NINGBO INNO PHARMCHEM CO.,LTD. provides Poly Aluminium Chloride (PAC), a highly effective coagulant for water treatment. To maximize its performance, understanding the correct usage and application methods is crucial. This guide details the essential steps and considerations for effectively employing PAC in your water treatment processes.

PAC can typically be used in two primary ways: direct addition of the solid product or preparation of a solution for application. Direct addition involves introducing the solid PAC directly into the water body to be treated, using dosages determined by jar tests. This method is straightforward but requires careful distribution to ensure uniform mixing.

The preferred method for many applications involves preparing a PAC solution. This typically involves dissolving the PAC powder in water. While heating the water can aid dissolution, it’s important to add the PAC slowly while stirring continuously until it is fully dissolved. The resulting solution is then applied to the water being treated. It is critical to note that PAC solutions are generally best used within 24 hours of preparation to maintain their efficacy. Properly preparing and applying PAC is key to achieving the best results in water purification PAC processes.

Effective PAC usage also necessitates adherence to several key principles. Performing a 'jar test' is fundamental. This laboratory test helps determine the optimal PAC dosage and the most suitable PAC type for specific water conditions. Without a jar test, you might use too much or too little chemical, leading to inefficient treatment or increased costs. Controlling the pH of the water is also vital; PAC works best within specific pH ranges, and adjustments may be needed depending on the source water's characteristics.

Proper mixing and stirring are essential to ensure PAC fully contacts the impurities in the water, facilitating floc formation. This can be achieved through mechanical agitation or aeration. Additionally, water temperature can influence PAC's effectiveness; while it performs well in cooler temperatures, very low temperatures may slow down the coagulation process. Paying attention to the dosing sequence, especially when used with other treatment agents, is also important; PAC is typically added before other agents like flocculants.

NINGBO INNO PHARMCHEM CO.,LTD. emphasizes these practices to ensure our clients achieve the best possible outcomes from their PAC applications. By following these guidelines for how to use Poly Aluminium Chloride, you can ensure efficient, effective, and reliable water treatment.
