Abstract
A lamella separation apparatus comprising a liquid receiving tank having a lamella plate assembly supported therein defining flow passages between adjacent lamella plates. The lamella plates have a generally rectangular inclined settling surface and rear surface and a leg portion extending perpendicular to an upper portion of the rear surface along the entire width thereof. The leg portion extends between adjacent lamella plates in closing relationship to the corresponding flow passage therebetween. A plurality of horizontally spaced orifices extend through the lamella plates at an elevation a small distance below the elevation of the leg portion in communication with a corresponding flow passage for directed clarified liquid therethrough into an area above the lamella plate assembly. The orifices are sized so as to create a small pressure drop across the orifices to ensure substantially equal flow distribution through the flow passages. The lamella plates have spacer lugs at the lower and central portions thereof and are individually removable from the lamella plate assembly.
