  • Patent number: 7527817
    Abstract: The invention relates to a method for reducing the total bacteria count in aqueous dispersions by means of sterile filtration of said dispersions using deep-bed filters (18, 22) pertaining to at least one deep-bed filter device, under pre-determined conditions, notably the temperature of the non-filtered part, the differential pressure in the deep-bed filters (18, 22) and the flow speed of the non-filtered part in the respective deep bed filter device.
    Type: Grant

  • Patent number: 6951614
    Abstract: A method for filtering liquids, especially drinks, is by a filtering device having at least two filter lines. Each filter line has at least one filter unit with at least one preliminary filter and one terminal filter which can be connected to or disconnected from the respective filter line independently of each other and which can also be independently regenerated. The pressure differential of at least one filter unit on each filter line is measured. Once a predefinable threshold value is reached for the pressure differential, the volume flow entering the device is reduced. The associated filter unit is disconnected from the filter line. The reduced volume flow to be filtered is handled by the corresponding filter unit in the other filter line which is fluidically connected to the filter line between the respective preliminary filter and the respective terminal filter. The disconnected filter unit is regenerated.
