In the competitive landscape of industrial water treatment, selecting the most effective and economical coagulant is a decision that directly impacts operational efficiency and budget. For years, traditional coagulants like aluminum sulfate (alum) and ferric chloride have been standard choices. However, Polyaluminium Chloride (PAC), with its advanced inorganic polymer structure (CAS: 1327-41-9), offers a compelling alternative with significant performance and cost advantages. As a leading manufacturer and supplier, we aim to equip procurement professionals and R&D scientists with the knowledge to make informed purchasing decisions.

Understanding the Chemistry of Coagulation
Coagulation is the first step in water treatment, where destabilization of colloidal particles occurs, allowing them to aggregate into larger flocs. Traditional coagulants rely on hydrolysis to produce metal cations and hydroxides, which neutralize the negative charges of suspended particles. PAC, on the other hand, functions as a pre-hydrolyzed, charge-neutralizing polymer, often forming larger, more stable, and denser flocs more rapidly.

Performance Advantages of PAC
When comparing Polyaluminium Chloride to traditional coagulants, several performance enhancements become apparent:

  • Effectiveness in Cold Water: PAC demonstrates significantly better performance in low-temperature water, a common challenge for alum which becomes less effective as temperatures drop. This makes our PAC an ideal choice for year-round operations.
  • Floc Formation and Settling: PAC typically produces larger, stronger, and faster-settling flocs. This leads to improved sedimentation rates, reduced turbidity in the treated water, and less interference with filter media, thereby extending filter life.
  • Wider pH Range: PAC is effective over a broader pH range (typically 5-9) compared to alum, which often requires significant pH adjustment. This adaptability simplifies the treatment process and can reduce the consumption of pH adjustment chemicals.
  • Reduced Alkalinity Consumption: PAC consumes less alkalinity than alum for the same level of turbidity removal, meaning it has a less drastic effect on the water's pH and can reduce the need for costly alkali additions.

Cost-Efficiency Analysis
While the initial price per kilogram of PAC might sometimes be higher than traditional coagulants, the overall cost of treatment is often significantly lower. This is due to several factors directly impacting operational budgets:

  • Lower Dosage: As research and industrial use confirm, PAC requires lower dosages to achieve the same or better results, leading to reduced chemical consumption.
  • Reduced Sludge: The denser flocs produced by PAC result in less sludge volume, lowering sludge dewatering and disposal costs.
  • Less Chemical Addition: Reduced need for pH adjustment chemicals due to PAC’s wider operating range.
