Abstract
A means for obtaining high mass transfer efficiencies in surfactant laden wastewater treatment or process systems is disclosed. The present system employs ultrafine bubbles delivered into a high shear region such as in the draft tube or other containment volume of a mechanically agitated contacting system within which an impeller is placed, or in the venturi or divergent-convergent of a pumped loop within which gas-liquid contacting is carried out.
