PROBLEM TO BE SOLVED: To provide a pressure flotation device which can efficiently carry out floatation separation by enabling an efficient adhesion of fine bubbles to flocs, and preventing raw water discharged from a feed well from flowing outside a tank in a short path. SOLUTION: The pressure flotation device comprises a flotation tank consisting of a tank body 1 and an inner tank 2, and a top open feed well 10 disposed in the flotation tank. The raw water containing fine bubbles is fed into the lower part of the feed well 10 to rise in the feed well 10, and then introduced from the upper opening into the flotation tank. Ring baffles 20 are installed so as to surround the upper part of the feed well. COPYRIGHT: (C)2007,JPO&INPIT
