ABSTRACT:
A separation means for a liquid medium containing undissolved constituents comprises a chamber (10) with dynamic membrane (11, 12) arranged therein, said membrane consisting of a porous support matrix (11a, 12a) or other support matrix with through holes, and a layer (11b, 12b) of a small-sized particle material generated thereon in the chamber. In such a separation means the flow of the liquid medium is split into two streams, one constituting the permeate stream which penetrates through the membrane and the other constituting the reject stream which flows past the membrane. To regenerate the membrane, the deposit of said undissolved constituents formed on the membrane during use of the separation means is removed from the support matrix, with the aid of one or more movable devices (21b, 22, 23) brought into mechanical contact with the layer of particle material and moved along the support matrix by a rotor (21) arranged in the chamber, while at least a portion of the particle material is allowed to remain on the support matrix.
