Description
This type of decanter is a development of the solid bowl where separation occurs in two stages. In the first stage clarification and sedimentation take place as in a solid bowl decanter centrifuge. The second stage allows further dewatering as the solids are conveyed over a perforated screen section. In addition, the solids can be washed whilst on the screen and, if required, the wash liquor can be collected separately.
