At NINGBO INNO PHARMCHEM CO.,LTD., we recognize that effective industrial water treatment requires more than just a high-quality chemical; it demands the right chemical for the specific application. Poly Aluminium Chloride (PAC) is a versatile coagulant, but its optimal performance can depend on selecting the appropriate grade. This guide outlines key considerations for industries looking to leverage PAC for their water treatment needs.

1. Water Quality and Contaminant Profile: The first crucial step is understanding the characteristics of the raw water or wastewater. Factors such as turbidity levels, pH, temperature, the presence of specific contaminants (e.g., heavy metals, organic matter, oils), and the overall ionic strength of the water will influence which PAC formulation is most effective. For instance, higher turbidity waters might benefit from PACs with higher basicity, which can produce larger and faster-settling flocs.

2. Target Application: The intended use of the treated water is critical. For drinking water treatment, specific purity standards and regulatory compliance are paramount, often requiring PACs with very low levels of impurities. For industrial wastewater treatment, the focus might be on removing specific pollutants or achieving a certain level of clarity for discharge or reuse. Applications in industries like papermaking or oil refining may have unique requirements that dictate the choice of PAC.

3. Basicity of PAC: PAC products are often characterized by their basicity, which refers to the ratio of hydroxyl groups to aluminum ions. Higher basicity generally indicates a higher degree of polymerization and a greater charge density. This can lead to more efficient coagulation and flocculation, particularly in challenging water conditions. Understanding the basicity of different PAC grades is key to matching the product to the water matrix.

4. Physical Form and Handling: PAC is available in both powder and liquid forms. Powdered PAC requires dissolution before use, which adds a step to the process but can be advantageous for storage and transportation. Liquid PAC offers convenience in dosing, especially for automated systems. The choice often depends on the client's existing infrastructure and operational preferences for handling industrial chemicals.

5. Cost-Effectiveness Analysis: While all PAC products offer cost advantages over traditional coagulants, a thorough analysis considering dosage rates, performance under specific conditions, and the impact on downstream processes is important. NINGBO INNO PHARMCHEM CO.,LTD. can assist clients in performing these analyses to ensure they select the most economically viable and technically effective PAC solution.
