A filter unit (1) for separating undissolved materials from liquids, esp. in waste water treatment plants, comprises a number of filter elements (6) in a container (2) for the raw liquid. A gassing unit (8) is used to form a gas-liquid mixture. Compressed gas is used to create a gas -liquid mixture flow to the filter elements (3). The filter elements can be rotated about a horizontal axis. |
