Polyaluminium Chloride (PAC) is a highly effective coagulant essential for various water treatment processes. However, to ensure its optimal performance and safety, proper usage and storage practices are paramount. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing clear guidance on these critical aspects. This article outlines how to use PAC effectively and the essential safety measures for its storage.

The utility of PAC in water purification stems from its robust coagulation and flocculation capabilities. When considering how to use PAC, it's important to note that it can be applied in two primary forms: as a solid powder or as a pre-prepared solution. The choice often depends on the scale of the operation and the available dosing equipment.

Direct Addition (Solid Form): For many applications, PAC powder can be added directly to the water body. The optimal dosage, determined through jar testing, is crucial for achieving the desired results. This method is convenient for smaller-scale operations or when specialized solution preparation equipment is not available. For those seeking to understand the best polyaluminium chloride dosage, jar tests are indispensable.

Solution Preparation: Alternatively, PAC can be dissolved in water to create a solution before application. This process typically involves slowly adding PAC to heated water while stirring continuously until it is fully dissolved. The prepared solution should ideally be used within 24 hours to maintain its efficacy. While this method involves an extra step, it often leads to more consistent and effective dispersion of the coagulant in the water body, enhancing its performance in various polyaluminium chloride applications.

Regardless of the application method, controlling the pH of the water is vital. PAC functions best within a specific pH range, and adjustments may be necessary for acidic or alkaline waters to maximize its coagulation effect. Proper mixing and stirring are also critical to ensure PAC thoroughly contacts suspended solids and colloids, facilitating the formation of larger flocs that settle easily.

When it comes to how to store polyaluminium chloride, safety and product integrity are the main considerations. PAC should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and heat sources. Keeping the containers tightly sealed is essential to prevent moisture absorption, which can lead to caking and degradation of the product. Storing PAC separately from incompatible substances, such as strong acids or bases, is crucial to avoid hazardous reactions.

Key storage precautions include:

  • Moisture Prevention: Protect PAC from humidity to prevent caking and maintain its free-flowing properties.
  • Temperature Control: Avoid prolonged exposure to high temperatures, which can affect product performance.
  • Container Integrity: Ensure containers are properly sealed and regularly inspected for any signs of damage.
  • Segregation: Store PAC away from chemicals with which it could react dangerously.

Safety during handling is also paramount. Personnel working with PAC should wear appropriate Personal Protective Equipment (PPE), including gloves, eye protection, and respiratory masks, especially when handling the powder form. Avoiding inhalation of dust or fumes and preventing skin contact are key safety protocols.
