Beschreibung
Zusammenfassung:	An external-pressure column type hollow fibre membrane assembly able to be flushed by gas features that the dedicated glass flushing part is arranged among membran fibres at bottom, and the height/diameter ratio of column, the length/diameter ratio of membrane fibre, and the filling density of membrane assembly are reasonably set up for normalizing the moving tracing of gas and water and the flowing state of two-phase stream and making the membrane assembly work in subcritical throughput region. Its advantages are high membrane throughput and less pollution to membrane.
