Polyacrylamide (PAM) is a synthetic polymer that has become an indispensable tool in the field of water treatment. Its unique properties as a high molecular weight polyelectrolyte make it exceptionally effective in facilitating the removal of impurities from water, whether for potable use or industrial discharge. NINGBO INNO PHARMCHEM CO.,LTD. provides a range of PAM products designed for optimal performance in diverse water treatment scenarios.

The core mechanism by which PAM functions in water treatment is flocculation. Water sources often contain finely dispersed particles, colloids, and suspended solids that are too small or too stable to settle out easily. When PAM is introduced into the water, its long polymer chains adsorb onto the surfaces of these particles. Through a process called bridging, a single PAM molecule can link multiple particles together, forming larger aggregates known as flocs. These flocs are denser and larger, causing them to settle out of the water column much more rapidly and efficiently than the individual particles.

PAM exists in several forms, primarily classified by their ionic charge: anionic, cationic, and non-ionic. Anionic PAM carries a negative charge, cationic PAM carries a positive charge, and non-ionic PAM has a neutral charge. The choice of PAM type often depends on the nature of the contaminants in the water. For instance, positively charged particles in industrial wastewater might be best treated with anionic PAM, while negatively charged impurities, such as those found in municipal sewage sludge, are often effectively treated with cationic PAM.

The benefits of using PAM in water treatment are significant. It offers a high level of purification efficiency, even at low dosages, making it a cost-effective solution. PAM is also relatively stable across a range of pH conditions, providing flexibility in application. Furthermore, it helps to reduce the volume of sludge produced by the treatment process, which simplifies disposal and lowers associated costs.

Beyond water purification, PAM finds applications in other areas such as mineral processing, oil recovery, and paper manufacturing, highlighting its versatility. However, its role in ensuring the safety and clarity of our water resources remains its most critical contribution. By understanding the properties and selecting the appropriate type of PAM, industries can achieve superior water quality, meet regulatory standards, and contribute to a healthier environment. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supplying high-quality PAM products and providing the technical expertise needed to optimize water treatment processes.
