Operating principle
Dissolved Air Flotation is mainly for solid-liquid or liquid-liquid separation. Large sum of micro bubbles produced by dissolving and releasing system adhere to solid or liquid particles with same density as waste water to make the whole float to the surface thus achieve the aim of solid-liquid or liquid-liquid separation. 

Application: 

1. papermaking waste water treatment and fiber recovery
2. printing and dyeing waste water treatment
3. electroplating waste water treatment, including all kinds of heavy metal ion.
4. oil waste water treatment
5. tannery waste water treatment
6. chemical waste water treatment
7. paint waste water treatment
8. food waste water treatment
9. surface water including algae treatment.
10. water with lower temperature, lower turbidity and more algae treatment.
