On the repair works of the large circulating tank, the paddle wheel of the fixed float typewas changed for that of movable float type and the thin steel plates such as the fixed and the movable current plates which were corroded with rust in the lapse of eight years were replacedby hard vinyl plastic plates.Then, the following two profits were obtained:1). The pulsatory motion of water flow, one of defects of the fixed float type paddle wheel,was not observed with the new movable float type and the velocity of water flow gave avalue 10~30% larger than that obtainable before.2). By using anti-corrosion materials as hard vinyl plastic, brass and cast iron for all apparatus exposed to the tank water,the occurrence of rust was stopped and the tank waterkeeps clear for many days.
