Abstract
Bubble size is an important factor in the flotation of oil and other contaminants from industrial wastewater. A novel cyclone flotation technique—the air-sparged hydrocyclone (ASH) technology—offers fine bubble size distribution required for the efficient removal of dispersed oil and has a specific capacity 100 times greater than conventional flotation equipment. In this investigation several systems containing dispersed oil were examined for treatment by ASH flotation. The influence of surfactant and flocculant concentrations, air and water flow rates and the overflow/underflow split were examined. The results of the testwork indicate that the cyclone flotation machine can be effectively used to remove oily particles if appropriate surface chemistry conditions are guaranteed.
