Abstract

A method for recuperating valuable substances and liquids from a suspension or mixture thereof, whereby a continually circulating filter strip (20) is used, the suspension or mixture is deposited on said strip and the filter strip is integrated into the fibre treatment process. The invention is particularly suitable for producing paper, whereby a device (TD) containing one such circulating filter strip is integrated into the return system. By applying this method (which is fundamentally known per se as a sludge treatment method) to fibre production, the following effect is obtained: the valuable substances accumulate in the thickened filter cake, whereby the greater part of said substances can be re-used, and the quality of the remaining water is such that it can be re-used almost entirely in the fibre production process circuit without encumbering an internal or external purification or waste-treatment facility. One particularly preferred device comprises other devices in addition to said filter strip, whereby said combination results in an extremely compact structure and provides universal adaptability to the respective processes thus performed.
