Abstract

The specification describes a method and a liquid-filtration apparatus (F) where in a relatively flat and broad chamber a liquid circulating in a primary circulation flows over a plane filter element (7), and a fraction of the liquid is pressed through the filter element. Arranged opposite to the filter element (7) an ultrasound transducer (T) is working at least when the filter element is cleaned by reflushing liquid from the secondary side to the primary side. During the reflushing, the distance between the filter element (7) and the transducer (T) is reduced or eliminated. The life of the filter element (7) is thereby extended.
