<p><P>PROBLEM TO BE SOLVED: To provide a floatation separation apparatus for reducing the difference of the amount of inflowing water from each water collection opening of water collection members which can efficiently perform flotation separation treatment. <P>SOLUTION: The floatation separation apparatus includes: a floatation tank 1; a feed-well 10 for supplying raw water containing microbubbles in the floatation tank 1; a water collection pipe 11 having a plurality of water collection openings 12 provided on a lower part in the floatation tank 1; and treated water intake pipes 13 and 14 connected to the water collection pipe 11. The floatation separation apparatus is characterized in that at least one part of the water collection openings has a large diameter compared with a water collection opening in which the distance to the treated water intake pipes 13 or 14 is short. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
