FIWLD: filtering.

SUBSTANCE: invention refers to the method of I and II carbonation juice filtering, syrup filtering in sugar refining industry. The filter cartridge contains a vertically installed body formed by two perforated plates having central parts that form together an ellipse in the cross-section area and peripheral parts radially located against cartridge vertical axis, a filter cake discharge tube installed inside the body throughout its height and filtering cloth fastened on the outside of the body. Radial peripheral parts of the plates form converging channels. Each perforated plate is inward bent in the area between the central and peripheral parts. The filtering cloth is fixed on the cartridge surface being movable against outside surface of the said parts for its clearing from cake. The surface of the filter cartridge radial peripheral parts should be made wave-like.
