Low Dosage Polyamine Coagulant for High Turbidity Wastewater
Product Overview
High turbidity does not always mean high polymer demand. When turbidity is driven by fine negatively charged particles, a small dose of strong cationic coagulant may sharply reduce stability. The correct dose depends on particle surface area and charge, not simply the turbidity number.
Suitable for industrial runoff, mineral fines, process wash water and other high-turbidity streams that respond to charge neutralization. Very high settleable solids should first be removed by screening, grit separation or primary settling.
Application Advantages
- Strong charge response at comparatively low active-polymer dose.
- Fast dispersion and easy liquid metering.
- Can reduce the load on downstream PAM flocculation.
- Supports compact treatment programs where storage is limited.

Recommended Treatment Approach
Remove coarse settleable solids, then prepare a logarithmic dose series rather than small changes around one guessed dose. Observe initial destabilization, add PAM if required, and evaluate settling or flotation under plant-relevant conditions.
Dosage Optimization
The phrase low dosage is a treatment objective, not a guaranteed numerical claim. Report dose as active product per treated volume and compare total cost, sludge and water quality across all candidates.
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
No. Turbidity measures light scattering, not charge demand. Particle size, mineralogy and surface chemistry are more important for polymer demand.
Charge reversal can restabilize particles, producing cloudy water or fragile floc. Use a wide jar-test range to locate the true optimum.
Physical removal is usually more economical for coarse or rapidly settling solids. Chemicals are most valuable for fine and colloidal fractions.
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.
