Polyamine Coagulant for Rubber Latex Wastewater Treatment
Latex is intentionally stabilized during production, so wastewater may resist conventional settling. Polyamine provides positive charge to collapse part of this electrostatic stability. After coagulation, a compatible PAM can build larger flocs for flotation, settling or sludge handling.
Applicable to natural or synthetic latex wastewater after concentrated product recovery. Formulation surfactants, ammonia, pH and polymer type determine the required treatment sequence.
- Directly targets negatively charged latex particles.
- Can reduce persistent milky turbidity after source recovery.
- Supports downstream PAM flocculation and solid-liquid separation.
- May be combined with pH adjustment or PAC when needed.

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.
Test fresh wastewater because latex can change during storage. Evaluate native pH and controlled pH conditions, then screen polyamine doses under rapid mixing. Add PAM only after visible destabilization and assess both supernatant clarity and recovered solids.
Avoid overdosing, which can reverse surface charge and restabilize fine particles. Use turbidity, charge response, solids recovery and sludge dewatering as optimization criteria.
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.
Why does latex wastewater stay milky?
Surfactants and surface charge keep very small rubber particles dispersed. Effective treatment must first destabilize those particles.
Is acid coagulation still needed?
Some latex streams respond to pH adjustment, while others can be treated with polymer or a combined program. Compare options on safety, cost and sludge quality.
Can recovered rubber be reused?
That depends on contamination and product-quality requirements. Treatment performance does not by itself establish that recovered solids are suitable for reuse.
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.
