Abstract (en)

[origin: FR2761277A1] The invention concerns a method for suspending solid particles (1) in a predetermined volume (2) of liquid, in a container (2) defined by a wall (3), the latter being partly insulated from the liquid by a deposit (4) adhering on its internal surface (3a), and collecting at least part of said agglomerated particles. The method is characterised in that the container is subjected to a reciprocating movement (5) along a reference direction (6), at a suitable frequency to obtain inside the predetermined liquid volume, with no other external action, an ebb and flow (7) on either side of said reference direction, removing said deposit, and dispersing the particles towards the centre of said liquid volume. The invention also concerns a device for implementing the method.
