Water Decoloring Agent for Dyeing, Printing, Paper and Ink Wastewater
High-efficiency cationic polymer decolorizing flocculant designed for colored industrial wastewater. It is normally evaluated by jar test and can be combined with PAC and PAM to improve coagulation, settling and final clarity.
When to use
Designed for wastewater where color is the main visible problem
The product page now follows a stronger B2B structure: problem, specifications, application, method, product combination and inquiry action.
Textile dyeing wastewater
Reactive, acid, disperse and mixed dye color reduction after biological or physicochemical treatment.
Printing and ink wastewater
Color removal support for high-chroma printing, ink and pigment wastewater streams.
Paper and chemical wastewater
Improves visible clarity when color and colloidal pollutants remain after pre-treatment.
PAC/PAM combined process
Use with coagulant and flocculant after jar-test confirmation to improve settling.
Quick specification
Buyer-ready product information
Clear tables improve SEO and make the page easier for importers, distributors and plant engineers to evaluate.
| Item | Reference information | Buyer note |
|---|---|---|
| Appearance | Light-color or colorless viscous liquid | Liquid product, easy to dilute and dose |
| pH value | 3-5 for 30% aqueous solution reference | Adjust wastewater pH according to jar-test result |
| Viscosity | 1-5s at 20°C reference | Confirm exact grade by inquiry |
| Content | >50% reference | Useful for dosage and cost comparison |
| Packaging | Drum / IBC options | Packaging confirmed before shipment |
Application method
Recommended evaluation process before order
Do not choose dosage only from theory. Use wastewater sample testing to match the agent, PAC and PAM correctly.
Take sample
Use representative wastewater from actual production.
Adjust pH
Test pH range and observe color removal difference.
Add decolorant
Stir quickly then slowly to promote reaction.
Add PAC/PAM
Combine when coagulation and settling are required.
Calculate ppm
Convert jar-test dosage to bulk treatment cost.
Product matching
Water decoloring agent is not a replacement for all chemicals
Leading competitor pages explain product combinations clearly. This table helps buyers understand how to select the right program.
| Chemical | Main role | When combined |
|---|---|---|
| Water Decoloring Agent | Breaks or neutralizes color-causing substances and improves visible color removal. | Core product for high-color wastewater. |
| PAC | Coagulates suspended solids and colloids, improves precipitation. | Used when flocs need better formation and settling. |
| PAM | Bridges flocs and accelerates settling / sludge separation. | Used after PAC or decoloring stage if floc strength is weak. |
