Clarification
Improves settling and filtration by forming stronger, larger flocs from fine suspended solids.
Product Water Treatment
Polymer Flocculant (Nonionic)
Nonionic polymer flocculant used to improve clarification, thickening, and dewatering where charge-neutral bridging and stable performance across variable water chemistry is preferred.
✓ Nonionic PAM (charge-neutral)
✓ Powder or emulsion (per site)
✓ Low-ppm dosing (trial-optimized)
✓ Bags / drums / IBC + SDS/COA/TDS
Formats: powder / emulsion (project-dependent)
Packaging: bags / drums / IBC (as applicable)
Documentation: SDS / COA / TDS on request
Dewatering
Supports better cake solids and drainage on belt presses, centrifuges, and filter presses (grade dependent).
Process stability
Nonionic bridging can be robust under variable salinity/pH conditions compared with strongly charged programs.
Best results come from jar testing and plant trials to match molecular weight, make-down concentration, and shear tolerance to your equipment.
What it is
Nonionic polymer flocculants are long-chain water-soluble polymers commonly based on polyacrylamide (PAM). They work primarily through bridging: polymer chains adsorb onto particle surfaces and link fines together into larger, faster-settling flocs. Nonionic grades are often chosen when a charge-neutral program is preferred, when raw water chemistry varies, or where compatibility with certain coagulants is needed.
Where it adds value
- Clarifiers: turbidity reduction and faster settling
- DAF/floatation support (process-dependent)
- Sludge thickening and dewatering (belt press / centrifuge / filter press)
- Industrial effluent polishing and solids capture
- Mining/mineral processing: tailings settling and water recovery (grade dependent)
Grade selection is process-driven
We align molecular weight, dissolution/inversion behavior, and shear tolerance to your solids and equipment to reduce overdosing risk and improve clarity/cake solids.
Note: Polymer performance depends on the full program (coagulant choice, pH, mixing energy, and contact time). Always validate using jar tests or trials.
Applications
Typical usage patterns and practical targets. We align grade and format to your process and handling setup.
Clarification & settling
Helps capture fines, improve overflow clarity, and increase settling rate in clarifiers and thickeners.
Sludge dewatering
Improves drainage and floc strength on belt presses/centrifuges to support higher cake solids and stable operation.
Tailings & process water
Supports tailings settling and water recovery in mineral circuits (grade and shear tolerance are critical).
Dosing & preparation (practical)
Many programs dose in low-ppm range (often ~0.1–10 mg/L as product), then optimize via jar tests and plant trials.
Powder make-down: use controlled wetting to avoid fisheyes; allow hydration/aging before dosing (time depends on polymer grade and concentration).
Emulsion: requires proper inversion and dilution; match to your preparation skid and mixing energy.
Avoid excessive shear in pumps/valves where floc strength is critical—optimize injection point and mixing intensity.
Site variables matter: solids type, salinity, pH, temperature, and coagulant program can shift the best-performing molecular weight and preparation strategy.

Storage & handling (typical)
Good handling protects performance and reduces downtime.
Powder storage
Keep dry and sealed; prevent moisture pickup and caking. Palletized supply available.
Emulsion storage
Protect from freezing/overheating; keep containers closed. Mix gently if recommended on TDS.
Preparation
Use correct make-down concentration and dilution. Avoid over-shear to preserve floc performance.
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 procurement and operations.
Why choose a nonionic flocculant?
Nonionic polymers can be effective where charge-neutral bridging is desired, or where water chemistry varies. They may be used alone or as part of a coagulant + polymer program depending on solids and targets.
How do I determine the best grade?
Jar testing or plant trials are the most reliable. We typically match molecular weight and preparation method to your solids, equipment shear, temperature, and coagulant program.
What common issues reduce performance?
Improper make-down (fisheyes), insufficient aging, overdosing, wrong injection point, or excessive shear can reduce clarity and floc strength. Stable dilution and controlled mixing usually improve results.
Can it work without a coagulant?
Sometimes. In many clarifications, a coagulant (PAC/ferric/alum) neutralizes charge and the polymer builds floc. The best approach depends on your solids type and target clarity.
What packaging and documents are available?
Powder is commonly supplied in 25 kg bags or big bags. Emulsions can be supplied in drums or IBC. SDS, TDS, and COA are available on request.
Is it suitable for drinking water?
Some applications may require specific approvals and site acceptance criteria. Share your use case and compliance requirements so we can advise on suitable sourcing lanes.
