Polyamine Coagulant for Food Processing Wastewater DAF Pretreatment
Product Overview
Meat and poultry wastewater varies sharply between production, washdown and sanitation periods. Blood, protein, tissue fines, fat and detergents create a complex DAF feed. Polyamine can improve initial charge neutralization, while a selected PAM increases floc size and bubble capture.
Designed for pretreatment after effective screening and free-fat control. It does not disinfect wastewater or replace biological treatment for dissolved organic load.
Application Advantages
- Conditions fine protein and tissue particles for flotation.
- Supports denser, more skimmable DAF float.
- Can reduce solids shock to downstream biological treatment.
- Flexible liquid dosing suits variable processing schedules.

Recommended Treatment Approach
Separate coarse solids at the source and equalize wastewater where feasible. Run tests on production and sanitation samples because detergent carryover can change coagulation. Dose polyamine first, then add PAM at lower shear and evaluate actual DAF flotation.
Dosage Optimization
Optimize for TSS, FOG, COD, float solids and chemical cost. Include sludge dewatering behavior because a program that removes more solids but creates watery float may raise total disposal cost.
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
It can help remove blood-associated suspended and colloidal material, but performance varies with dilution, pH and cleaning chemicals.
Caustic, acid and surfactant cleaners change pH and particle stability, so a dose optimized for production wastewater may not work during cleanup.
No. Polyamine is a coagulation chemical, not a disinfectant. Required hygienic or discharge controls must be provided separately.

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.
