White Liquor Clarifiers
Green liquor and lime are combined in the slaker, and then transferred to a series of vessels called causticizers. The result of this process is a slurry of white liquor and lime mud. In order to be used in the digesters to break down wood chips, the white liquor must be separated from the lime mud. The first step in this process is to purify the white liquor by allowing the mud to settle in a sedimentation clarifier. This course will identify and describe the major components of a white liquor clarifier.
