Disc centrifuges for clarifying and separating liquids
From algae harvesting to beer clarification and protein extraction: If you want to separate or purify liquids or remove ultra-fine particles you need powerful and robust separators. With their enormous centrifugal acceleration of up to over 12,000 g, Flottweg separators are real purification and clarification all-rounders.
Where decanter centrifuges reach their performance limits, separators come into play. Thanks to their higher speeds, they are able to process liquids optimally. Do you want to separate finest solid particles from a liquid? Then a clarifying separator (2-phase separation) is the right solution. Do you need to separate liquid phases of different densities while simultaneously separating solids? Then a purification separator (3-phase separator) is required.
In addition, Flottweg's know-how as a system partner is of great importance, as separators are often the last stage in an extensive separation process. They are often combined with an upstream decanter or Tricanter®. Flottweg customizes the process to the customer's requirements and also finds the best possible separator solution that can be integrated into existing piping and plant systems.

Flottweg disc stack separators are available in two basic designs:
How the Flottweg separator works
The product to be separated is fed into the rotating drum through a central infeed pipe. A distributor inside the machine evenly distributes and gently accelerates the incoming liquid to the full operating speed of the bowl, ensuring controlled and low-shear product handling.
Within the disk stack, the product is divided into numerous thin layers, creating a large effective separation surface and significantly improving separation efficiency.
Under high centrifugal forces, the solid particles migrate toward the periphery of the bowl, where they accumulate.
The collected solids are periodically discharged by a hydraulic system at the bottom of the bowl without interrupting operation. The clarified liquid phase is continuously removed by a centripetal pump and discharged under pressure for further processing.

The Little Atlantique Brewery in Nantes, France uses the AC1700 separator from Flottweg for beer clarification.
Passion for fresh beer, brewing craftsmanship and creativity – this is what the French brewery Little Atlantique in Nantes stands for. Together with the use of a Flottweg separator and the integrated Flottweg recipe control, the brewery has made its processes more efficient and saved costs.
Features of the Separator
Centripetal Pump
The centripetal pump ensures optimum discharge of the clarified liquids from the centrifuge. It discharges the clarified liquid under pressure from the separator bowl and prevents the product from foaming.
Lubrication
A lubrication circulation system ensures fully automatic lubrication of the bowl spindle bearings. It lubricates the bearings regularly with an optimum oil quantity. This enables precise and speed-independent lubrication.
Disc stack
The actual splitting up of the liquid mixture takes place in the separator bowl disc stack. The disc stack consists of a large number of vertically arranged conical individual discs. The disc stack increases the clarifying area in the separator bowl and thereby the separation efficiency.
InGo
The Flottweg separators are controlled by our InGo operating philosophy. It enables optimum interaction of all process components and shows all important process parameters at a glance.
Drive
The compact spindle drive with belt transmission ensures low-vibration, well-damped operation, enables continuously variable speed control and smooth start-up, and helps reduce energy consumption and component wear for reliable, efficient performance.
