The Chemistry of Clarity: How PAC Enhances Water Purity
Water purity is fundamental to public health and industrial processes. At the heart of achieving this purity lies the science of coagulation and flocculation, with Polyaluminium Chloride (PAC) playing a crucial role. NINGBO INNO PHARMCHEM CO.,LTD. explores the fascinating chemistry that makes PAC such an effective water treatment agent.
Polyaluminium Chloride is an inorganic polymer characterized by its complex structure, which typically involves aluminum ions linked by hydroxyl groups and chloride counter-ions. This structure results in a highly cationic species that readily interacts with negatively charged colloidal particles suspended in water. These particles, often comprising silt, clay, organic matter, and other impurities, are responsible for water turbidity and can harbor harmful microorganisms.
The primary mechanism of action for PAC is charge neutralization. The highly positive charge of the PAC molecule attracts and neutralizes the negative surface charge of these suspended particles. Once neutralized, the particles lose their stability and begin to aggregate. This aggregation process, known as flocculation, is further enhanced by the bridging action of the polymerized aluminum species in PAC. They essentially link the neutralized particles together, forming larger, visible clumps called flocs.
These flocs are significantly heavier and larger than the original suspended particles, making them easier to remove from the water. Through sedimentation, the flocs sink to the bottom of the treatment tank. Alternatively, they can be removed via flotation or filtered out using various filtration media. The efficiency of PAC in forming these robust flocs is a key reason for its widespread adoption. Compared to simpler coagulants, PAC's pre-polymerized nature allows for faster and more complete floc formation, even under challenging water conditions.
