The Textile Wastewater Crisis
Textile effluents contain toxic dyes (reactive, disperse), heavy metals, surfactants, and high COD/BOD (often >2,000 mg/L). Traditional sedimentation fails to remove colloidal particles and soluble dyes, causing:
Environmental Damage: Aquatic toxicity and color pollution in rivers
Treatment Failures: Clogged membranes and disrupted biological processes
Compliance Risks: Violations of China’s GB 4287-2012, EU IPPC, and ZLD mandates.
Why Dissolved Air Flotation (DAF) Dominates Textile Pretreatment?
DAF technology injects 30-50µm microbubbles to lift contaminants unreachable by gravity:
Dye & Pigment Removal: Binds to cationic/anionic dyes, achieving >85% color reduction
Colloidal Solids Separation: Removes 90%+ SS and PVA sizing agents
Chemical Optimization: Coagulants (e.g., PAC) enhance heavy metal/floc removal
DAF-Driven Process: From Wastewater to Reuse
Chemical Conditioning: pH adjustment + flocculant dosing
DAF Unit: Microbubbles float dyes/fines → automated sludge skimming
Biological/AOP Polishing: Reduced load enables efficient bio-treatment & oxidation
Results: 70-90% COD removal, near-colorless effluent, 60% lower sludge volume vs. settling.
