ABSTRACT:
A filter bed clarifier comprising a tank (1), which consists of an upper, cylindrical part (2) and a lower, tapered part (3) and which is provided with a centrally disposed feed pipe (11) for the liquid to be clarified. The feed pipe has an outlet leading into the tank at the top opening (7) of the circulating/mixing cone (6) disposed in the lower, tapered part of the tank. The top opening is larger than the outlet opening (12) of the feed pipe so that the sludge being discharged from the feed pipe draws sediment flocs from the lower part of the bed, thus causing internal circulation of the sediment. The apparatus is especially suitable for clarifying green liquor.
