The invention relates to a disc filter sector and a disc filter.
The disc filter (1 ) comprises several triangular sectors (5) that are connected from their neck section (12) to the body (4) of the disc filter.
A rotary disc filter is provided with a system for inhibiting biological fouling from biological growth on filters that form a part of the rotary disc filter.
A backwash shoe (24) for a rotary disc filter (21) is disclosed.
The disc filter includes at least one disc (2) and oscillating showers that periodically remove a precoat layer of solids from the surface of the disc.
The colour changer may be a rotatable colour wheel filter, an endless band filter or a cylindrical filter.
The disc (44) cleans the well as it is retracted.
A rotary disk filter comprises a rotatable drum (2) and at least one disk-shaped filter member (10), which on the outside of the drum extends outwards in the transverse direction of the drum.
The disk filter includes, in a flow passage for liquid, a stacked body composed of the filter disks (21).
The disc (44) drops clear of the tube (18) allowing the disc (44) to be cleaned before re-insertion.
The disk filter can appropriately and efficiently filter even a low-pressure liquid.
When the cover is removed, the tube (18) and the disc (44) are removable as a pair.
A version for spa baths has a screw operated disc for making the outlet function as a plug.
As a result of this configuration, the pressure loss of the disk filter is low and the opening ratio thereof is high.
