In order to put the sonochemical processes of wastewater treatment and material processing in practical use, it is necessary to enhance sonochemical reaction rate and develop a large sonoreactor. In this study, we develop the rectangular sonoreactor and the effects of liquid height and flow on sonochemical reaction rate are investigated. The rectangular sonoreactor was made of stainless steel with glass window and the inner dimension were 120 cm in length, 10 cm in width and 30 cm in height. The ten PZT transducers with 78 mm in the diameter were set in line in the reactor. The sample was 0.1 M of potassium iodide (KI). The sample was flowed by using liquid pump. The I_3^- generation rate increased with decreasing liquid height. The observation of luminol solution indicated that the sonochemical reaction field with high intensity was observed near liquid surface. The I_3^- generation rate became higher by liquid flow. It was considered that the sonochemical reaction field became larger due to enhancement of supply of nuclei cavity.
