Choosing the Right Cationic Polyacrylamide for Efficient Sludge Dewatering

Industry News
mia@cnycchem.com

In a paper mill in Southeast Asia, operators struggled with acidic wastewater and unstable sludge settling performance. After switching to our 8050 and 8120 cationic series, the sludge formed larger flocs, filtration speed improved, and the plate-and-frame filter press operated more efficiently.

For chemical plants, textile factories, and power plants dealing with more complex industrial wastewater, models such as 8200 and 8300 provide stronger flocculation performance and better separation results for belt filter presses and plate filter presses.

As wastewater treatment standards become stricter worldwide, municipal sewage plants and food processing industries require higher-performance sludge dewatering solutions. Our 8190, 8400, 8500, and 8600 series are widely used in applications including:

  • Municipal wastewater treatment
  • Beverage and juice sludge dewatering
  • Brewery and alcohol plant wastewater
  • Starch and pharmaceutical wastewater
  • Livestock and slaughterhouse wastewater

For more demanding environments such as landfill leachate and river sludge treatment, high-ionicity models like 8650 and 8700 deliver excellent flocculation performance and are suitable for centrifuges, screw presses, belt presses, and plate filter presses.

Different industries generate different sludge characteristics — and selecting the correct ionic degree is the key to achieving stable treatment performance while reducing chemical consumption and operational costs.

Whether you are operating a paper mill, municipal wastewater plant, food factory, or industrial treatment system, choosing the right cationic polyacrylamide can significantly improve dewatering efficiency and treatment performance.

Our technical team can recommend the most suitable model based on your wastewater type, sludge characteristics, and equipment.
