Chemical coagulation is a water and wastewater treatment process that uses chemical agents to destabilize suspended particles, colloids, and dissolved organic matter so they can be aggregated and removed from solution. ...

Floating flocs is remain one of the most persistent challenges in thickener performance. These buoyant aggregates form when gas bubbles—often from biological activity, chemical reactions, or mechanical entrainment—attac...

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 — ...

PAM (polyacrylamide) “not working suddenly” in most cases is due to 1) the polymer isn’t fully hydrated, 2) the dose is off by an order of magnitude, or 3) the solution is being destroyed by shear or incompatible water c...

Tissue paper is unforgiving. Unlike board or packaging grades, every flaw in fiber distribution shows up immediately — as thin spots, rough patches, or inconsistent basis weight. The root cause is almost always the same...

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 d...

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%. Tem...

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 ...

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-as...

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...

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:...

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 whe...
