Product Description
Polyaluminum Chloride (PAC), as an efficient and multifunctional inorganic polymer flocculant, has gradually become an indispensable material in water treatment and various industrial fields, thanks to its outstanding performance and wide range of applications. This article will provide a detailed introduction to the characteristics, production processes, application fields, and significant role in sustainable development of Polyaluminum Chloride.
Characteristics of Polyaluminum Chloride
(1) Physical Properties
Polyaluminum Chloride typically appears as yellow, light yellow, or white powders or granules. In its liquid form, it is a light yellow to colorless transparent liquid. It has good solubility in water, dissolving quickly to form a colorless or light yellow transparent solution. Due to its strong hygroscopic nature, it requires sealed packaging during storage to prevent moisture absorption. Additionally, Polyaluminum Chloride is highly stable, with spray-dried products maintaining good performance under various water quality conditions.
(2) Chemical Properties
Polyaluminum Chloride is an inorganic polymer compound with the chemical formula
where n is an integer between 1 and 5, and m represents the degree of polymerization. It exhibits strong acidity, with a pH value typically ranging from 3.5 to 5.0, which allows it to adjust the acidity and alkalinity of solutions. Moreover, Polyaluminum Chloride has a certain level of corrosiveness, so precautions should be taken during its use.
(3) Flocculation Performance
The core advantage of Polyaluminum Chloride lies in its excellent flocculation performance. It can rapidly hydrolyze in water to generate a large amount of aluminum hydroxide colloids. These colloids possess strong adsorption capabilities and electrostatic neutralization effects, effectively adsorbing suspended particles, colloidal particles, heavy metal ions, and other harmful substances in water. This process forms large and dense flocs, facilitating rapid sedimentation and significantly reducing water turbidity. Compared to traditional flocculants, Polyaluminum Chloride achieves good treatment effects at low dosages, with dense flocs and fast sedimentation rates, resulting in high-quality treated water.

Application
1. Drinking Water Treatment
• Polyaluminum Chloride as a Flocculant: Polyaluminum Chloride (PAC) can effectively remove suspended solids, colloidal particles, heavy metal ions, and other harmful substances from water, significantly improving water quality. It achieves good treatment results at low dosages, with dense flocs and fast sedimentation rates, resulting in high-quality treated water. Additionally, PAC has the ability to adjust the acidity and alkalinity of water, keeping the pH value within an appropriate range and further enhancing the safety of drinking water.
• Practical Application: In practice, PAC is often used in combination with high-molecular flocculants (such as polyacrylamide) to further enhance flocculation effects. For example, in a municipal water treatment plant, the combination of PAC and polyacrylamide reduced the water turbidity from 20NTU to below 0.5NTU, significantly improving the clarity and safety of drinking water.
2. Wastewater Treatment
• Role of Polyaluminum Chloride in Wastewater Treatment: Polyaluminum Chloride (PAC) also plays a significant role in wastewater treatment. It can effectively remove oils, dyes, petroleum substances, and other organic pollutants from industrial and domestic wastewater, enhancing the biodegradability of the wastewater. For example, in the wastewater treatment process of a textile printing and dyeing factory, the use of PAC as a flocculant reduced the Chemical Oxygen Demand (COD) in the wastewater from 800 mg/L to below 200 mg/L, significantly improving the treatment effectiveness.
• Beyond Pollutant Removal: In addition to removing pollutants, PAC can also adjust the pH of wastewater, improving the microbial environment during the treatment process and further enhancing treatment efficiency. Moreover, PAC performs well in sludge dewatering, improving the dewatering properties of sludge, reducing its moisture content, and lowering the cost of sludge treatment.
3. River Water Treatment
• Addressing River Water Pollution: With the acceleration of urbanization, the problem of river water pollution has become increasingly severe. Polyaluminum Chloride (PAC) is effective in removing algae, suspended solids, and harmful substances from river water, improving water clarity and quality. For example, in a black and odorous river remediation project in a city, regular application of PAC to the river reduced the water turbidity from 100 NTU to below 10 NTU, significantly improving the water quality and ecological environment of the river.
Packaging & Shipping
1. Packaging Materials
• Inner Packaging: Polyethylene (PE) film bags should be used, with a thickness of no less than 0.08 mm, to ensure good sealability and moisture resistance.
• Outer Packaging: Polypropylene (PP) woven bags are typically used, which have high strength and wear resistance, and can withstand the pressure and impact during transportation and storage. The closures of both the inner and outer bags should be sturdy and leak-proof.
2. Packaging Specifications
• Solid Product: Common packaging sizes are 25 kg or 50 kg per bag.
3. Transportation Conditions
• Avoiding High Temperatures and Direct Sunlight: Prevent exposure of Polyaluminum Chloride to high temperatures and direct sunlight during transportation to avoid quality degradation. During summer transportation, it is advisable to install awning poles or set up sunshades on the vehicle to provide ventilation and shade.
• Preventing Moisture: The product should be covered during transportation to avoid rain and moisture. Desiccants can be added inside the packaging bags to absorb excess moisture.
