2) Disk centrifuge = The disk-type centrifuge consists of a vertical stack of thin disks in the shape of cones. The principle is using centrifugal force which in removing solids from liquids. The denser solids or liquids which are subjected to these forces move outwards towards the rotating bowl wall while the less dense fluids moves towards the center. The disc stacks increase the surface settling area which speeds up the separation process. 

3) Chamber bowl = contains number of tubular bowls arranged co-axially. The fluid travel inside the chamber and the centrifugal force pushes the heavier substance to the walls of the chamber and the lighter substance remain at the center while the solids settle onto the outer wall of each chamber.

4) Scroll decanter centrifuge = Consists of a solid cylindrical bowl rotating at high speed, a scroll rotating at the same axis with a slightly different speed. Liquid and suspended solids are fed along the center line to a distribution room within the bowl and then accelerated into the bowl by centrifugal force through the feeding point. This centrifugal force then causes the suspended solids to settle and accumulate at the bowl wall.

5) Basket centrifuge = They have a perforated wall and cylindrical tubular rotor. The outer wall of a basket centrifuge consists of a fine mesh screen or a series of screens with the finer mesh screens supported by the heavier coarse screen, which in turn is supported by the bowl. The liquid passes through the screen, and the particles too large to pass through the screen are deposited.
