Industrial processes often generate wastewater contaminated with heavy metals, posing significant environmental and health risks if not properly treated. Metals such as lead, cadmium, mercury, chromium, and copper can be highly toxic. Effectively removing these contaminants is a primary concern for many manufacturing sectors. Polyaluminium Chloride (PAC), a highly efficient inorganic polymer coagulant, offers a robust solution for precipitating and removing heavy metal ions from industrial water. As a leading PAC manufacturer and supplier, we provide high-performance products to help industries meet their water quality goals.

The Mechanism of Heavy Metal Removal by PAC

PAC's efficacy in heavy metal removal stems from its ability to form positively charged polymeric species. These species interact with dissolved heavy metal ions in several ways:

  • Adsorption: The highly charged polymeric structures of PAC can adsorb heavy metal ions onto their surfaces, effectively binding them.
  • Precipitation: PAC helps to adjust the water's pH and promotes the precipitation of heavy metals as insoluble hydroxides or other compounds. The formation of aluminum hydroxide flocs also aids in trapping these precipitated metals.
  • Complexation: The polymeric nature of PAC can lead to the formation of complex structures that encapsulate heavy metal ions.

The combined action leads to the formation of larger, settleable flocs that contain the bound heavy metals, allowing for their efficient removal through sedimentation, filtration, or flotation.

Key Benefits of Using PAC for Heavy Metal Remediation

  • High Removal Efficiency: PAC is highly effective in removing a broad spectrum of heavy metals, often achieving significant reductions in concentration, even for challenging ions.
  • Cost-Effectiveness: Compared to advanced treatment methods like ion exchange or membrane filtration for heavy metal removal, PAC treatment is generally more cost-effective, especially for large volumes of wastewater. Lower dosage requirements also contribute to overall savings.
  • Versatility: PAC can be used across various industrial sectors, including electroplating, mining, battery manufacturing, and chemical production, where heavy metal contamination is a concern.
  • Synergistic Effects: PAC can be used in conjunction with other treatment chemicals or processes to enhance heavy metal removal efficiency.
  • Ease of Application: As a supplier, we provide PAC in forms that are easy to handle and dose, allowing for straightforward integration into existing treatment systems.
