Poly Aluminum Chloride (PAC) is a cornerstone chemical in modern water purification, renowned for its potent flocculation capabilities. To fully harness its benefits in industrial and municipal water treatment, understanding its correct usage and storage is crucial. This guide from NINGBO INNO PHARMCHEM CO.,LTD. aims to provide insights into optimizing PAC performance.

The application of Poly Aluminum Chloride typically involves two primary methods: direct addition of the solid product or preparation and use of a solution. Direct addition is often suitable for treating raw water sources, where the PAC powder is introduced directly. However, for more controlled and potentially enhanced results, preparing a PAC solution is recommended. This involves dissolving the powder in heated water with continuous stirring until fully dissolved. It's important to note that prepared solutions are generally best used within 24 hours to maintain their efficacy.

Key to effective PAC usage is the 'jar test'. This laboratory procedure helps determine the optimal product dosage and the best PAC type for specific water conditions. Sewage and wastewater often contain numerous variables, making a jar test indispensable for achieving efficient contaminant removal. Controlling the pH of the water is also vital; PAC functions best within a specific pH range, and adjustments may be necessary using alkaline or acidic substances depending on the initial water quality. Proper pH control ensures the maximum potential of the poly aluminum chloride is realized.

Effective mixing is another critical factor. Ensuring thorough contact between PAC and the suspended solids in the water is achieved through mechanical stirring or aeration. This promotes the formation of larger flocs, which are more easily removed through sedimentation and filtration. The stirring time and speed should be optimized based on the specific water being treated.

Storage of Poly Aluminum Chloride requires careful attention to maintain its quality and prevent degradation. PAC is hygroscopic, meaning it readily absorbs moisture, which can lead to caking and reduced effectiveness. Therefore, it must be stored in a dry, cool, and well-ventilated area, with containers kept tightly sealed. Protection from direct sunlight and high temperatures is also important, as prolonged exposure can cause clumping or affect performance. Storing PAC away from incompatible substances, such as strong acids and bases, is crucial for safety, preventing potentially hazardous reactions. Regular inspections of stored product for any signs of agglomeration or degradation are recommended to ensure stable performance. Adhering to these storage protocols for poly aluminum chloride will safeguard its chemical properties.

By implementing these best practices for usage and storage, industries can maximize the efficiency of Poly Aluminum Chloride, ensuring optimal water treatment outcomes.
