAC most suitable for?

CPAC is suitable for a wide range of industrial and municipal wastewater types, including: municipal sewage (advanced treatment), printing and dyeing wastewater (decolorization and COD reduction), electroplating wastewater (heavy metal removal), coal washing and mining wastewater (high turbidity treatment), food processing wastewater, and papermaking/mining recycling water.

Q How effective is CPAC at removing heavy metals from electroplating wastewater?

CPAC achieves a high heavy metal removal rate when compounded with sodium sulfide (for complexing heavy metals such as Cr⁶⁺ and Cu²⁺) and iron salts (for netting and precipitation). This combination is specifically designed for electroplating and chemical wastewater with complex contamination profiles.

Q Can CPAC reduce sludge production compared to standard PAC?

Yes. Composite components such as diatomite enhance the compactness of flocs formed during treatment. This results in a sludge volume reduction of approximately 20%–30% compared to standard PAC, which significantly lowers subsequent pressure filtration costs and overall operational expenses.

Q What should be done before applying CPAC to a wastewater treatment system?

It is essential to conduct a water quality analysis before use. This includes testing the wastewater's pH level, COD concentration, and heavy metal content. Based on these results, the CPAC formula should be adjusted accordingly — for example, acidic wastewater typically requires a higher proportion of iron salts in the compound formulation.

Q What are the storage requirements for CPAC, and what is its shelf life?

Liquid CPAC should be stored in a sealed container in a cool environment with a temperature not exceeding 30°C. Solid CPAC should be kept in a dry location with relative humidity not exceeding 60%, stacked properly to prevent moisture absorption. The shelf life for the liquid form is 12 months under the recommended storage conditions.
