The feedstock enters the decanter through feed tube and flows into the centrifugation space through the distributor. The conveyor screw transports the solids to the solids discharge. The level of the liquid can be adjusted by fitting regulating rings or disks of the required inner diameter. Separation of the two liquid phases takes place in the separation zone, whereby the light phase flows towards the bowl axis, and the heavy phase towards the bowl wall.
Regarding the discharge of the liquid phases 3-Phase Separating Decanters are available in numerous designs. Liquid phases can be discharged by gravity or under pressure by centripetal pump.
In the case of a 3-Phase Separating Decanter with centripetal pump for the light phase and gravity discharge of the heavy phase, the light liquid phase leaves the centrifugation space over an exchangeable regulating ring and is discharged under pressure by the centripetal pump. At the same time, the heavy liquid phase is discharged under gravity through exchangeable regulating tubes.
Another technical variant is the case of a 3-Phase Separating Decanter with centripetal pump for the heavy phase and gravity discharge of the light phase. The choice of the appropriate design depends on the product to be separated and the lay-out of the customer installation.

Innovating for impact: shaping better solutions for customers
Industrial production is being asked to use fewer resources, become smarter and keep equipment productive for longer. At GEA, that is changing how innovation happens: engineering, customer insight, digital expertise and service come together earlier – when a solution can still be shaped at its core.
