ABSTRACT:
The invention relates to a method of clarifying and/or thickening a solution containing solids i.e. a slurry, and the apparatus for accomplishing this. Using the method and apparatus of the present invention, the slurry to be fed into the clarification or thickening apparatus is distributed evenly into the slurry already in the tank. It is characteristic of the clarification tank now developed that the displacement capacity of the raking system in the tank is the same from the edges of the tank up to the centre. The displacement capacity is measured as being the same as the underflow discharge capacity from the centre of the tank. The displacement capacity can be determined to be the same using rake displacement plates of different heights, according to the distance of the displacement plates from the rake shaft and the number of plates rotating on the same ring-like cross-section.
