Polyamine and PAC Combined Coagulation Chemical for Industrial Effluent
Product Overview
Polyamine and PAC do not perform identical jobs. Polyamine supplies concentrated cationic charge, while PAC contributes hydrolyzed aluminum species and can enmesh destabilized particles. A combined program can outperform either chemical alone when the wastewater contains both colloids and broader suspended or precipitated solids.
Useful for textile, paint, food, mineral and mixed industrial wastewater where one coagulant gives incomplete clarification or excessive sludge. Compatibility, residual aluminum and pH response should be checked.
Application Advantages
- Combines charge neutralization with inorganic coagulation mechanisms.
- Allows separate optimization of organic and inorganic dose.
- May improve treatment robustness across changing wastewater loads.
- Can reduce total cost even when two products are used.

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
Build a factorial jar test: several PAC levels crossed with several polyamine levels. Test both addition orders and keep mixing time consistent. Add PAM afterward only if larger flocs are needed for the separator. Record every dose and sequence, not just the best-looking jar.
Dosage Optimization
Compare total chemical cost, alkalinity consumption, sludge volume, clarified-water quality and dewatering. Avoid choosing the lowest PAC dose if polymer cost or residual performance makes the overall program less efficient.
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
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.
