In the pursuit of optimal water quality and efficient industrial processes, the synergistic application of different chemical agents often yields superior results. One such powerful combination in water treatment involves the use of Polyacrylamide (PAM) and Polyaluminum Chloride (PAC). While both are effective water treatment chemicals, their combined application can amplify their individual benefits, leading to more robust and cost-effective solutions. NINGBO INNO PHARMCHEM CO.,LTD. highlights the advantages of this complementary pairing.

Polyaluminum Chloride (PAC) is an inorganic polymeric coagulant. Its primary function is to neutralize the negative charges on suspended particles in water, causing them to destabilize and begin to aggregate into micro-flocs. PAC works by forming positively charged aluminum hydroxide complexes that attract and entrap these destabilized particles. This initial coagulation step is essential for preparing the water for subsequent flocculation.

Polyacrylamide (PAM), as discussed previously, acts as a flocculant. It bridges the micro-flocs formed by PAC, creating larger, heavier, and more compact flocs. These larger flocs settle more quickly and are easier to filter, thereby significantly improving the efficiency of solid-liquid separation. The choice of PAM—anionic, cationic, or non-ionic—depends on the specific characteristics of the water being treated and the type of PAC used.

The synergy between PAM and PAC is particularly evident in several ways:

  • Enhanced Flocculation: PAC initiates the process by destabilizing particles, while PAM consolidates these into larger flocs. This sequential action often results in better floc formation and faster sedimentation than using either chemical alone.
  • Improved Water Clarity: The combined action leads to more efficient removal of suspended solids and turbidity, resulting in significantly clearer treated water.
  • Reduced Chemical Dosage: Often, the combined use allows for lower dosages of both PAC and PAM compared to the dosages required if each were used independently to achieve the same level of treatment. This can lead to substantial cost savings.
  • Adaptability to Diverse Water Conditions: The combination can effectively treat a wider range of water conditions, including those with varying pH levels and contaminant types, which might challenge a single chemical agent.

When considering the industrial wastewater treatment with polyacrylamide in conjunction with PAC, it's important to understand the optimal dosage and order of addition. Typically, the coagulant (PAC) is added first, followed by the flocculant (PAM), with appropriate mixing at each stage. NINGBO INNO PHARMCHEM CO.,LTD. provides guidance on the correct application of these chemicals to maximize their synergistic benefits.

The combination of PAM and PAC represents a powerful strategy for achieving high-quality water treatment outcomes. By leveraging the strengths of both inorganic coagulation and organic flocculation, industries can ensure efficient purification, cost savings, and environmental compliance.
