Polyaluminum Chloride (PAC) is a highly effective chemical used in various water treatment applications. To ensure its optimal performance and safety, understanding proper storage and usage guidelines is crucial. As a leading manufacturer and supplier, we provide this comprehensive guide to help industrial users maximize the benefits of PAC.

Storage of Polyaluminum Chloride:

Proper storage of PAC is essential to maintain its efficacy and prevent degradation. PAC is typically supplied as a powder. It should be stored in a dry, cool, and well-ventilated place, away from direct sunlight and sources of heat. The packaging, usually durable bags, should be kept tightly sealed to prevent moisture absorption and caking. Moisture can lead to agglomeration, reducing the product's solubility and effectiveness. It is also advisable to store PAC away from incompatible materials, such as strong bases or reducing agents, to prevent hazardous reactions. Regular inspection of stored material for any signs of caking or discoloration is recommended. Adhering to these storage protocols ensures the product's shelf life, typically around two years, is maintained.

Usage of Polyaluminum Chloride:

PAC can be used in two primary ways: direct addition of the solid product or preparation of a solution for application. For direct addition, the optimal dosage, determined through jar tests specific to the water being treated, is added directly to the water body. This method is straightforward and efficient for many applications.

Alternatively, PAC can be prepared into a solution. For powder PAC, it's often recommended to dissolve it in water at a concentration of about 5-10%. Heating the water to boiling before slowly adding PAC and stirring continuously ensures complete dissolution. The prepared solution should ideally be used within 24 hours to maintain its stability and effectiveness. This pre-dissolution method can offer enhanced coagulation performance in some scenarios.

Key considerations during usage include controlling the pH of the water. PAC works best within a specific pH range, and adjustments may be necessary depending on the source water's acidity or alkalinity. Proper mixing and stirring are also vital; ensuring thorough contact between PAC and the contaminants promotes efficient floc formation. This typically involves rapid mixing for initial dispersion followed by slower, prolonged stirring to allow flocculation. The water temperature can also influence PAC's performance; cooler temperatures may require slightly longer reaction times.

For any industrial application, it is essential to perform jar tests to determine the optimal PAC dosage, pH conditions, and mixing parameters for your specific water source.
