China Composite Polyaluminum Chloride (CPAC) Suppliers - Multifunctional Water Treatment Agent from Reliable Factory

Composite Polyaluminum Chloride (CPAC) is an advanced multifunctional water treatment agent developed by combining Polyaluminum Chloride (PAC) with other effective substances such as aluminum salts, iron salts, and organic flocculants. This innovative product leverages the synergy effect of its various components to overcome the limitations of traditional PAC, which can struggle with low-turbidity wastewater and the simultaneous decolorization and removal of heavy metals. As a leading solution from China, CPAC is designed to provide efficient flocculation and multifunctional purification tailored for complex water quality challenges. Unlike conventional PAC that primarily relies on electrical neutralization + adsorption bridging, CPAC incorporates additional elements like iron salts to effectively tackle multiple pollutants including suspended solids, colloids, organic matter, and heavy metals. Trust in our factory for high-quality CPAC solutions, making it a superior flocculant choice for water treatment suppliers worldwide.

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

Through "Modularization compounding" design, CPAC can flexibly adjust the formula according to different wastewater characteristics, for example:

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 advanced coagulant formulated by combining standard Poly Aluminium Chloride (PAC) with additional agents such as iron salts, activated carbon, polyacrylamide, or diatomite. Unlike single PAC, which works optimally within a pH range of 6–9, CPAC extends effective treatment to pH 4–11 and addresses a wider range of contaminants including heavy metals, organic matter, and high-turbidity particles.

Q What types of wastewater is CPAC most suitable for?

CPAC is suitable for a broad range of industrial and municipal wastewater types, including: municipal sewage, printing and dyeing wastewater (decolorization and COD reduction), electroplating wastewater (heavy metal removal), coal washing and mining wastewater (high turbidity), papermaking black liquor, and food processing wastewater. Its modular formulation allows it to be tailored to specific water quality conditions.

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

CPAC formulated with sodium sulfide and iron salts demonstrates a high removal rate for heavy metals such as Cr⁶⁺ and Cu²⁺ found in electroplating wastewater. The sulfide component complexes heavy metal ions while the iron salt component facilitates netting and precipitation, achieving efficient and reliable heavy metal removal that meets discharge standards.

Q Can CPAC help reduce sludge volume compared to standard PAC?

Yes. CPAC formulations incorporating composite components such as diatomite enhance the compactness and density of flocs formed during the coagulation process. This results in a sludge volume reduction of approximately 20%–30% compared to using standard single PAC, which directly lowers the cost and effort associated with downstream pressure filtration and sludge disposal.

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

Before applying CPAC, it is essential to conduct a thorough water quality analysis of the target wastewater. Key parameters to test include pH value, COD (Chemical Oxygen Demand), and heavy metal concentrations. The CPAC formula should then be adjusted based on these results — for instance, acidic wastewater (low pH) requires a higher proportion of iron salts in the formulation to ensure optimal coagulation performance.

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

For liquid-type CPAC, it should be stored in a sealed container in a cool environment with a temperature not exceeding 30°C. The shelf life for liquid CPAC is 12 months. For solid-type CPAC, it should be stored in a dry location with relative humidity not exceeding 60% to prevent moisture absorption and caking. Proper storage ensures product stability and consistent treatment performance.
