Abstract (en)

[origin: WO2012150390A1] The invention relates to a method, according to which: a culture medium passes through a set of consecutive so-called concentrator tanks (2); each concentrator (2) has a passive filtration unit (10) separating the inner space of the concentrator into a top space (14) and a bottom space (12); the top space (14) comprises an inlet (16), and an outlet (18) arranged at a position below the inlet (16) for extracting a more concentrated culture medium from the top space (14); the bottom space (12) comprises an outlet (32) for extracting a liquid from the bottom space (12); the inlet (16) of a downstream concentrator is connected to the outlet (18) of the top space (14) of the upstream concentrator; and a concentrated culture medium is harvested at the outlet (18) of the top space (14) of a concentrator (2). Preferably, in order to enable operation using only gravity, the inlet (16) of the top space (14) of an upstream concentrator is located higher than the inlet (16) of the top space (14) of the downstream concentrator.
