The invention relates to a device for the microfiltration, ultrafiltration, or nanofiltration and/or the emulsification of liquids. The device has at least one rotatable membrane medium, which has a filtrate/permeate side or a side facing a dispersed phase and a concentrate/retentate side or a side facing a coherent phase and which can be rotated in a container in order to produce a vacuum on an unfiltered liquid side or the side facing the coherent phase on partial regions of the at least one rotatable membrane medium in the container in small time segments at a frequency of 1-100 Hz. Said container has at least one feed for an unfiltered liquid or the coherent phase, at least one overflow for an unfiltered liquid or an emulsion, and at least one rotatable channel for filtrate/permeate drainage or feed of the dispersed phase, and a suction device, in particular in the manner of a suction strip or nozzle plate. The suction device has at least one suction strip or nozzle plate arranged parallel to the rotatable membrane medium or is such a suction strip or nozzle plate, which is attached at a distance of less than 0.1 to 10 mm from the membrane medium, and thus cleans non-permeating materials collected on the unfiltered liquid side during a filtration process from a surface of the membrane medium, or promotes drop formation of the dispersed phase exiting from a membrane surface on the side facing the coherent phase during an emulsification process. The invention further relates to uses of the device.

Filtration and emulsification device

A system for packaging a low acid liquid is provided herein. The system includes feeding unit configured to feed the low acid liquid into a filtration unit. The filtration unit is configured to filter the low acid liquid by using a number of pores provided on a micro sieve membrane. Further, the filtered low acid liquid is provided to an aseptic buffer unit configured to fill the aseptic filtered low acid liquid into packaging containers. The system further includes an automatic cleaning in place unit configured to automatically clean the feeding unit, the filtration unit and the aseptic buffer unit by decontamination using a decontaminating material.
