PRODUCT INTRODUCTION
Eco-friendly Decolorant is a high-performance water treatment chemical designed to remove color from dyeing, printing, textile, papermaking and industrial wastewater. It adopts an optimized formula with low environmental impact, effectively decomposing and precipitating colored pollutants through coagulation, adsorption and charge neutralization mechanisms.
Compared with traditional decolorizing chemicals, this product shows better decolorization efficiency, wider pH adaptability and lower sludge generation. It can reduce chroma, suspended solids and part of COD in one treatment stage, and helps wastewater meet discharge standards more stably. It is suitable for both intermittent and continuous dosing systems.
The Eco-friendly Decolorant is available in powder and liquid forms. It dissolves quickly in clean water and forms stable working solution. It can be used together with flocculants, coagulants and pH regulators after compatibility confirmation. Proper dosage control will not increase salinity or secondary pollution obviously.
Every batch is tested for decolorization efficiency, pH value, solubility, solid content and sludge yield before shipment. We provide complete export documents including COA, TDS and SDS for quality traceability and customs compliance. Our technical team can recommend suitable grade and dosage according to your water quality, dye composition and effluent standard.

USAGE NOTES
Dosage Control:
The recommended dosage is 50–200 mg/L depending on wastewater quality. Start from lower dosage and increase gradually based on jar test results.

COMMON PROBLEMS IN DOWNSTREAM PRODUCTION
Color Removal Still Poor After Dosing
Wrong grade, insufficient dosage, unsuitable pH or complex dye composition may reduce decolorization efficiency.
Solution: Re-test wastewater quality, select matching grade, adjust dosage and optimize pH condition.
Flocs Are Small and Settling Slow
Poor flocculation performance, low polymer bridging or improper stirring may lead to loose flocs.
Solution: Combine with suitable flocculant, adjust dosing sequence and optimize stirring intensity.
Sludge Volume Increases Obviously
Overdosing or unsuitable formula may produce excess flocs and increase sludge yield.
Solution: Reduce dosage, switch to low-sludge grade and verify optimal point by jar test.
Decolorization Effect Unstable
Dye composition change, pH fluctuation or temperature variation may affect treatment result.
Solution: Monitor wastewater quality frequently, re-calibrate formula and adjust dosage accordingly.
Product Caking During Storage
Moisture absorption and improper storage may cause powder caking and difficult dissolution.
Solution: Keep sealed in dry condition, avoid high humidity, sieve before dissolution if needed.
Compatibility Problem with Other Chemicals
Direct mixing with some coagulants, flocculants or oxidants may cause precipitation or reduced efficiency.
Solution: Conduct jar test before full use, separate dosing points and adjust chemical order.
Customs Detention Due to Mismatched Documents
Incorrect HS code or SDS information triggers inspection and detention at destination ports.
Solution: Confirm destination country regulations before order. Standard export data: HS Code 3824.9999, non-hazardous. We supply consistent full-set SDS / COA documents.
Batch Performance Deviation
Wastewater quality fluctuation, inconsistent dissolving concentration and unstable dosing flow cause variation.
Solution: Standardize Eco-friendly Decolorant grade and dosage, calibrate metering pump and test each incoming batch.
