Jiangsu Hengfeng has become a professional production and research and development base for water treatment chemicals and oilfield chemicals in China.

  • Industrial Wastewater Management: Practical Treatment Guide

    Industrial wastewater management becomes expensive very quickly when a treatment line is built instead of actual water behavior. As a manufacturer and supplier of polyacrylamide, we usually see the same pattern: a plant focuses on one visible problem such as poor settling or high sludge volume, but the real issue is that charge balance, solids characteristics, oil content, and mixing conditions a...

  • Troubleshooting Wet-End Chemistry: Foaming, Deposits & Poor Drainage in Paper Mills

    The wet end of a paper machine is where chemistry, physics, and mechanical engineering converge under relentless time pressure. It is also where the majority of runnability problems originate. Foaming in the headbox, sticky deposits on forming fabrics and press felts, and sluggish drainage on the wire — these three issues account for a disproportionate share of unplanned downtime, sheet breaks, a...

  • How Water Quality (pH, Salinity, SS) Impacts PAM Performance

    Polyacrylamide (PAM) is widely trusted across municipal sewage treatment, industrial wastewater management, mining, and oilfield operations for its powerful flocculation and sedimentation capabilities. Yet even the highest-grade PAM will underperform if the fundamental properties of the water being treated are not properly accounted for. Three variables — pH, salinity, and suspended solids (SS) c...

  • 5 Things You Must Know Before Importing Polyacrylamide from China

    Polyacrylamide (PAM) is one of the most widely used industrial polymers in the world, applied in wastewater treatment, oil and gas extraction, mining, and papermaking. China produces the majority of the global supply — and for good reason: cost efficiency, large-scale manufacturing infrastructure, and rapidly improving quality standards have made Chinese manufacturers a go-to source for buyers ac...
