The journey to clean water relies on sophisticated chemical processes, and Poly Aluminum Chloride (PAC) plays a pivotal role in these transformations. Understanding the science behind how PAC works is key to appreciating its effectiveness in water purification. NINGBO INNO PHARMCHEM CO.,LTD. breaks down the coagulation and flocculation processes driven by PAC.

Water sources often contain microscopic suspended and colloidal particles that do not readily settle. These particles, typically in the size range of 1 to 100 nanometers, often carry a negative surface charge. This charge stabilizes them within the water, making them difficult to remove through simple sedimentation. This is where coagulants like Poly Aluminum Chloride come into play.

The primary mechanism of PAC is charge neutralization. As an inorganic polymer coagulant, PAC introduces positively charged aluminum species into the water. These positive charges effectively neutralize the negative charges on the colloidal particles. This neutralization destabilizes the particles, preventing them from repelling each other and allowing them to begin aggregating.

Once the charges are neutralized, the process of flocculation takes over. PAC, with its polymeric structure, also acts as a bridging agent. The positively charged aluminum ions and polymer chains bind to multiple destabilized particles simultaneously. This creates larger, heavier aggregates known as flocs. The formation of these flocs is crucial, as their increased size and weight facilitate their separation from the water.

The efficiency of Poly Aluminum Chloride in forming these flocs is a significant advantage. The rapid formation and robust nature of PAC-induced flocs lead to quicker settling times in sedimentation tanks. This enhanced settling behavior improves the overall efficiency of the water treatment plant, allowing for more effective removal of impurities.

The effectiveness of PAC is further influenced by factors like pH and water temperature. By understanding these scientific principles and conducting necessary tests, operators can optimize the dosage and application of Poly Aluminum Chloride to achieve the best possible water quality. For industries relying on pristine water, the precise application of poly aluminum chloride ensures consistent results.
