Access to clean and safe drinking water is a fundamental necessity for public health and well-being. The purification of raw water sources, such as rivers, lakes, and groundwater, involves removing impurities, turbidity, and harmful microorganisms. Polyaluminum Chloride (PAC) has become a critical component in modern water treatment plants globally, playing a vital role in delivering potable water. As a leading manufacturer and supplier of PAC from China, we emphasize the importance of this versatile coagulant.

How PAC Purifies Drinking Water:

The effectiveness of PAC in drinking water purification stems from its sophisticated coagulation and flocculation properties. When added to raw water, PAC initiates a series of chemical reactions:

  • Hydrolysis and Complex Formation: PAC hydrolyzes in water to form positively charged polynuclear aluminum complexes.
  • Charge Neutralization: These positively charged complexes neutralize the negative charges present on suspended colloidal particles, organic matter, and dissolved impurities in the water. This destabilizes the impurities, preventing them from remaining suspended.
  • Adsorption and Bridging: The polynuclear complexes then adsorb these destabilized impurities and form bridges between them, initiating the process of flocculation.
  • Floc Formation and Sedimentation: This leads to the formation of larger, heavier flocs that are easily removed from the water through sedimentation (settling) and subsequent filtration processes.

Why PAC is Preferred for Drinking Water Treatment:

Several advantages make PAC the coagulant of choice for drinking water plants:

  • High Efficiency: PAC is significantly more efficient than traditional coagulants like aluminum sulfate, often requiring smaller dosages to achieve the same or better results. This translates to lower operational costs.
  • Rapid Flocculation: It promotes the rapid formation of large, dense flocs that settle quickly, increasing the throughput of treatment plants.
  • Wide pH Range: PAC performs effectively across a broader pH range, reducing the need for extensive pH adjustment, which is often required with other coagulants.
  • Low Impurity Content: When sourced from reputable manufacturers, PAC for drinking water applications is produced to meet stringent purity standards, ensuring minimal levels of harmful heavy metals and other contaminants.
  • Reduced Sludge Production: Compared to some traditional coagulants, PAC can produce less sludge, simplifying sludge disposal and reducing associated costs.

Sourcing High-Quality PAC from China:

Ensuring the quality of PAC used in drinking water is paramount. As a leading China manufacturer, we adhere to strict quality control protocols to produce PAC that meets international drinking water standards. Our products typically exhibit:

  • High Al2O3 content for maximum efficacy.
  • Low levels of heavy metals (As, Pb, Cd, Hg).
  • Consistent particle size and solubility for easy handling and dosing.
  • Compliance with relevant national and international standards.

By choosing to buy PAC from a reliable China supplier, water treatment facilities can secure a high-quality, cost-effective, and efficient solution for producing safe and clean drinking water. We are committed to supplying PAC that meets the highest standards, supporting public health initiatives worldwide.
