Abstract:
PCT No. PCT/CH96/00171 Sec. 371 Date Jan. 16, 1997 Sec. 102(e) Date Jan. 16, 1997 PCT Filed May 6, 1996 PCT Pub. No. WO96/36426 PCT Pub. Date Nov. 21, 1996For thickening a retentate by means of membrane filtration (ultra-/micro-filtration) to obtain the highest possible wet sludge proportion, a gaseous medium is admixed with the retentate. To this end an open feed line (13) above the retentate level (14), a porous ring (17) in the retentate, or a simple line connection (19, 20, 28, 29) in a tank (6) are proposed. A number of advantages accrue as a result of the lowering of the viscosity of the retentate achieved in this way, such as savings of energy for retentate recirculation, efficient installations because of longer series or passes of filtration modules, and savings in squeezing installations because of the direct filtration with high solid components.
