A decanter centrifuge separates solid materials from liquids in slurry and therefore plays an important role in wastewater treatment, chemical, oil and food processing industries.
A decanter centrifuge employs the same principles of gravitational force. However, the process is expedited through the use of continuous rotation. In fact, rotation provides many times the normal gravitational force, reducing the time required for separation.
A decanter centrifuge is essentially a bowl tube that rotates at an extremely high speed. The bowl tube is equipped with an internal conveyor which moves in the same direction but at a different velocity. The slurry is inserted into the decanter. The bowl rotates at high speeds to induce gravitational forces. High speed rotation separates the solid material from the liquid. The solid material is discharged through a nozzle. The purified liquid is released from a separate output.
