  • 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 ...

  • Anionic or Cationic Polyacrylamide How to Choose and Dose

    Anionic Polyacrylamide and Cationic Polyacrylamide have different application area and cases. Normally, use anionic polyacrylamide when your suspended solids behave positively charged, and use cationic polyacrylamide when treating negatively charged sludge/organics. Confirm the choice with a quick jar test and then optimize the dose for fast settling (clarification) or low filtrate turbidity and s...

  • Polyacrylamide Stabilizer for Ore Pulp Prevent Settling & Coherence

    In mineral processing, slurry stability is not just a “handling” issue—it directly affects classification efficiency, flotation selectivity, pipeline reliability, and ultimately recovery. In this context, polyacrylamide acts as stabilizer to prevent the sediment and coherence of rock particle, helping keep the stability and mobility of ore pulp when and where you need it. At the same time, polyacr...
