Abstract

The invention relates to a device and method for filtering and/or purifying liquid. The device comprises: an outer housing provided with at least one outer opening; an inner housing which encloses an inner chamber, wherein the inner housing is provided with an inner opening; a purification chamber which extends between the outer housing and the inner housing, wherein the at least one outer opening debouches in the purification chamber and wherein the purification chamber is provided with a carrier material on which a biological purification film can form for filtering and/or purifying water; and wherein a side wall of the inner housing which is adjacent to the purification chamber is provided with one or more fluid throughfeed openings, and wherein, during use of the device, a substantially vortex-like fluid flow path is formed in the purification chamber, between the at least one outer opening and the fluid throughfeed openings.
