The science behind clean water is complex, and at NINGBO INNO PHARMCHEM CO.,LTD., we believe in demystifying the advanced chemical solutions we provide. Poly Aluminium Chloride (PAC) is a prime example of such innovation, offering superior performance as a coagulant and flocculant. Understanding the chemistry of poly aluminium chloride water treatment is key to appreciating its effectiveness.

PAC is an inorganic polymer coagulant characterized by its high charge density and polymeric structure. Unlike simple metal salts, PAC consists of positively charged polynuclear aluminum complexes. When introduced into raw water, these complexes readily neutralize the negative surface charges of suspended particles, such as silt, clay, and organic matter. This process, known as charge neutralization, destabilizes the colloidal suspension, causing the particles to aggregate.

Following charge neutralization, the bridging effect of PAC becomes critical. The long polymer chains of PAC can adsorb onto multiple destabilized particles, linking them together to form larger, heavier aggregates known as flocs. This bridging mechanism is particularly efficient and contributes to the formation of robust flocs that settle rapidly. This is why it's often sought after as a high purity flocculant PAC, offering enhanced performance.

The efficiency of PAC is further amplified by its high aluminum content and adjustable basicity. Basicity, which refers to the degree of hydrolysis of aluminum, influences the speciation of aluminum complexes and their reactivity. Higher basicity generally leads to more stable and effective polynuclear species, making PAC a potent drinking water purification agent. Manufacturers carefully control these parameters to produce PAC tailored for specific water treatment challenges.

When comparing PAC to traditional coagulants, such as aluminum sulfate (alum), the advantages are clear. PAC typically requires lower dosages, operates over a broader pH range, and produces less sludge. These factors contribute to its widespread adoption as an industrial wastewater treatment chemical. Industries looking to buy PAC can leverage these efficiencies for both cost savings and improved environmental outcomes.
