When it comes to selecting coagulants for industrial water treatment, procurement managers and R&D scientists often face the choice between traditional chemicals and newer, advanced alternatives. Polyaluminium Chloride (PAC) has increasingly replaced aluminum sulfate in many applications due to its superior performance and cost-effectiveness. As a leading supplier of Polyaluminium Chloride, we aim to provide clarity on why PAC is often the preferred choice for modern industrial water solutions.

Aluminum sulfate, commonly known as alum, has been a workhorse in water treatment for decades. It functions as a coagulant by forming aluminum hydroxide precipitates that trap suspended particles. However, alum has several limitations in industrial settings. Firstly, it requires a larger dosage compared to PAC to achieve similar results. This higher consumption directly translates to increased chemical expenditure and greater volume of treatment residuals.

Secondly, alum's performance is significantly affected by water temperature and pH. It is less effective at low temperatures and requires a narrower pH range for optimal coagulation. In contrast, Polyaluminium Chloride exhibits remarkable adaptability to varying temperatures and a much wider effective pH range. This robustness makes PAC a more reliable choice for industrial processes that operate under diverse environmental conditions, reducing the need for extensive pH adjustments and ensuring consistent treatment outcomes.

The formation of flocs is another key differentiator. PAC typically forms larger, denser flocs that settle much faster than those produced by alum. This rapid sedimentation improves the efficiency of clarification processes, reduces the load on downstream filters, and leads to cleaner treated water. For industries that require high throughput or have limited sedimentation basin capacity, PAC's faster settling capability is a significant operational advantage. This is a crucial point for R&D scientists optimizing process design.

From an environmental and cost perspective, PAC also holds a distinct advantage. The lower dosage of PAC means less aluminum residue in the treated water and a reduced volume of sludge. This not only lowers disposal costs but also minimizes the environmental impact, aligning with corporate sustainability goals. When considering the total cost of ownership, including chemical usage, sludge disposal, and operational efficiency, the decision to buy PAC often proves more economical in the long run.
