Thickener or Thickener plant – COGEDE

Thickener or Thickener plant. Thickener is an equipment designed for solid liquid separation by gravity settling. The main goal of the thickener or of a thickener plant is to separate the solid liquid part from the slurry and to concentrate as much as possible the solid part in the bottom of the thickener in order to get from the top of the ...
