Problems solved by technology

The disadvantage in this case is that the clarified liquid required to clean the filter returns to the container due to the accumulation of solids and is filtered again, which reduces the filtration efficiency
The filter unit requires high rotational speeds when connected to the drive, which can lead to premature wear of the material
Manufacturing costs and energy consumption are relatively high

Embodiment Construction

[0024] Figures 1 to 3 A first preferred embodiment of the invention is shown: the filter device 1 is arranged rotatably in a liquid-filled container 2 . It has multiple filter modules 3 . The individual filter modules 3 are combined to form a plate-shaped filter element 6 with, for example, a circular or polygonal perimeter. The individual filter elements 6 are connected at a spacing of, for example, 4 to 8 mm. The filter module 3 making up the filter element 6 is formed, for example, from a plurality of substantially parallel filter plates (not shown), as is known per se. The filtrate is led off through a filter plate with filters on both sides. The distance between the filter elements 6 can be adjusted by means of the spacer discs 7 . A ventilation device 8 is fixed horizontally in the cavity 4 . The ventilation device 8 consists of hollow bodies 10 arranged parallel to a hollow shaft 9, which extend over the entire width in which the filter element 6 is present, and a...

Abstract

The invention relates to a filter device for separating undissolved substances from liquids, especially in the fields of waste water purification and water treatment. Said filter device is rotatably arranged in a container (2) and surrounded by the liquid to be filtered. The inventive filter device (1) consists of a plurality of interspaced filter elements (6) which are assembled to form a rotating filter. The filtrate is drawn off at the periphery of the filter elements (6). The aim of the invention is to prevent solids from adhering to the filters during the filter process. To this end, the rotating filter has a central cavity containing a ventilation device (8) about which the filter device rotates. The filters are continuously cleaned during the filter process by the air-liquid mixture flowing through.

Description

technical field [0001] The present invention relates to a filter device for separating undissolved substances from liquids, especially in waste water purification and water treatment. In particular, such filter devices are used in biological wastewater treatment to separate active sludge from treated wastewater. Background technique [0002] Known filter devices have filter elements at a distance from one another, which are combined to form filter modules and are arranged rotatably in a circular or polygonal configuration in a container containing the filter liquid. Filter plates with filters on both sides, or porous hollow fibers, are used as filter elements. The filtrate is drawn through piping around the filter element. As the filtration time increases, solids retained from the filtered liquid accumulate on the filter surface and thus impair the filtration process so that the efficiency of the filter device deteriorates. [0003] From DE 195 37 578 it is known to provi...
