A process and appts. are claimed for separating a fluid mixture containing impurities into two or more ingredients. The novelty is that: (a) a phase separator (T1) separates that part of the mixture forming the lower phase from that forming the upper phase; (b) each separated phase is fed by separate circuits (K2, K3) to its respective filter unit (M2, M3), in which the filtrate is retained; (c) and that in a repeat passage through the circuits (K2, K3), part of that substance retained by the respective filters (M2, M3) is then fed to the phase separator (T2). The filters (M2, M3) are cross-flow filters. |
