The advantages of using tubular membrane separation technology in the treatment of printing and dyeing wastewater

1. Corrosion resistant to acid, alkali, and organic solvents, high temperature resistance, reversible regenerative cleaning, and long service life;

2. Surface active agents (Taikoo oil), NaOH, etc. in the recyclable wastewater can be reused for wiping plates;

3. No chemical steps such as flocculation and neutralization are required to reduce the generation of pollutants;

4. The system can be automatically controlled, with easy operation and low labor intensity;

5. The economic benefits of reusing permeate are significant, reducing production costs.
