ABSTRACT:
Methods and apparatus for concentrating liquid-containing substances are disclosed. The disclosed method includes contacting liquid-containing substances such as fiber suspensions with separating means as the substance flows in a first direction so that a portion of the liquid is separated from the liquid-containing substance, withdrawing the liquid through the separating means in a second direction, intermittently interrupting the flow of the liquid downstream from that point of withdrawal to terminate the flow of the liquid through the separating means and preventing return flow of the separated liquid through the separating means. The apparatus disclosed includes means for directing the flow of the liquid-containing substance in a first direction, separating means for separating a portion of the liquid therefrom in a second direction, means for interrupting the flow of the separated liquid downstream from the separating means in a second direction, and means for preventing the return flow of the liquid through the separating means. In a preferred embodiment the apparatus includes a membrane which acts as a non-return valve for the separated liquid during interrupted flow of the separated liquid.
