Polyacrylamide Flocculant for Paper Mill Wastewater Clarification
Product Introduction
Paper manufacturing processes generate wastewater containing fine fibers, fillers, starch, ink residues, sizing chemicals, and suspended solids. Without efficient clarification treatment, paper mill effluent can lead to high COD, turbidity, sludge accumulation, and environmental discharge problems.
Bluwat Blufloc Polyacrylamide is specially designed to improve solid-liquid separation in paper mill wastewater treatment systems. The polymer forms large and dense flocs, accelerating sedimentation and clarification while improving sludge dewatering performance.
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 suitable for industrial wastewater treatment and paper making applications.
Main Advantages in Paper Wastewater Treatment
Rapid Suspended Solids Removal
Paper mill wastewater usually contains large amounts of suspended fibers and fillers. Blufloc PAM helps:
- Aggregate fine particles rapidly
- Form larger and denser flocs
- Improve settling speed
- Produce clearer supernatant water
This significantly improves wastewater clarification efficiency.
Reduce COD and Turbidity
The polymer improves removal of:
- Organic suspended solids
- Ink particles
- Fiber residues
- Coating materials
- Colloidal contaminants
This helps reduce COD and turbidity levels before discharge or biological treatment.
Improve Sludge Dewatering Performance
PAM strengthens sludge floc structure and improves water release during dewatering. Benefits include:
- Lower sludge moisture
- Reduced sludge disposal costs
- Improved filter press performance
- Better centrifuge efficiency
Support Water Recycling in Paper Mills
Modern paper mills increasingly recycle process water to reduce water consumption. Using Blufloc Polyacrylamide helps:
- Improve recycled water quality
- Reduce freshwater demand
- Lower wastewater discharge volume
- Improve overall sustainability
Typical Applications in Paper Mills
Primary Clarification
Used in primary settling systems to remove suspended solids and fibers.
Dissolved Air Flotation Systems
Improves flotation performance and enhances fiber separation efficiency.
Biological Treatment Pretreatment
Reduces suspended solids loading before aerobic or anaerobic treatment systems.
Sludge Thickening and Dewatering
Widely used before:
- Belt filter presses
- Screw presses
- Centrifuges
- Sludge thickening tanks
