Effective solid-liquid separation is a critical challenge in many industrial processes, from wastewater treatment to mining and papermaking. Polyacrylamide (PAM) is a versatile polymer that plays a pivotal role in overcoming these challenges. NINGBO INNO PHARMCHEM CO.,LTD. offers this guide to help select the most suitable polyacrylamide for optimal solid liquid separation.

Polyacrylamides are broadly categorized into cationic, anionic, and non-ionic types, differentiated by the charge of their functional groups. The choice between these types largely depends on the nature of the suspended solids or colloids in the medium being treated.

Cationic polyacrylamide (CPAM) is characterized by its positive charge. This makes it highly effective in flocculating negatively charged particles. It is particularly well-known for its exceptional performance in sludge dewatering, where its positive charge attracts and destabilizes the negatively charged sludge particles, releasing trapped water. When considering high viscosity polyacrylamide wastewater treatment, CPAM is often the preferred choice for sludge-intensive applications.

Anionic polyacrylamide (APAM), conversely, carries a negative charge. It is effective in flocculating positively charged or neutral particles. While it can be used for general water clarification, its application might be more nuanced compared to CPAM in specific scenarios. Understanding the intricacies of anionic polyacrylamide water purification is key to its successful implementation.

Non-ionic polyacrylamide has no net charge and works primarily through bridging mechanisms. It is often used when electrostatic interactions are less critical or when specific properties are desired.

The selection process also involves considering the molecular weight and charge density of the polyacrylamide, as these parameters significantly influence its flocculation and separation efficiency. Crucially, the correct PAM flocculant dosage must be determined through testing. Over- or under-dosing can lead to suboptimal results. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the importance of trials to establish the ideal polyacrylamide dosage for specific applications, ensuring efficient water treatment and achieving the desired water purification.
