Abstract

The objective of this study is to develop an aeration nozzle, capable of getting high dissolved oxygen (DO) and control of DO, which is simple in structure and will not be choked with floating materials such as roots and sand. The relationship between the value of DO and the factors affecting the aeration performance of the nozzle was examined. The high value of DO was gained when the length of bubbles was about 90% of the total length of the nozzle. The air intake port diameter was an important factor to control the value of DO.
