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. The operating principle of a decanter centrifuge is based on separation via buoyancy.
Naturally, a component with a higher density would fall to the bottom of a mixture, while the less dense component would be suspended above it. A decanter centrifuge increases the rate of settling using continuous rotation, producing a force equivalent to between 1000 and 4000 G's.
This reduces the settling time of the components by a large magnitude, whereby mixtures previously having to take hours to settle can be settled in a matter of seconds using a decanter centrifuge.
This form of separation enables rapid and controllable results. Solid Bowl and Screen Bowl Decanter Centrifuges are the two most common types of decanter centrifuge used in the industry.
