The invention relates to a mobile water treatment plant for producing potable water in a disaster area, comprising a first filter unit (14, 16), which has a filter element (50) for filtering the raw water, a first and a separate second raw-water connection (52, 54) on a raw-water side of the filter element (50), and a first filter connection (56) on a filtrate side of the filter element. A raw-water inlet (92) is used to supply raw water. A filter pump (18) is arranged between the raw-water inlet (92) and the filter element (50). The filtrate connection (56) is connected to a potable-water outlet (73). A control unit activates the filter pump (18) during filtration operation in order to press the raw water through the filter element (50). Furthermore, the plant has an adjustable three-way control element (34), which has a first, a second, and a third valve connection (58, 60, 62), and a separate raw-water outlet (68). The first valve connection (58) is connected to the first raw-water connection (54) of the filter unit (14, 16). The second valve connection (60) is connected to the raw-water outlet (68). The third valve connection (62) is connected to a first raw-water line (46), which leads from the filter pump (18) to the second raw-water connection (54) of the filter unit (14, 16). The new water treatment plant enables thorough cleaning of the filter element (50) in an easy manner and easy and compact implementation. |
