The vertical decanters are based on the principle of static decantation and the natural precipitation of suspended solid particles. During decantation occurring inside Matec decanters, the solid particles (the mud) sink down to the bottom of the structure, while the clean water overflows into the drainage system at the top and it is discharged in a dedicated tank or pit (clean water tank).Thickener, Dorr - Big Chemical EncyclopediaThe simplest form of thickener is an ordinary settling tank arranged for the decantation of the clear liquid after settling. Nonmechanical, continuous settling tanks have conical bottoms from which thickened slurries high in solids are continuously discharged. The most widely used thickener is the mechanical type, of, which the Dorr is typical.
