How Do We Treat Textile Printing And Dyeing Wastewater Treatment

  • Pre-treatment: removes coarse solids, adjusts pH, and equalizes the wastewater flow for subsequent treatment stages
  • Biological treatment: utilizes microorganisms to break down organic pollutants and remove nutrients (nitrogen and phosphorus)
  • Advanced oxidation processes (AOPs): generate highly reactive hydroxyl radicals to degrade recalcitrant organic compounds and persistent dyes
  • Membrane filtration: removes suspended solids, colloids, and large molecular weight organics, producing high-quality effluent
  • Activated carbon adsorption: removes residual organics, color, and odor-causing compounds, polishing the treated water
  • Sludge handling: dewatering and stabilizing the sludge generated during the treatment process for safe disposal or reuse

Process

CHENENG is China’s top company that makes wastewater treatment systems for textile factories. We help clean water used in making wool sweaters, cotton shirts, and plastic-like fabrics. Our machines have these great features:

✓ Save money
✓ Easy to use
✓ Good for nature
✓ Lasts a long time
✓ Adds oxygen back to water
✓ Uses special chemicals to clean hot/cold water systems and power plant water
✓ Can work in new or old factories

Challenges

Making textiles needs good wastewater treatment. Factories use lots of water to make fabrics, yarns, and finish cloth products. When they work with many different chemicals and dyes, this creates dirty water that needs to be cleaned.

Solutions

At Wuxi Cheneng Environmental Engineering Equipment Co., Ltd., we provide comprehensive and efficient solutions for the complex wastewater challenges faced by the textile printing and dyeing industry.

Our treatment system is specially engineered to address the high concentration of organic pollutants, color, and chemical residues typically found in textile wastewater. Among our core technologies, the Dissolved Air Flotation (DAF) System plays a pivotal role.

Key Solution Components:

  • DAF System: Our DAF System is designed to effectively remove suspended solids, oils, and high chromaticity contaminants. By injecting microbubbles into the water, our DAF units cause impurities to float to the surface for easy removal. This process significantly reduces the load on subsequent biological treatment stages and ensures stable system performance.

  • Automatic Dosing Devices: Accurate and automated chemical dosing ensures optimal coagulation and flocculation, enhancing the performance of the DAF process and reducing chemical waste.

  • Sludge Dewatering Equipment: After treatment, our Sludge Dewatering Machines efficiently reduce sludge volume, simplifying disposal and lowering operational costs.

  • Customized System Integration: Each solution is tailored based on the client’s influent characteristics, required discharge standards, and available space. Our engineers provide on-site support for system design, installation, and commissioning.

With years of experience in wastewater treatment for textile industries, Cheneng ensures that every system we deliver is high-performing, energy-efficient, and built to last.

Why Choose Cheneng for Textile Wastewater Treatment?
