Problems solved by technology

[0004] However, if the screen elements become fouled, the efficiency of the system is reduced. In addition, the screen elements are subjected to heavy loads, especially when the pressure differential between the feed and the pond or the drain of the pond increases due to fouling Time

Embodiment Construction

[0048] The filter system 1 comprises a filter unit 2, which is further referred to below Figure 2-4 described in more detail. The filter system 1 also includes a tank 4 to contain the liquid filtered by the filter unit 2 . The pool 4 at least partially surrounds the filter unit 2 .

[0049] exist figure 1 The level of the liquid in the tank 4 or filter unit 2 or feed tank is shown schematically in ▼ express). The maximum liquid level is preferably such that the filter unit 2 is not completely submerged in the liquid. Therefore, it is sufficient that the pool 4 surrounds the filter unit 2 to the extent that a desired liquid level can be achieved in the pool 4 or in the filter unit 2 . The pool 4 may for example be formed by a water tank (not shown here) with suitable side walls. However, the pool 4 can also be part of a channel or a pool of a plant such as a purification plant.

[0050] The filtration system 1 may also comprise one or more covers 6 which cover the pool ...

Abstract

A filter unit (2) for filtering a liquid includes a bracket (10) rotatably supported about a rotational axis (12) and including a plurality of bracket portions (14) disposed about a circumference thereof. In each bracket portion (14), two first screen elements (16) are arranged to extend outwardly from the circumference of the bracket (10) and approach each other with an increase in the distance from the circumference of the bracket (10) in the radial direction with respect to the rotational axis (12). Furthermore, in each bracket portion (14), a second screen element (18) is provided, which extends substantially along the circumference of the bracket (10) such that the two first screen elements (16) and the second screen element (18) of the bracket portion (14) are arranged substantiallyin the form of a triangle. The mesh size of the second screen element (18) is greater than the mesh size of the first screen element (16).

Description

technical field [0001] The invention relates to a filter unit for filtering liquids and to a filter system comprising such a filter unit. Background technique [0002] A filter unit or filtration system removes solids, particles and suspended solids from the liquid to be filtered. They are used, for example, in purification plants (especially as a third and often last purification stage), drinking water installations and in industrial applications, for example for recovering materials from liquids or for filtering cooling water. Filter units or filtration systems can also be used to remove algae from water or to treat drinking water. [0003] For example, a filter system is known from EP 3 391 949 A1 with a filter unit arranged in a tank and comprising a frame on the circumference of which a plurality of screen elements are arranged. The bracket is rotatably supported around a feed pipe which supplies raw water to be purified. Raw water to be purified is supplied to the f...
