Polyacrylamide (PAM) is a highly effective polymer that offers significant advantages in industrial processes, particularly in water treatment, oil recovery, and papermaking. However, to maximize its benefits and ensure cost-effectiveness, it is crucial to understand how to determine the correct dosage and apply it appropriately. NINGBO INNO PHARMCHEM CO.,LTD. provides comprehensive guidance to help clients select and utilize PAM products efficiently.

The optimal dosage of PAM is not a one-size-fits-all measure; it is highly dependent on the specific application and the characteristics of the material being treated. For polyacrylamide water treatment, factors such as the turbidity of the water, the type and concentration of suspended solids, and the pH value of the water body all influence the required dosage. Typically, dosages are determined through laboratory tests, such as jar tests, to identify the most effective concentration for flocculation and clarification. Generally, dosages for water treatment range from 0.03 to 0.4 mg/L, but precise adjustments are often necessary.

In applications like sludge dewatering, the type of sludge (e.g., municipal sewage sludge, industrial wastewater sludge) and the dewatering method (e.g., centrifugation, filter press) dictate the required PAM dosage. Cationic polyacrylamide (CPAM) is often used here, and its dosage is carefully calibrated to achieve optimal dewatering efficiency, resulting in drier sludge cakes and reduced disposal volumes. The correct application of cationic polyacrylamide sludge dewatering is critical for operational efficiency.

When considering PAM for oil recovery, such as in enhanced oil recovery polymer applications, dosage is determined by reservoir characteristics like permeability, temperature, and salinity, as well as the desired viscosity of the injection fluid. These factors influence the polymer's performance and longevity in the reservoir. Similarly, in the papermaking industry, the dosage of anionic polyacrylamide papermaking is optimized to balance retention, drainage, and paper strength improvements against cost.

NINGBO INNO PHARMCHEM CO.,LTD. emphasizes that proper preparation of PAM solutions is also key to effective application. The polymer should be dissolved in clean water at a controlled concentration (typically 0.1%-0.3%) before being introduced into the process. Adhering to recommended polymer flocculant dosage guidelines and preparation methods ensures that the PAM performs optimally, delivering the desired results efficiently and economically. By understanding these principles of polyacrylamide application, industries can harness the full potential of this versatile polymer.
