Bubble Column Flocculation

Bubble Column Flocculation

The primary mechanism for flocculation in a bubble column device is orthokinesis thus the rate of flocculation is proportional to the velocity gradient and concentration of flocculable particles the velocity gradient in a bubble column may be estimated using g u2p1g181 where g is the velocity gradient ug is the superficial gas velocity p1 181 and g are the liquid density viscosity
