Polyamine Charge Neutralizer for Recycled Paper and Anionic Trash Control
Product Overview
Recycled-fiber systems receive variable dissolved and colloidal material from old corrugated containers, mixed office waste, coated broke and adhesives. These contaminants can consume cationic additives and destabilize wet-end performance. Polyamine targets charge demand before expensive functional polymers are added.
Useful where the mill observes fluctuating cationic demand, poor retention-aid response, deposits, foam associated with contaminants or unstable drainage after furnish changes.
Application Advantages
- Scavenges negatively charged dissolved and colloidal contaminants.
- Protects downstream retention and strength additives from unnecessary consumption.
- Supports steadier operation with variable recycled furnish.
- Can be controlled using charge measurements rather than dose alone.

Note: Values above describe the BLU AM product family. The final specification, viscosity, pH, shelf life and packaging must follow the selected grade's current TDS, SDS, COA and quotation.
Recommended Treatment Approach
Establish a baseline using filtrate cationic demand, turbidity, conductivity and machine performance. Screen different polyamine grades at low incremental doses. Select an addition point with adequate dispersion before retention PAM, starch or other cationic functional chemicals.
Dosage Optimization
The target is balanced charge, not maximum cationicity. Track retention, drainage, formation, deposits and additive consumption during the trial. Stop increasing dose when charge response or machine performance reaches a stable optimum.
Handling and Storage
Use corrosion-compatible metering equipment and prevent contamination between chemical tanks. If dilution is required, add product to clean water with moderate agitation and verify solution stability before continuous use. Keep containers sealed and follow the grade-specific SDS and TDS for personal protection, storage temperature and spill response.
Frequently Asked Questions
What is anionic trash?
It is a broad term for negatively charged dissolved and colloidal material that enters or accumulates in the papermaking system and interferes with cationic additives.
How is the optimum dose controlled?
Laboratory charge titration, streaming-current tools and carefully monitored machine trials are more reliable than a fixed dose based only on production tonnage.
Will polyamine remove stickies?
It can help neutralize or fix some colloidal contaminants, but it is not a universal stickies-control program. Screening, dispersants, talc or other strategies may still be required.
Information for Product Selection
For a useful sample recommendation, provide the industry and wastewater source, pH, temperature, turbidity or TSS, color or COD where relevant, current chemicals and doses, treatment flow, separator type, sludge issue and required outlet quality. Bluwat can then shortlist suitable BLU AM grades for comparative testing.
