Decanter centrifuge, horizontal solid bowl decanter centrifuge, separates continuously solid materials from liquids in the suspension, or to separate two liquid phases from each other simultaneous removal of solids. Decanter centrifuges have been widely used for continuous separation of suspended solids from liquids, clarification of solids, classification of fine particles, etc.
According to the purpose of use, decanter centrifuges can be divided into the following three categories, Clarifying Decanter Centrifuge, Separating Decanter Centrifuge, Classifying Decanter Centrifuge.
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.
