发明名称 DISPOSITIF DESTINE A LA SEPARATION DE SUBSTANCES TROUBLES A PARTIR DE LIQUIDES ET PROCEDE DESTINE A UNE TELLE SEPARATION
摘要 Depth filter for the separation of turbidities from liquids with permeation layers (2), in which the filter bed consists of a plurality of thin permeable membrane layers (3) which are arranged one after the other and in mutually spaced relationship perpendicularly to the principal flow direction and in which the individual membrane layers (3) contain macroholes (4) through which flows the principal proportion of the liquid throughput passing through the filter. The process for the separation of turbidities from liquids in the use of such a device makes a simple regeneration for the filter possible wherein the filter is regenerated by means of a short time cross-wise flushing of the filter bed with a superimposed upward or downward flow. In addition in the flushing phase the liquid may be exposed to an ultrasound blast.
