The selection of the appropriate coagulant is a critical decision in any water treatment process. Historically, aluminum sulfate (alum) has been a widely used coagulant. However, advancements in chemical technology have led to the development of more efficient alternatives, with Polyaluminium Chloride (PAC) emerging as a leading choice. NINGBO INNO PHARMCHEM CO.,LTD. provides insights into why PAC is often preferred.

Aluminum sulfate has been a staple in water treatment for decades due to its availability and cost-effectiveness. It works by hydrolyzing in water to form aluminum hydroxide, which then traps impurities, forming flocs. However, the use of alum can result in higher residual aluminum levels in treated water and generates significant amounts of sludge, which can be costly to dispose of. Furthermore, alum's performance can be significantly impacted by water temperature and pH, often requiring adjustments with additional chemicals.

Polyaluminium Chloride, on the other hand, offers several distinct advantages. Its pre-polymerized structure means it is already partially hydrolyzed, leading to more rapid and efficient coagulation. PAC typically requires lower dosages than alum to achieve comparable or superior results. This higher efficiency is a key factor for users looking to purchase Polyaluminium Chloride.

One of the most significant benefits of PAC is its lower residual aluminum content. This is crucial for drinking water applications where strict limits on aluminum levels are enforced for health reasons. Additionally, PAC generally produces less sludge, simplifying the downstream dewatering and disposal processes, thereby reducing operational costs. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes these advantages when advising clients on the best coagulant for their needs.

The performance of PAC across a wider range of pH and temperature conditions also makes it a more adaptable choice, especially in variable climates or challenging water sources. While the initial cost of Polyaluminium Chloride might sometimes be higher than alum on a per-unit basis, its superior performance, lower dosage requirements, and reduced sludge generation often result in a lower overall cost of operation. For businesses seeking to optimize their water treatment processes, exploring PAC from reliable sources like NINGBO INNO PHARMCHEM CO.,LTD. is a strategic move.
