India is one of the world's largest producers of dyes and dye intermediates. These factories generate wastewater with extremely high color intensity, complex organic compounds, and elevated COD levels, making treatment difficult.
A dye intermediate manufacturer in India contacted Bluwat Chemicals seeking an efficient method to remove color from their chemical wastewater before biological treatment.
After analyzing the wastewater characteristics, Bluwat engineers conducted laboratory jar tests using a Decolorizing Agent + PAC + PAM treatment process.
Typical characteristics of dye intermediate wastewater include:
Extremely high color intensity
High COD concentration
Complex organic compounds
Poor biodegradability
Fine suspended particles and colloids
These characteristics make conventional coagulation insufficient for effective color removal.
The treatment process consists of three main steps.
The solid Bluwat Decolorizing Agent breaks down dye molecules and neutralizes color-causing compounds.
Polyaluminium Chloride (PAC) destabilizes suspended particles and promotes coagulation.
A small dosage of Polyacrylamide (PAM) helps form large flocs and accelerates sedimentation.
The jar test demonstrated significant color removal and improved sedimentation performance.
| Parameter | Before Treatment | After Treatment |
|---|---|---|
| Color (Pt-Co) | 3200 | <150 |
| COD (mg/L) | 2800 | 950 |
| Suspended Solids (mg/L) | 420 | <60 |
| Appearance | Dark brown | Light yellow / clear |
Within minutes, large flocs formed and the supernatant became significantly clearer.
Compared with traditional treatment methods, the Bluwat solution provides:
✔ High color removal efficiency
✔ Rapid floc formation
✔ Improved solid-liquid separation
✔ Lower treatment cost
✔ Better preparation for biological treatment
This treatment method is widely used in:
Dye intermediate manufacturing
Textile dyeing wastewater
Chemical production wastewater
Pigment and colorant industries
