摘要： The invention relates to a method for filtering liquids, especially biological liquids. A filter (1) is deposited with the auxiliary filtering agent during a pre-deposition phase. In an ensuing filtration phase, the infiltrate is filtered by adding an auxiliary filtering agent. The auxiliary filtering agent forms a filter cake during the pre-deposition phase and the filtration phase. The auxiliary filtering agent is deposited during the pre-deposition phase, the proportion of regenerated auxiliary filtering agent being 30%, especially 0%. During the filtration phase, an auxiliary filtering agent is added, consisting predominantly, especially almost fully, of regenerated auxiliary filtering agent. The regenerated auxiliary filtering agent is treated with a medium over the whole pH value spectrum.

摘要： A method of filtering beverages and other liquids. To avoid the considerable ecoproblems encountered with the filter aids of known procedures, which must be thrown away, the filtering active structure of the inventive filter aids is maintained so that they may be reused as often as required. A mixture of filter aids of varying morphological and physical components is used, and constitutes a minimum of two components, namely one component of specifically heavy, chemically stable metal and/or metal oxide and/or carbon particles of fibrous and/or granular structure, and a further component, for building up the filter cake and increasing its volume, of synthetic and/or cellulose fibers having a fiber length of 1 to 5000 .mu.m and a fiber thickness of 0.5 to 100 .mu.m. To increase the filtering efficiency of the filter cake of the aforementioned components, a further component may be added that comprises fibrillated or fanned out synthetic and/or cellulose fibers, preferably having a fiber length of 500 to 5000 .mu.m and a fiber thickness of 0.5 to 20 .mu.m. The components are intensively mixed to form a homogeneous mixture, and are dosed to the liquid that is to be filtered.

摘要： With the method of processing liquids, fine to very fine organic and/or inorganic granular particles are used, whereby pursuant to the invention the particles are mixed and compressed together in a first step to form an agglomerate that is heated at least to a temperature that is near the melting point thereof. The particles are thereby fixed in place by being subjected to a process similar to sintering for a suitable length of time, whereupon the resulting agglomerate is screened, or reduced in size in a grinder, to a granular size that is suitable for an intended use. This enables stabilizing and filtering aids to be produced with predetermined or predictable physical or chemical properties that are suitable for specific processes.
