Decanter Centrifuge
A decanter centrifuge, also known as a horizontal solid bowl centrifuge, is designed to continuously separate solid materials from liquids in a suspension. It can also separate two liquid phases while simultaneously removing solids. Decanter centrifuges are widely used for continuous solid-liquid separation, clarification, and fine particle classification.
Based on their application, decanter centrifuges are generally categorized into three types:
1. Clarifying Decanter Centrifuge
2. Separating Decanter Centrifuge
3. Classifying Decanter Centrifuge
Clarifying Decanter Centrifuge
Dewatering processing for maximum concentration of solids, or concentrating for the concentration of solids.

Advantages of the Decanter Centrifuge
Continuous production, closed operation, high degree of automation.
Good for greasy sludges. The Decanter Centrifuge is excellent for dewatering or separation of fats, oils and greases.
Large capacity in small space. The Centrifuge can offer a large solids handling capacity in a very small space. This is advantageous in large plants.
With lower capture or high polymer dosage rate, can sometimes achieve higher cake solids than the belt press filter. One reason for this is the large amount of shearing as the sludge is moved through the machine, and the temperature increase in the sludge from the power energy dissipated. Increasing temperature improves dewatering. High G force centrifuges can create cell lysis and this releases extra liquid, but these liquids are high in odour, some of which is retained.
