Chemistry, Pharmaceutical and Biotechnology Food industry Environmental, recycling and specific applications SOLID/LIQUID SEPARATION Solid/liquid separation: separation of mixed suspension of solid phase in liquid. It consists of two distinct methods: • Filtration (or spinning) • Decantation LIQUID/LIQUID EXTRACTION Commonly known as solvent extraction, it consists of transfer of a substance contained in the dissolved state (or solute) in a liquid phase to another liquid phase immiscible with the first one and of a different density, thanks to the difference in affinity of this solute in relation...

SOLID/LIQUID SEPARATION The solid/liquid separation by centrifugation can be achieved by two different technologies: centrifugal filtration (or spinning) and centrifugal decantation. Centrifugal filtration Centrifugal decantation: Separation of solid and liquid phases of one solution is achieved by the liquid flowing through the filtration media under the pressure generated by centrifugal force. Filtration media, perforated basket wall, with eventual filtration cloth covering it, allows solids retention inside the rotating basket. The centrifugal decantation (or sedimentation) is performed thanks...

LIQUID / LIQUID EXTRACTION Liquid / liquid extraction or solvent extraction, consists in transferring one (or more) solute(s) contained in a feed solution to another immiscible liquid (solvent). The solvent that is enriched in solute(s) is then called extract and the feed solution that is depleted in solute(s) is called raffinate. The general principle consists first of mixing the initial liquid solution containing the solute with solvent which has been chosen for its affinity with the solute. After that, the created dispersion is decanted statically (by gravity) in mixer-settlers or dynamically...

CENTRIFUGAL PARTITION CHROMATOGRAPHY Operating principle of the centrifugal partition chromatography is very simple. A system composed of 2 liquids constitutes the core: • One of the phases is chosen to be stationary. This phase is maintained stationary by centrifugal field. • The other phase is mobile. This phase, by means of a pumping system, goes through the column created by the centrifugation. The solutes of interest are injected on the top of column and will migrate along it. They are carried by the mobile phase and will be distributed along the column between two liquids, according to...
