Maintaining water quality is a cornerstone of efficient and sustainable industrial operations. From process water to effluent discharge, managing water effectively is crucial for compliance, product quality, and environmental responsibility. Polyaluminium Chloride (PAC), a sophisticated inorganic polymer, plays a pivotal role in industrial water purification, acting as a highly efficient coagulant and flocculant. At NINGBO INNO PHARMCHEM CO.,LTD., we are committed to supplying high-quality PAC that empowers industries to achieve superior water management. This overview explores the essential functions and benefits of PAC in industrial water purification.

Understanding PAC's Function in Water Purification

Polyaluminium Chloride (CAS 1327-41-9) is a complex inorganic polymer that acts as a primary coagulant. Its efficacy stems from its molecular structure, which contains positively charged aluminum species. When introduced into water containing negatively charged suspended particles, colloids, and dissolved organic matter, PAC performs several key functions:

  • Charge Neutralization: The positively charged aluminum species in PAC neutralize the negative surface charges of dispersed particles. This destabilizes the colloidal suspension, preventing particles from repelling each other and initiating the aggregation process.
  • Coagulation and Flocculation: After charge neutralization, the long polymer chains of PAC can bridge between destabilized particles, forming larger, more stable aggregates known as flocs. This bridging mechanism significantly enhances the removal of suspended solids, turbidity, and certain dissolved impurities.
  • Sedimentation Enhancement: The flocs formed by PAC are typically denser and larger than those produced by simpler coagulants. This leads to faster settling rates in sedimentation tanks, improving the efficiency of solid-liquid separation processes.
  • Removal of Dissolved Pollutants: In addition to suspended solids, PAC can also aid in the removal of certain dissolved organic matter, heavy metals, and phosphates through adsorption and co-precipitation mechanisms.

Key Benefits for Industrial Applications

The widespread adoption of PAC in industrial water purification is driven by its numerous advantages:

  • Versatility: PAC is effective in treating a wide range of water sources, including raw river water, groundwater, industrial process water, and various types of industrial wastewater (e.g., from textile, paper, mining, and food processing industries).
  • High Performance: It offers excellent performance in clarifying high-turbidity water, even under low-temperature conditions, which are often challenging for conventional coagulants.
  • Cost-Effectiveness: Lower dosage requirements, reduced sludge production, and minimized need for pH adjustment contribute to a lower overall treatment cost compared to many alternative chemicals. For businesses looking to purchase PAC, these cost benefits are a significant factor.
  • Improved Treated Water Quality: The efficient removal of impurities results in clearer, purer water, which is essential for many industrial processes and for meeting stringent discharge standards.
