The journey from contaminated water to pure, usable water is a complex process, often relying on sophisticated chemical interventions. Polyaluminium Chloride (PAC) is a key player in this transformation, acting as a powerful coagulant that underpins effective water purification. NINGBO INNO PHARMCHEM CO.,LTD. provides insight into the scientific principles that make PAC so effective.

At its core, PAC functions by neutralizing the electrostatic charges of suspended particles in water. Raw water sources typically contain a variety of negatively charged colloidal particles, such as silt, clay, and organic matter, which keep them dispersed and stable. PAC, when introduced into the water, dissociates to form highly charged polymeric aluminum species, such as Al13 polymers. These positively charged species effectively neutralize the negative charges on the suspended particles, a process known as charge neutralization. This destabilizes the colloids, allowing them to begin aggregating.

Following charge neutralization, the process of flocculation takes over. The destabilized particles, now attracted to each other, start to collide and aggregate, forming larger, visible clumps called flocs. PAC's high molecular weight and polymeric nature contribute to its efficacy in bridging these particles together, creating robust and settleable flocs. This mechanism is crucial for efficient solid-liquid separation.

The efficiency of PAC in flocculation is influenced by several factors, including pH, temperature, and the presence of other substances in the water. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes that PAC is effective over a wide pH range, which is a significant advantage in various water treatment scenarios. The formed flocs are typically denser and more compact than those produced by simpler coagulants, leading to faster settling rates and easier removal through sedimentation, filtration, or flotation.

The overall impact of PAC in water treatment is profound. By facilitating the removal of turbidity, color, and various dissolved and suspended impurities, PAC significantly enhances water clarity and quality. This scientific mechanism makes PAC an indispensable tool for ensuring the safety and usability of water for both potable and industrial purposes. NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying PAC that consistently delivers these scientifically proven benefits.
