Abstract

The present invention discloses an apparatus for filtration of liquid, wherein a granular filter medium forming a filter bed (FB) in a filter tank (1) moves downwards, while the liquid to be filtered is introduced into the lower part of said filter bed and flows upwards, dirty granular filter medium is taken out of the bottom of said filter bed and transported to a counter-current washer (21) by a first transport means (18) and washed with a part of filtered liquid, and washed granular filter medium is returned to the top of said filter bed by a second transport means (28). In the present invention, the first transport means, the counter-current washer and the second transport means are placed outside the filter tank. Further, in the present invention, the liquid to be filtered is introduced into the lower part of the filter bed either on its peripheral part (5) or both on its peripheral and inner parts (17).
