Selecting the correct Polyacrylamide (PAM) polyelectrolyte is crucial for achieving optimal results in various industrial applications. The effectiveness of PAM hinges on its specific properties, namely its charge type (anionic, cationic, or non-ionic) and molecular weight. Understanding these characteristics, along with the specific requirements of your process, will guide you towards the most efficient and cost-effective solution. NINGBO INNO PHARMCHEM CO.,LTD. offers a comprehensive range of PAM products to meet these diverse industrial demands.

The charge density of Polyacrylamide is a primary determinant of its performance. Anionic Polyacrylamide (APAM) carries a negative charge and is typically used for flocculating positively charged particles, making it ideal for applications such as raw water purification, industrial wastewater treatment, and mining. Its ability to bridge particles and form large flocs is highly valued in solid-liquid separation processes.

Cationic Polyacrylamide (CPAM), conversely, possesses a positive charge. It is particularly effective in treating wastewater that contains negatively charged suspended solids, such as those found in sludge dewatering, paper manufacturing, and textile dyeing. The cationic charge enhances the attraction to negatively charged particles, leading to stronger floc formation and better dewatering efficiency. When considering purchasing PAM, the nature of the contaminants in your system will heavily influence the choice between APAM and CPAM.

Non-ionic Polyacrylamide (NPAM) carries no net charge and is typically used in applications where the suspended particles are neutral or when a very mild flocculation action is required. It can be effective in specific scenarios like silt suspension or in combination with other charged flocculants. While less common than its charged counterparts, NPAM serves a critical role in specialized industrial treatments.

Molecular weight is another critical parameter. Polyacrylamides are available in a wide range of molecular weights, typically from a few million to over twenty million. Higher molecular weight polymers generally form stronger and larger flocs, leading to improved settling and filtration characteristics. However, the viscosity of the solution also increases with molecular weight, which can impact handling and dosing. NINGBO INNO PHARMCHEM CO.,LTD. provides PAM with molecular weights ranging from 5 to 22 million, offering flexibility to match process requirements.

When deciding to buy Polyacrylamide, consider the following: the pH of the water, the nature and concentration of suspended solids, the required settling or dewatering rate, and the presence of other chemical additives.
