At NINGBO INNO PHARMCHEM CO.,LTD., we believe in demystifying the science behind our advanced chemical solutions. Poly Aluminium Chloride (PAC) is a prime example of such a solution, playing a pivotal role in water purification and treatment. Understanding the fundamental principles of how PAC works allows us to appreciate its effectiveness as a high-performance water coagulant and its significance in producing clean water. This article explores the science of superior flocculation powered by PAC.

Flocculation is a critical step in water treatment, involving the aggregation of finely dispersed suspended particles into larger, settleable or filterable masses called flocs. In natural water sources and industrial effluents, particles like clay, silt, organic matter, and colloids often carry a negative electrical charge. This negative charge causes them to repel each other, remaining dispersed and difficult to remove. The primary mechanism of PAC action is charge neutralization. PAC, being a polymeric inorganic coagulant, contains positively charged aluminum species. When introduced into water, these positive charges effectively neutralize the negative surface charges on the suspended particles. This neutralization reduces inter-particle repulsion, allowing the particles to approach each other closely enough for van der Waals forces to initiate aggregation.

Beyond charge neutralization, PAC also contributes to floc formation through sweep flocculation. As the PAC hydrolyzes in water, it forms aluminum hydroxide polymers. These polymeric chains can physically enmesh and entrap dispersed particles as they precipitate. This process, known as sweep flocculation, is particularly effective in removing very fine particles that might not be fully neutralized by charge alone. The resulting flocs are therefore a combination of aggregated particles and precipitated aluminum hydroxide, leading to a denser and more robust floc structure. This is why searching for 'long tail keyword' terms often highlights the efficiency of this dual mechanism.

The molecular structure of PAC, characterized by its high molecular weight and a range of aluminum species with varying degrees of polymerization, contributes to its superior performance. Unlike simpler inorganic salts, PAC's polymeric nature allows it to bridge between particles more effectively, enhancing the strength and size of the flocs. This advanced structure is key to its role as a superior flocculant and its effectiveness in industrial wastewater treatment. When comparing chemical auxiliary for paper industry applications, for instance, the ability to create strong, stable flocs is crucial for performance.
