In the classic separation process, solids are separated from a liquid, or two liquids of different densities are separated. But often both come together. This is exactly where the Tricanter^® from Flottweg is the right solution. It allows the continuous separation of three phases (solid-liquid-liquid) in a single process. This is attractive, for example, in the treatment of oily sludges, in starch production and in fat recovery.

More than 40 years ago, Flottweg developed the Tricanter^® to separate three phases in a single simultaneous process. The prerequisites for this are that the liquids are not soluble in each other, that they have different densities and that the solids phase has the highest specific weight. On this basis, the specially designed impeller system produces optimum separation results.

Three-phase separation offers users several advantages: The combination of the processing steps eliminates the need for additional separation stages, which results in considerable cost savings. In addition to its high selectivity, the Tricanter^® is particularly attractive because of its versatility. It can adapt to changing inlet conditions at any time. In addition, there are the proven engineering and Flottweg services, from application-oriented project planning, through commissioning, to maintenance and spare parts supply. Thus, users benefit in the long term from the highest quality "Made in Germany."

How the Flottweg Tricanter® works

The design and function of the Flottweg 3-phase centrifuge is similar to that of a decanter (two-phase separation). Solids settle on the inner wall of the bowl when subjected to centrifugal force. The scroll constitutes the conveying tool. Under centrifugal force, solids settle on the inner wall of the bowl.

The decisive difference to the decanter lies in the separate expulsion of the two liquid phases: With the Tricanter^®, the heavy liquid is discharged under pressure via an adjustable impeller. The light liquid flows off without pressure. The impeller allows infinite adjustment of the pond depth during operation and thus fast, precise adaptation to changing feed conditions - without interrupting operation.
