摘要：
The Dissolved Air Flotation (DAF) process has been widely used for removing suspended solids with low density in water. Size and distribution curve of microbubbles were evaluated at various pressure and nozzle condition. The change in nozzle size affects significantly on the microbubble rather than that in pressure. Also, at a fixed pressure, the treatment efficiency increased with the decrease in nozzle size or the increase in pressure. Finally, the change in pressure and nozzle size can be controlled microbubble diameter and improved treatment efficiency without the additional investment.
