Lead time depends on lane, grade & volume
Cleaner filtrate
Correct dosing can improve capture and lower TSS in centrate/filtrate.
Lower polymer consumption
Proper grade selection reduces over-dosing, carryover, and instability under shear.
Performance is equipment- and sludge-specific. Jar tests and plant trials are recommended to finalize grade and starting dose.
What it is
Cationic polymer flocculants are long-chain water-soluble polymers (commonly cationic polyacrylamide, PAM) designed to condition sludge and improve solids capture. In dewatering, they help create stronger, drainable flocs by combining charge neutralization with polymer bridging. The “right” grade depends heavily on sludge origin (biological vs chemical), solids concentration, mixing energy, and the specific dewatering machine.
Typical use cases
- Municipal WWTP biosolids dewatering (belt press / centrifuge / screw press)
- Industrial wastewater sludge conditioning and solids separation
- Thickening prior to dewatering (gravity belt thickener, DAF solids)
- Paper & pulp / food / chemical process effluent sludge (process-dependent)
Procurement-ready: specify the process
Tell us your sludge type and dewatering equipment and we’ll align charge density, molecular weight, and preparation format for stable operation.
Note: Final dosing and grade choice should be validated with jar tests/bench tests and on-site optimization to avoid overdosing and carryover.
Applications
Operationally relevant applications and what each program is trying to achieve.
Sludge dewatering
Improves floc strength and drainage on belt presses, centrifuges, and screw presses—supporting higher cake solids and stable capture.
Thickening & conditioning
Enhances solids aggregation ahead of dewatering to reduce downstream load and improve polymer efficiency.
Solids separation
Aids solids capture in industrial wastewater where negatively charged fines respond well to cationic treatment.
Dosing & preparation (practical notes)
Dosing is site-specific. Many dewatering programs start with low-ppm ranges and refine based on cake solids, filtrate clarity, and polymer consumption.
Powder: requires controlled wetting, correct solution concentration, and hydration/aging to reach full performance.
Emulsion: needs proper inversion and dilution equipment for consistent activation and stable dosing.
Avoid excessive shear after floc formation—optimize injection point, mixing intensity, and pump selection to protect floc structure.
If you share a simple site trend (dose vs cake solids/centrate clarity), we can narrow grade selection faster and reduce trial time.

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.
Why is cationic polymer common for dewatering?
Many sludges carry a net negative charge and hold water strongly. Cationic polymers help neutralize charge, build stronger flocs, and improve drainage and capture on dewatering equipment.
What’s a typical starting dose?
Starting dose depends on sludge type, solids, and equipment. Most programs begin with a conservative low-ppm range and optimize based on cake solids, filtrate clarity, and polymer consumption.
What causes “overdosing” symptoms?
Overdosing can create slimy filtrate, poor drainage, and carryover. It may look like good floc formation but yields worse capture or lower cake solids. Trials help define the optimal window.
Can you supply both powder and emulsion?
Yes—availability depends on the sourcing lane and target grade. Tell us your preparation equipment and preferred packaging and we’ll align an appropriate format.
What documents are available?
SDS, TDS, and COA are available on request. If you have site compliance requirements, include them in your inquiry.
How fast can I switch grades?
Switching is typically straightforward, but the optimum dose and injection strategy may change. We recommend confirming performance with a short trial when changing charge density or molecular weight.
