Product Water Treatment
Coagulant Aid (PolyDADMAC)
High-charge cationic polymer used as a coagulant aid to improve turbidity reduction, strengthen floc formation, and support stable clarification and filtration performance in municipal and industrial treatment systems.
Grades: multiple actives/viscosities (per inquiry)
Packaging: drums / IBC / bulk (as applicable)
Documentation: SDS / COA / TDS on request
Why PolyDADMAC is used
PolyDADMAC provides strong cationic charge to neutralize negatively charged colloids and fine particles. It is often used as a primary coagulant in specific applications or as a coagulant aid alongside inorganic coagulants (PAC, ACH, alum, ferric), where operators aim to improve floc strength, reduce turbidity carryover, and stabilize performance under variable conditions. Final selection and dose are confirmed via jar tests and plant trials.
- Helps capture fines and colloids for better clarification
- Can improve filter performance and reduce turbidity spikes (system dependent)
- Useful when raw water changes or when coagulant optimization is needed

Where PolyDADMAC typically adds value
PolyDADMAC is often evaluated when operators want tighter turbidity control, stronger flocs, reduced carryover, or improved downstream filtration. It may also help reduce overall coagulant demand in some programs—final economics depend on the system and must be confirmed through testing.
- Fine particle capture and turbidity polishing
- Floc strengthening for settling/DAF stability
- Filtration support (filter run time and carryover control)
Availability, lead time, and best-fit grade depend on your process, target performance, order size, and destination lane.
Applications
PolyDADMAC is used in coagulation/clarification programs to improve particle destabilization and floc formation. It is commonly applied as a coagulant aid with inorganic coagulants or, in some cases, as a primary organic coagulant (application dependent).
- Drinking water clarification and turbidity control (system dependent)
- Wastewater and industrial effluent clarification (fine solids capture)
- Pretreatment upstream of filters or membranes (case dependent)
- Process water clarification and reuse loops (application dependent)
How it works in practice
As a cationic polymer, PolyDADMAC helps neutralize negatively charged particles and can bridge fines into larger flocs. Performance is influenced by mixing energy, contact time, pH/alkalinity, organics, and the presence of inorganic coagulants. Jar testing is the standard method to identify dose, best dosing point, and any complementary chemistry (e.g., PAC/ACH plus polymer).
- Dosing point matters (rapid mix vs. post-coagulant aid)
- Overdosing can reduce performance—dose optimization is critical
- Best results are set by jar tests and confirmed by plant trials

Typical dosing guidance (starting points)
Dosing depends on water chemistry and the coagulant program. The ranges below are indicative only and must be confirmed by jar tests and plant trials.
| Use case | Typical role | Indicative range* | Notes |
|---|---|---|---|
| Drinking water clarification | Coagulant aid (with PAC/ACH/alum) | ~0.1–2.0 mg/L (as product) | Dose depends on turbidity/organics and coagulant program |
| Industrial effluent clarification | Fines capture / floc strengthening | ~0.5–10 mg/L (as product) | Solids load and separation method drive dose |
| Pretreatment before filtration/membranes | Colloid control | Case dependent | Confirm compatibility with the downstream separation system |
*Illustrative starting ranges only. Final dosing must be set by jar testing, trials, and your operating standards.
Handling & storage (summary)
Store in closed containers away from excessive heat and direct sunlight. Avoid contamination. Follow SDS guidance for PPE and spill response. For dosing, many sites dilute to improve feed control—confirm dilution water quality and dosing practice to avoid performance loss.
- Use compatible tanks, piping, and metering pumps for viscous liquids
- Prevent freezing/overheating based on local conditions and grade
- Follow SDS for handling, PPE, and disposal practices
Specifications may vary depending on batch, origin, and packaging selection. The offer and COA are the controlling documents.
FAQ
Common questions from operators and procurement teams.
Is PolyDADMAC a replacement for PAC/alum?
Sometimes it is used as a primary organic coagulant, but most plants use it as a coagulant aid with inorganic coagulants. Best choice depends on raw water, targets, and economics—confirm via jar tests and trials.
How do I pick the right grade?
Grade selection is typically based on active content, viscosity (handling), and performance in jar tests for turbidity/settling/DAF/filtration. Share your constraints and we’ll align a suitable option.
Can overdosing cause issues?
Yes. With cationic polymers, overdosing can restabilize particles or worsen clarity. Dose optimization and dosing point selection are critical.
Do you provide SDS/COA/TDS?
Yes. SDS and COA are standard on request; TDS and specific QC parameters can be included depending on your requirements.
Is it compatible with chlorine/oxidizers?
Compatibility depends on concentration, contact time, and your treatment sequence. Share your dosing layout so we can advise on practical handling considerations.
Do you support trial quantities?
Many customers start with trial volumes to validate performance. Tell us your plan and we’ll propose a practical packaging option.
