Frequently Asked Questions About Textile Dyes
What are textile dyes and chemicals? What are the types? Textile dyes and chemicals are a group of industrial chemicals used in textile pretreatment, dyeing, and finishing of textile products. The main types include: NaOH (mercerizing - alkalization), H₂O₂ (bleaching), Na₂SO₄ (dyeing auxiliary), NaCl (increasing dye absorption), PAC/FeCl₃ (wastewater treatment), acetic acid (pH neutralization).
Effluent treatment in the textile dyeing industry requires what chemicals to meet QCVN 13:2015?
To meet QCVN 13:2015/BTNMT:
(1) PAC or FeCl₃ for coagulation and decolorization.
(2) H₂O₂ or NaOCl for oxidation and decomposition of color groups.
(3) NaOH or HCl for pH adjustment to 6-9.
(4) Polymer as a coagulant aid to enhance flocculation and sedimentation.
PAC is more effective with reactive dyes and azo dyes at pH 6–8. FeCl₃ is suitable for disperse dyes and highly alkaline wastewater, with lower costs. Many factories combine both to optimize effectiveness and cost.
How is H₂O₂ used to decolorize textile dyeing wastewater? H₂O₂ 50% is combined with Fe²⁺ salt (FeSO₄) using the Fenton method at a pH of 3–4, generating OH• radicals that break down dye molecules. Dosage: 100–500 mg/L of H₂O₂, with an H₂O₂:Fe²⁺ ratio of 5:1–10:1. Decolorization efficiency: 80–95%.
NaOH for adjusting the pH of textile dyeing wastewater—what is the dosage? NaOH 32% dosing pump to raise the pH after the Fenton process. To raise the pH from 3 to 7, approximately 0.8–1.2 kg of NaOH 100% per cubic meter of wastewater is required. We recommend using an automatic metering pump combined with an inline pH sensor.
