The choice of coagulant is a critical decision in water treatment. Historically, aluminum sulfate (alum) has been a common choice, but Polyaluminium Chloride (PAC) has increasingly become the preferred option due to its superior performance characteristics. NINGBO INNO PHARMCHEM CO.,LTD. provides a comparative analysis to illustrate why PAC is often the better choice for modern water treatment needs.

One of the primary advantages of Polyaluminium Chloride over aluminum sulfate lies in its chemical structure. PAC is a pre-polymerized inorganic compound, meaning it contains more polymerized aluminum species. This advanced structure grants PAC a higher charge density, enabling it to neutralize and destabilize suspended particles in water more effectively and rapidly than aluminum sulfate. This leads to quicker formation of larger, more settleable flocs.

This enhanced flocculation performance translates directly into several key benefits. For industrial wastewater treatment, the larger flocs formed by PAC settle more quickly, reducing the time required for sedimentation. This increased efficiency can lead to higher throughput in treatment plants. Furthermore, PAC generally requires a lower dosage compared to aluminum sulfate to achieve similar or better results, contributing to cost savings. Understanding the best polyaluminium chloride dosage for your specific application is key to maximizing these benefits.

Sludge production is another significant differentiator. Aluminum sulfate tends to produce a larger volume of sludge, which can incur higher disposal costs and operational burdens. Polyaluminium Chloride, on the other hand, generally results in less sludge formation. This reduction in sludge volume is a major environmental and economic advantage, making PAC a more sustainable choice for wastewater management.

When it comes to drinking water purification, the purity of the coagulant is paramount. High purity polyaluminium chloride, as supplied by NINGBO INNO PHARMCHEM CO.,LTD., offers a distinct advantage with its lower levels of impurities, including iron and heavy metals. This contributes to a safer final product and requires less post-treatment to meet potable water standards. The effectiveness of PAC in removing organic matter and turbidity at lower temperatures also makes it more reliable across varying environmental conditions.

In conclusion, while aluminum sulfate has served its purpose, Polyaluminium Chloride offers a more advanced, efficient, and often more economical solution for both industrial wastewater treatment and drinking water purification. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing high-quality PAC that meets the evolving demands of the water treatment industry.
