Abstract
1. Method to separate liquids from heterogeneous mixtures, containing liquids and solid particles, in order to drain or concentrate community or industrial sludges, especially low viscosity sludges whereat sludge will be pumped to a container at a lower pressure and thereafter at a comparatively higher pressure and a filtrate will be drawn off from the volume of the container, submitted to pressure, or the sludge cake, respectively, within the container, characterized in that in the method a transportable container is applied, which is provided with a filter mesh or a fine mesh sieve whereat the action upon the sludge is supported by the gravity force and the method will be applied in fractional portions of a pressure-time diagram of the container, comprising the sludge and having a hydraulically directly and continously connected pressure volume, in which diagram increasing pressure values will be applied which are linear and/or of square tape and whereat increasing structure of pressure and the pressure distribution in the filtrate sludge will be carried out intermittently and/or in a pulse type.
