In the critical field of wastewater treatment, the selection of the right coagulant is paramount. For decades, aluminum sulfate (alum) has been a common choice, but the emergence of Polyaluminium Chloride (PAC) has presented a more advanced and often superior alternative. NINGBO INNO PHARMCHEM CO.,LTD. delves into why PAC is increasingly the preferred coagulant for modern wastewater management.

The fundamental difference lies in their chemical structures and how they interact with impurities in water. Aluminum sulfate, a traditional inorganic salt, neutralizes charges but can be less efficient and requires higher dosages. This often leads to increased residual aluminum in treated water and a greater volume of sludge. In contrast, Polyaluminium Chloride is a pre-polymerized inorganic coagulant. Its complex structure allows for more effective charge neutralization and bridging, leading to faster floc formation and improved settling characteristics. This means that polyaluminium chloride for wastewater treatment can achieve better results with smaller amounts.

When considering the best coagulant for wastewater, several factors favor PAC. Firstly, its effectiveness over a wider pH range means less reliance on pH adjustment chemicals, further reducing operational costs. Secondly, the reduced dosage rates for PAC translate directly into lower chemical purchase volumes. This efficiency is a key reason why many industries are looking to buy polyaluminium chloride.

Moreover, the floc formed by PAC is typically denser and settles more rapidly than that formed by alum. This improved settling rate can increase the capacity of sedimentation tanks and enhance the efficiency of downstream filtration processes. The reduced residual aluminum content in the final treated water is also a significant environmental and health advantage. These attributes make PAC a highly attractive option for businesses seeking effective and environmentally responsible treatment solutions.

NINGBO INNO PHARMCHEM CO.,LTD. offers high-quality PAC that adheres to stringent industry standards. By understanding the comparative benefits, industries can make informed decisions to optimize their wastewater treatment operations, ensuring compliance and sustainability.
