The selection of an appropriate coagulant is a cornerstone of effective water treatment. For decades, Aluminum Sulfate (also known as alum) has been a staple in the industry. However, Polyaluminium Chloride (PAC) has increasingly gained prominence as a superior alternative, offering enhanced performance and environmental benefits. As a leading Polyaluminium Chloride manufacturer in China, we frequently guide our clients on why PAC is often the more advantageous choice for their water purification needs.

Understanding the Coagulant Action

Both Aluminum Sulfate and Polyaluminium Chloride function as coagulants, working to destabilize and aggregate suspended particles and colloidal matter in water. This process is essential for removing turbidity, color, and various contaminants. However, their chemical structures and hydrolysis behaviors differ significantly, leading to distinct performance characteristics.

Key Differences and Advantages of PAC

When you buy Polyaluminium Chloride, you are choosing a more advanced and efficient coagulant. Here's why:

  • Efficiency and Dosage: PAC typically requires lower dosages than Aluminum Sulfate to achieve equivalent or superior turbidity removal. This means less chemical consumption, leading to cost savings on materials and transportation.
  • Performance Over Wider pH Range: PAC generally performs effectively across a broader range of water pH values compared to Aluminum Sulfate, which can be more sensitive to pH fluctuations. This reduces the need for extensive pH adjustment chemicals.
  • Floc Formation and Settling: PAC forms larger, denser, and stronger flocs that settle more rapidly. This improved flocculation leads to clearer supernatant water and more efficient sludge separation, potentially reducing sedimentation and filtration times.
  • Reduced Sludge Volume: A significant advantage of PAC is that it typically generates less sludge compared to Aluminum Sulfate. This reduction in sludge volume lowers disposal costs, which are a substantial operational expense in many water treatment facilities.
  • Lower Residual Aluminum: PAC treatments generally result in lower residual aluminum levels in the treated water, which is important for both aesthetic quality and health considerations.
  • Temperature Tolerance: While both can be affected by temperature, PAC often exhibits more stable performance in colder water conditions where Aluminum Sulfate can become less effective.
