Industrial cooling water systems are critical for maintaining the operational efficiency of various industries, from power generation to manufacturing. However, these systems are prone to issues like scaling, fouling, and corrosion, which can significantly reduce heat transfer efficiency and lead to equipment damage. Polyaluminium Chloride (PAC) is an effective chemical treatment agent that plays a crucial role in mitigating these problems. NINGBO INNO PHARMCHEM CO.,LTD., as a seasoned supplier of industrial chemicals, highlights the benefits of using PAC in cooling water treatment.

The Challenges in Cooling Water Systems

Cooling water, often sourced from rivers, lakes, or municipal supplies, contains dissolved minerals, suspended solids, and microorganisms. As this water circulates and evaporates in cooling towers, dissolved solids become concentrated. This high concentration can lead to the precipitation of mineral scales (like calcium carbonate and calcium sulfate) on heat exchanger surfaces and within pipes. Scaling acts as an insulating layer, drastically reducing the system's heat transfer efficiency and increasing energy consumption. Furthermore, microbial growth can lead to biofouling, and the presence of dissolved oxygen and aggressive ions can accelerate corrosion of metal components.

How PAC Works in Circulating Water Treatment

Polyaluminium Chloride functions as a coagulant and flocculant in industrial circulating water. Its primary role is to remove suspended solids and colloidal matter that contribute to turbidity and fouling. When added to the circulating water, PAC neutralizes the surface charges of these contaminants, causing them to aggregate into larger flocs. These larger particles are then more easily captured by filtration systems or settle out, preventing them from depositing on heat transfer surfaces. While PAC is not typically used as a primary scale or corrosion inhibitor, by removing the suspended matter that often initiates these processes, it indirectly helps maintain system cleanliness and efficiency.

Key Benefits of Using PAC in Cooling Towers

Integrating PAC into your cooling water treatment program offers several advantages:

  • Improved Heat Transfer Efficiency: By preventing the buildup of fouling and suspended solids, PAC helps maintain optimal heat exchange performance.
  • Reduced Fouling: It effectively removes suspended impurities that can contribute to biofouling and particulate deposition.
  • Enhanced System Cleanliness: Regular use of PAC contributes to a cleaner internal environment for the cooling system, reducing the likelihood of blockages.
  • Complementary Treatment: PAC works well in conjunction with other water treatment chemicals like scale inhibitors and corrosion inhibitors, forming a comprehensive treatment strategy.
