More than 2.000 applications where Decanter Centrifuges are used to separate solid particles from a liquid or simultaneously separate two immiscible liquids and a solid are listed in relevant literature [1]. Of course a number of those applications are in a way exotic ones, are niche applications. Others are really volume applications, e.g. sludge thickening and dewatering, process-integrated recycling of valuable material and juice production. It is very obvious that the wide variety of applications implicate the need of significantly different Decanter Centrifuges in terms of individual features / design and size. On first sight, a Decanter Centrifuge may appear as a "simple" machine consisting of a rotating bowl and a conveyor rotating with differential speed. The "turbulent" journey, moving with the liquid flow from the inlet to the outlet will show us that a lot of thoughts must be spent to appropriately design and size this machine to reach the goal: Optimum performance in a specific application. Following the flow from entering into the feed-pipe down to the liquid outlet on one hand and the solids movement caused by the conveyor, we come across many critical aspects of state-of-the-art Decanter design and sizing e.g.: 1. Inlet (feed) zone design 2. Bowl design and sizing, 3. Conveyor design, 4. Liquid discharge design.
