Abstract
PURPOSE: To contrive to reduce the operation cost by assembling a floating and separating part and a vacuum type dehydrating part of the titled apparatus applied to the float concn. of an activated sludge or the like into a single apparatus to dehydrate frothes efficiently.
CONSTITUTION: A float separation tank and a froth dehydrating part provided to one corner of an upper part of this float separation tank and having an inclined filter surface are equipped and the separating tank and a dehydrator tank are integrated. The liquid to be treated and the pressurized air dissolving liquid are flowed into the float separation tank 4 respectively from introducing pipe 1 and 2 through a rectifier plate 3 and a clarified water after float separation is exhausted from an outflow pipe 5. The froth subjected to the floating and concn. is conveyed to the dehydrating part 6 while scraped by a sludge gathering knife 11 of a rotary link belt 12 and dehydrated under vacuum on the inclined filter surface 7 comprising a porous plate or a filter cloth and the filter cake is dropped into a filter cake tank 16 from a filter surface 7.
