NINGBO INNO PHARMCHEM CO.,LTD. offers a range of high-performance polyacrylamide (PAM) flocculants, essential for efficient water and wastewater treatment. To maximize their benefits, understanding how to use these versatile polymers correctly is key. Effective application involves careful consideration of product form, preparation, dosage, and the specific characteristics of the water being treated.

PAM is typically supplied as a white powder or granules. Before application, it must be dissolved in water to form a solution. It is crucial to use clean water, preferably at room temperature. While dissolving is possible at temperatures below 5°C, the process is slow. Temperatures above 40°C should be avoided as they can accelerate polymer degradation, reducing efficacy. Tap water is generally suitable, but water with high salinity, strong acidity, or strong alkalinity should be avoided as these conditions can negatively impact PAM's performance and stability.

The preparation of the PAM solution involves slowly adding the powder to water under constant agitation. This prevents clumping and ensures uniform dissolution. The concentration of the prepared solution typically ranges from 0.1% to 0.5%. Once prepared, the PAM solution can be directly added to the wastewater stream. The effectiveness of PAM is significantly influenced by its addition point and timing within the treatment process. For optimal flocculation, it is often recommended to introduce PAM after initial coagulation has occurred and during the latter stages of the flocculation reaction, allowing sufficient time for bridging and floc formation.

When choosing the right type of PAM – whether anionic, cationic, or non-ionic – consider the nature of the contaminants. For wastewater with positively charged suspended particles, anionic PAM is highly effective. Cationic PAM is preferred for sludge dewatering and in municipal wastewater treatment. Non-ionic PAM is ideal for applications in neutral or slightly acidic conditions. Understanding the properties of your water, including pH, turbidity, and the type of contaminants, is essential for selecting the most suitable PAM.
