Anionic Polyacrylamide PAM Polyelectrolyte for Paper Mill White Water Recovery
Product Introduction
Paper mills generate large volumes of white water containing fine fibers, fillers, starch, clay, and suspended solids during the paper production process. Without efficient recovery systems, valuable raw materials are lost and wastewater loads increase significantly.
Bluwat Blufloc Anionic Polyacrylamide is specially designed to improve white water clarification and fiber recovery efficiency in paper mills. The polymer rapidly flocculates suspended solids and fine fibers into larger flocs, allowing faster sedimentation, flotation, and filtration.
According to the Blufloc Polyacrylamide Technical Data Sheet, the product is available in anionic, cationic, and nonionic grades with different molecular weights and charge densities for various industrial applications including paper making and water recovery.
Main Benefits of White Water Recovery PAM
Improve Fiber Recovery Efficiency
Fine fibers lost in white water systems represent direct raw material loss for paper mills.
Blufloc Anionic PAM helps recover:
- Fine cellulose fibers
- Fillers
- Calcium carbonate
- Clay particles
- Starch residues
This significantly improves overall paper production yield.
Reduce Suspended Solids in White Water
The polymer rapidly destabilizes suspended particles and forms dense flocs for efficient clarification.
Benefits include:
- Lower turbidity
- Cleaner circulation water
- Improved filtration efficiency
- Better process stability
Support Water Recycling Systems
Modern paper mills aim to reduce freshwater consumption and improve sustainability.
Using PAM in white water treatment systems helps:
- Increase water reuse rate
- Reduce wastewater discharge
- Lower freshwater demand
- Improve closed-loop water system operation
Improve DAF and Clarification Performance
Anionic polyacrylamide works efficiently with:
- Dissolved Air Flotation systems
- Sedimentation tanks
- Disc filters
- Save-all systems
- Fiber recovery units
The product improves separation efficiency while reducing sludge volume.
