  • Improving Thickener Performance Using Mineral Processing Flocculants

    Flocculants can improve thickener performance by 15-40% in underflow density and reduce settling time by 30-60% when properly selected and dosed. The right flocculant polymer type, molecular weight, and charge density directly impact particle aggregation, settling velocity, and clarification efficiency in mineral processing operations. Thickeners are critical unit operations in mineral processing...

  • How Temperature and Salinity Affect PAM Performance in Oilfields

    Polyacrylamide (PAM) polymers experience 30-70% viscosity loss when reservoir temperatures exceed 80°C, while high-salinity brines above 100,000 ppm total dissolved solids can reduce polymer effectiveness by 50-80%. Temperature and salinity critically degrade PAM viscosity and retention. These two factors represent the primary operational challenges in chemical enhanced oil recovery (EOR), as the...

  • 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...
