Abstract

A method and a device for a liquid filtration, polluted liquid being fed into a filtration device (1) above a filter (28) and a portion of the filtrate, obtained in this way, being reversed for a counter flushing and thereby a cleaning of the filter. The object of the invention is to run the process continuously, and this object is achieved according to the invention by dividing the device into a number of cells (11-14), each one of which contains its filter and which cells are mounted around a main chamber (9) for the filtrate. The cells communicate with the main chamber via their respective intermediate chambers (20-23) and openings (24-27) located in the common partition wall. The opening of the cell, which is to be subjected to a counter flushing, is connected, by means of a driving unit (46), to a reversed liquid flow, and simultaneously the inlet opening (34-37) for polluted liquid to this cell is blocked and a connection to a flushing liquid outlet established. While the counter flushing of one cell is in progress, the rest of the cells continue to filtrate polluted liquid.
