Cationic
Medium-Low Charge
High MW
EmeraldFloc™ C20
A medium-low-charge cationic grade for sludge thickening and industrial effluent, where mineral or mixed solids dominate.
- Good thickening of mixed and mineral-rich sludges
- Economical on lightly loaded effluents
- High molecular weight for strong flocs
Where it works best
Recommended applications for EmeraldFloc™ C20. Not sure it fits your process? We will confirm the grade with a jar test on your own sample.
- Sludge thickening
- Industrial effluent treatment
- Gravity thickeners and DAF sludge
- Primary and mixed sludges
- Pre-thickening before dewatering

Dosing & handling
1. Prepare
Disperse the powder into water at 0.1–0.5 % with gentle mixing (below about 300 rpm) to avoid lumps and chain damage.
2. Age
Allow 30–60 minutes to dissolve fully, then dilute to about 0.025–0.1 % at the dosing point. Use the solution fresh.
3. Dose
Typical starting range: 3–8 kg/t of dry solids for sludge dewatering. Fine-tune with a jar test on your own sludge.
4. Store
Keep bags sealed, cool and dry. Spilled powder is very slippery when wet, so sweep up dry.
