ABSTRACT:
A clarifier basin is provided with upflow channels for removing solids from liquid that flows up the channels. The channels are defined by pairs of spaced sheets. Each sheet is provided with three-dimensional (3D) members, such as spherical bubbles or ellipsoids, that are in a two-dimensional array or regular pattern. The sheets are positioned closely adjacent to 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 and the reservoir traverse the channels to remove the solids from the channels on a one-by-one basis.
