摘要:
A clarifier basin (429) is provided with upflow channels (453) for removing solids from liquid that flows up the channels. The channels are defined by pairs of spaced sheets (449) and are provided at their upper ends with flap members (443) that releasably close the channels. Each sheet is provided with three-dimensional members (118), such as spherical bubbles or ellipsoids, that are in a two-dimensional array or regular pattern. The sheets are positioned closely adjacent each other so that the 3D members on one sheet nest with the 3D members of the adjacent sheet to form interstices that collect the solids. The sheets are movable to enlarge the interstices so that air bubbles can flow up a selected channel and remove the solids for collection by a reservoir located above the selected channel. An air supply (201) and the reservoir traverse the channels to remove the solids from the channels on a one-by-one basis.

In one embodiment apparatus is disclosed for taking up and paying out first and second ends of an endless loop of tape (37,39,41) that has an intermediate section. A first reel (57) connected to the first end carries a first coil (64) of the tape. The first coil (64) extends from the first reel (57) and is normally self-expanding and unwinding so as to unwind itself from the first reel (57). A second reel (58) is connected to the second end for carrying a second coil (65) of the tape (37,39,41). The second coil (65) extends from the second reel (58) and is normally self-expanding so as to unwind itself from the second reel (58). A drum (59) supports both of the first and second reels (57,58) for rotation in the same direction. Pulleys (44,45,49,50,47,48) guide the intermediate section of the tape from the first reel (57) to the second reel (58) for moving a sludge collector (33A,33B). When the drum (59) is rotated in a first rotary direction, the first coil (64) tends to self-unwind from the first reel (57) and the second coil (65) is wound up on the second reel (58) to move the intermediate section of the tape and the sludge collector. Upon rotation of the drum (59) in a second rotary direction, the second coil (65) tends to self-unwind from the second reel (58) to apply tension to the tape (37,39,41) and the first coil (64) is wound up on the first reel (57) to move the intermediate section of the tape and the sludge collector (33A,33B).

摘要:
La cuve de clarification décrite (429) est pourvue de canaux à écoulement ascendant (453) servant à extraire des particules solides d'un liquide ayant un écoulement montant dans les canaux. Les canaux sont définis par des paires de lames espacées (449) et comportent à leurs extrémités supérieures des rabats (443) qui ferment les canaux de façon amovible. Chaque lame est munie d'éléments tridimensionnels (118), qui sont constitués par des bulles sphériques ou par des ellipsoïdes et qui sont disposés en structure régulière ou en réseau bidimensionnel. Les lames sont placées étroitement adjacentes les unes des autres, de sorte que les éléments tridimensionnels d'une lame s'emboîtent dans les éléments tridimensionnels de la lame adjacente pour former des interstices servant à recueillir les particules solides. Les lames sont mobiles, ce qui permet d'agrandir les interstices. Ainsi, les bulles d'air peuvent monter dans un canal sélectionné et extraire les particules solides, lesquelles sont recueillies par un réservoir situé au-dessus du canal sélectionné. Une amenée d'air (201) et le réservoir traversent les canaux, ce qui permet d'extraire individuellement des canaux les particules solides.
