<p>PURPOSE: A floatation tank for rotatably injecting nano size bubbles is provided to improve the efficiency of floc elimination by generating plenty of ultramicro bubbles. CONSTITUTION: A floatation tank for rotatably injecting nano size bubbles includes a circulating water distributing pipe(113), an injecting nozzle, and a rotary plate. The tank further includes a vibration rubber plate and a friction plate. A pressurizing pump circulates a part of processing water discharged to an outlet into circulating water. An air compressor supplies compressed air. The circulating water outlet transfers air dissolved circulating water to a circulating water inlet. A groove is formed at the center of the vibration rubber plate. The circulating water passes through the groove.</p> |
