3-Phase Decanter Centrifuge is used for Solids / Oil / Water separation, and based on GN Technical Team's experience, the separated oil from decanter has about 3% content of moisture + impurities. And if the fed sludge can be Solid < 10 % and Particle size < 2mm, there would be better performance. The Oil can be re-sale for Industry application, and water can be recycled in the system or discharged to city sewer system. And Decanter Cake can be used for Fertilizer or animal feed.

Here is working principle about 3-Phase Decanter Centrifuge

The centrifuge is composed of two rotors, one drum (2), and the other is screw (3). When the drum rotates at high speed, the slurry in the drum rotates with the drum and is subjected to centrifugal force. This centrifugal force is many times larger than gravity, so the solid particles will be separated from the liquid and settled on the inner wall of the rotating drum from the axis of the centrifuge drum. The screw rotates at a speed lower than that of the rotating drum and pushes the deposited solid particles to the slag outlet (1). The differential speed of the outer rotating drum and the screw (affecting the slag pushing speed) depends on the transmission ratio of the differential and its speed. The heavy-duty liquid has centrifugal force and is divided into two layers. The heavy phase layer is drawn against the wall of the drum by the centripetal pump (4) and discharged from the heavy phase outlet (6). The light phase layer is close to the spiral end, thrown out by centrifugal force from the overflow, and then discharged from the light phase outlet (5). The whole work is continuously completed between the closed upper and lower shells.
