  • Industrial Wastewater Treatment: PAM Alone vs Coagulant + PAM

    In industrial wastewater treatment, the fastest way of using waste chemicals is choosing a “one-size-fits-all” program. As a PAM manufacturer and supplier, we, Jiangsu Hengfeng Fine Chemical Co., Ltd, typically suggest two workable paths: (1) using polyacrylamide (PAM) as the primary flocculant, or (2) building a two-step train with a coagulant followed by PAM. The right choice depends on how you...

  • How to Choose a Retention Aid for Different Paper Grades

    The most reliable approach is to match the retention system to the grade’s shear and ash/fines load: high-shear grades (tissue, high-speed printing) typically need a microparticle program, while moderate-shear, lower-ash grades often run well with a single cationic PAM (CPAM). If your furnish carries high anionic trash (recycled fiber, coated broke), start with charge control (coagulant) before p...

  • Polyacrylamide (PAM) for Municipal Drainage Erosion Control

    Polyacrylamide (PAM) can significantly reduce sediment in municipal drainage runoff when applied at the right rate and kept out of live water. Used as a temporary soil-binding/flocculation aid alongside BMPs (mulch, mats, check dams, inlet protection), PAM improves particle settling and reduces turbidity in conveyance features like swales, ditches, and outfall transitions. ▶ Where PAM works best ...

  • Cationic Polyacrylamide Flocculant Guide for Water Treatment

    Why Cationic Polyacrylamide Matters in Real Water Treatment Plants In many wastewater and industrial water treatment systems, separation performance is what determines operating cost. When flocs are weak, you pay twice: higher chemical consumption upstream and unstable sludge handling downstream. As a manufacturer and supplier of cationic polyacrylamide (CPAM), we see CPAM deliver the most value ...
