The sediment of dead leaves, the earth and sand cause the decrease in pondages and the water pollution in the lake or sea. To remove such sediments, an air lift pump attracts attention because it is hard to occlude by its simple structure. The bubble-jet-type air lift pump developed by Sadatomi can remove sediments which traditional air lift pump couldn't remove. The bubble jet generator which was also developed by Sadatomi is used in the bubble-jet-type air lift pump as an air supply. Using the bubble jet generator, it can forcibly levitate sludge accumulating on the bottom of lake or sea. Our purpose is to improve water quality and to increase the pondage with the bubble-jet-type air lift pump. In this paper, experimental results on the performance of the bubble-jet-type air lift pump are mainly reported.
