The role of polyacrylamide (PAM) in modern water treatment cannot be overstated. As a leading PAM chemical manufacturer, we understand that the molecular weight, ionic character, and degree of hydrolysis dictate its efficiency across various applications. Cationic PAM is primarily used for sludge dewatering in municipal and industrial biological treatment plants, where its positive charge neutralizes negatively charged sludge particles, promoting dense floc formation. Anionic PAM excels in mineral processing, coal washing, and drinking water clarification due to its high molecular weight and bridging capabilities. Nonionic PAM is chosen for sensitive environments requiring minimal residual charge, while amphoteric forms offer adaptability to variable influent chemistries.
