    How a Thickener Works

    The Dorr washing thickener is of the multiple-tray type and is, in effect, a complete countercurrent decantation plant in a single compact unit It is adapted to the needs of the small chemical and metallurgical plants where a relatively small tonnage of finely divided solids must be washed free from a solution in a minimum space.
