Polyaluminum Chloride (PAC) is a highly effective coagulant in water treatment, but its performance hinges on proper usage and storage. For R&D scientists and plant operators, understanding these nuances is key to achieving optimal results and ensuring the longevity of their water treatment systems. As a leading polyaluminum chloride supplier, we are committed to sharing best practices.

Effective Usage Strategies for PAC:

PAC can be applied either directly as a solid or pre-configured into a solution. Direct addition involves adding the solid PAC according to the optimal dosage determined through jar tests. Alternatively, configuring a solution typically involves dissolving the PAC in water (often heated water for better dissolution) and using the solution within 24 hours for maximum efficacy. The choice between direct and solution methods often depends on the specific water characteristics and plant infrastructure.

Crucial to effective PAC application is controlling water quality parameters. Maintaining an appropriate pH is vital; adjust acidic water with alkaline substances and alkaline water with acidic substances to optimize coagulation. Proper mixing and stirring are also essential. Mechanical stirring or aeration for 1-3 minutes at 10-35 r/min ensures thorough contact between PAC and suspended solids, promoting robust floc formation. Be mindful of water temperature, as lower temperatures can slow down coagulation, while higher temperatures can enhance it. Always consider the dosing sequence; generally, PAC should be added before other treatment processes, and if used with coagulant aids, add PAC first.

Proper Storage for PAC Longevity:

To maintain the efficacy of your Polyaluminum Chloride, adherence to storage guidelines is critical. PAC is susceptible to moisture absorption, which can lead to caking and reduced performance. Therefore, store PAC in a dry, cool, well-ventilated place, ensuring containers are tightly sealed. Avoid direct contact with the ground and use moisture-proof materials for isolation. Keep PAC away from direct sunlight and high temperatures, as prolonged exposure can cause clumping. Regular inspection for agglomeration and prompt handling are recommended. Always follow safety regulations, wear protective gear, and ensure safety warning signs are visible in the storage area.
