The
pharmaceutical sector is vast, and applications are numerous.
Each
case should be evaluated based on the client's requirements, but we
often face the challenge of separating a broth with solvent solutions
where we want to separate the solid biomass phase with water from a
solvent.
Firstly,
it is essential that the machinery used is capable of handling
hazardous liquids.
In
various applications, horizontal decanter centrifuges with a screw
conveyor are frequently used for the separation of the majority of
the solid phase from the liquid phase, followed by vertical disc
centrifuges for the final separation of the liquid phase from the
solid phase or for separating one liquid phase from another (with
different specific weights).
It
is worth noting that tubular vertical centrifuges, which have even
greater separation force compared to disc separators, are often used
in these applications, but they have a small solid retention chamber
that can only be emptied manually.
The
typical steps to achieve a separated liquid are often: first a
decanter or tricanter, then a two-phase or three-phase separator
(sometimes this centrifuge can also be used for washing the product),
and finally a tubular centrifuge.
