  • 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...

  • Papermaking Filter Aid Guide: Faster Drainage, Cleaner White Water

    In a paper mill, “papermaking filter aid” usually refers to wet-end and short-circulation additives that help water separate from fiber/filler more efficiently while keeping valuable solids in the sheet. In practice, an effective filter aid program improves drainage on the wire, stabilizes vacuum performance, and clarifies white water for better system cleanliness. For most grades, polymeric filte...

  • Flocculant for Aluminium Oxide: Key Industries & Best Practices

    What industry uses flocculant for aluminium oxide? When we ask “what industry uses flocculant for aluminium oxide,” they are usually dealing with one of two realities: (1) aluminium oxide (Al2O3) or alumina hydrate solids that must be separated from liquor or water, or (2) fine mineral/oxide particulates that behave like colloids and refuse to settle without polymer bridging. In practice, floccul...
