Lead time depends on lane, grade & volume
Higher solids capture
Optimized bridging reduces fines carryover and improves overflow/filtrate clarity.
Lower operating cost
Correct grade selection can reduce chemical consumption and stabilize separation performance.
Performance is system-specific. Jar tests and site trials are recommended to confirm grade, injection point, and dose window.
What it is
Anionic polymer flocculants are long-chain, water-soluble polymers (commonly anionic polyacrylamide, PAM) used to aggregate suspended solids into larger flocs for improved separation. They are widely applied in clarification and thickening where bridging is the main mechanism—especially in mineral and inorganic solids systems. In many treatment programs, they work alongside an upstream coagulant (e.g., ferric or aluminum salts) that conditions the particles, followed by polymer flocculation to accelerate settling and improve overflow clarity.
Typical use cases
- Clarifiers and settlers (process water, wastewater, recycle loops)
- Thickeners (mineral slurries, tailings, concentrate streams)
- Sand wash / aggregate washing fines capture
- Industrial effluent solids separation (program-dependent)
- Paper & pulp / mineral processing clarification applications
Procurement-ready: specify the slurry
Tell us your solids type, solids %, equipment, and whether a coagulant is used—then we can align charge density, molecular weight, and preparation format.
Note: Overdosing can cause restabilization or cloudy overflow. Optimization should target a stable dose window with consistent mixing and injection.
Applications
Operationally relevant applications and what each program is trying to achieve.
Clarification
Reduces suspended solids in overflow/effluent by forming larger, faster-settling flocs.
Thickening
Improves settling rate and underflow density in thickeners to stabilize downstream handling.
Fines capture
Captures fine particles in aggregate washing and recycle loops to reduce turbidity and losses.
Dosing & preparation (practical notes)
Dose is site-specific and depends on solids, chemistry, and mixing. Optimize on settling rate, overflow clarity, and underflow density.
Powder: ensure controlled wetting, correct solution concentration, and hydration/aging to reach full activity.
Emulsion: requires proper inversion and dilution equipment for consistent activation and stable dosing.
Minimize excessive shear after floc formation—optimize injection point and mixing intensity to protect floc structure.
If you can share a quick jar-test note (dose vs settling/clarity), we can shortlist the best charge density and MW faster.

Storage & handling (typical)
Good handling protects performance and reduces operational variability.
Powder storage
Keep dry, sealed, and away from humidity to prevent caking. Palletized supply available.
Emulsion storage
Avoid freezing/overheating; keep containers closed. Follow TDS for mixing and stability guidance.
Make-down
Use controlled wetting/inversion and correct dilution to avoid fisheyes and ensure consistent activation.
Specifications may vary depending on batch, origin, and packaging selection. Final acceptance criteria should follow your site targets and trial results.
FAQ
Quick answers for operations and procurement.
What does “anionic” mean in polymer flocculants?
“Anionic” indicates the polymer carries negatively charged functional groups. In practice, selection depends on solids and chemistry—anionic grades are frequently used in mineral and inorganic solids systems where bridging and floc strength are key.
Do I need a coagulant before the polymer?
Not always. Many programs use a coagulant (ferric/aluminum salts, lime, etc.) to condition particles and then polymer for floc growth and settling. We can support either approach based on your water analysis and targets.
What causes cloudy overflow or fines carryover?
Common causes include under/overdosing, poor mixing, incorrect injection point, or a grade mismatch (charge/MW). Stabilizing the preparation system and refining dose often resolves it.
Powder vs emulsion—what’s the main difference?
Powders require proper wetting and hydration/aging. Emulsions need correct inversion and dilution equipment. Both can perform well when prepared correctly; choose based on site utilities and operational preference.
What documents can you provide?
SDS, TDS, and COA are available on request. If you have site compliance requirements or a vendor questionnaire, include it in your inquiry.
Can you supply multiple grades?
Yes. Many sites trial two or three candidate grades to find the best dose window and stability. We can propose options across charge density and molecular weight for evaluation.
