Factors influence the flotation process

Key design variables in dissolved air flotation system controlling efficiency of removal 
are as follows:

1. Gas input rate and volume of gas entrained per unit volume of liquid;

2. Bubble-size distribution and degree of dispersion;

3. Surface properties of the suspended matter;

4. Hydraulic design of the flotation chamber;

5. Concentration and type of dissolved materials;

6. Concentration and type of suspended matter and oils;

7. Chemicals added;

8. Temperature;

9. Residence time;

10. Recycle ratio;

11. pH.
