Polyaluminium Chloride For Sale

In the industrial and municipal water treatment sectors, many facilities still face persistent challenges such as low flocculation efficiency, unstable water clarity, and excessive sludge generation. Polyaluminium Chloride (PAC), with its outstanding coagulation performance, lower required dosage, and ability to deliver cleaner, clearer water, has become one of the most trusted choices among industrial buyers and municipal engineers.

Whether used for drinking water purification, wastewater clarification, or industrial process treatment, sourcing high-quality PAC from a reliable supplier is essential for maintaining stable operations and ensuring compliance. As a leading direct-sale manufacturer, Hengsin offers high-purity PAC to global industrial buyers, delivering consistent quality, highly competitive pricing, and dependable logistics for a wide range of water treatment applications.

In the sections below, we will explore the characteristics, applications, and key purchasing considerations of Polyaluminium Chloride to understand how it has become the coagulant of choice in modern water purification systems.

Polyaluminium Chloride (PAC) is an inorganic polymer coagulant used to remove suspended solids, organics, and turbidity from water. Its chemical composition includes aluminum, chlorine, and hydroxide ions, typically represented as [Al₂(OH)nCl₆₋ₙ]m.

When PAC is added to water, it rapidly hydrolyzes to form polymeric aluminum ions with strong positive charges. These ions interact with negatively charged suspended particles, colloids, and organics through charge neutralization and adsorption-bridging, forming large flocs that quickly settle out of solution.

1. Strong coagulation performance, lower dosage — PAC has a high active component content and excellent charge neutralization ability. Its flocculation performance exceeds that of traditional coagulants (like aluminum sulfate or alum), typically requiring 30–50% less dosage.
2. Broad applicability to various water qualities — PAC maintains excellent coagulation performance within a pH range of 4–11, showing stable results for different water sources such as surface water, groundwater, and industrial wastewater.
3. Less sludge, clearer effluent — PAC forms dense flocs with small volume and low water content, which settle quickly. The treated water has low residual aluminum and turbidity, easing the burden on downstream filtration.
4. Good solubility and easy operation — PAC dissolves quickly in both solid powder and liquid forms, making it convenient for on-site operations and automatic dosing systems.
5. Stable storage and safe transport — Compared with aluminum sulfate or liquid chlorine, PAC has good thermal and chemical stability, resists decomposition, and is suitable for long-distance transport and long-term storage.

With these advantages, PAC has become one of the most widely used and cost-effective coagulants in the global water treatment industry, providing reliable chemical solutions for drinking water purification, wastewater treatment, and industrial water recycling.

Thanks to its strong flocculation performance, wide applicability, and excellent cost-effectiveness, PAC has become an indispensable core chemical in various industrial and public water treatment systems. Below are typical applications of PAC across different sectors:
