| 摘要 |
The invention relates to a membrane filter unit for filtration of a suspension, comprising at least one container (41), for the suspension to be filtered, a device for introducing gas (7) into the suspension, a membrane filter module (11), passed in the direction of flow, arranged downstream of the gas introduction device (7), a device for draining the permeate (30), obtained by the filtration and a device, preferably a circulating pump (42), which pumps the suspension to be filtered through the membrane filter unit. The gas introduction device (7) is in the form of a throughflow, non-blocking tube gasification unit. Furthermore, the suspension (40) is gassed in such a way that the pressure difference DELTA <i>p</i> between the inlet and outlet of the membrane filter module (11), after taking into account the hydrostatic pressure of the fluid column of the suspension (40) in the membrane filter module (11), is zero. An optimal filtration capacity and a high efficiency for the filter unit can thus be guaranteed. |
