Definitions
- Comprise proportion of aqueous solution there is the problem of adding the pore channels, which are preferably in the range of 3 - 5000 nm nominal pore size. Larger particles or agglomerates contained in the solution are deposited on the membrane surface without binding to it, reduce the free surface and thus set the pores of the membrane
- the object of the invention is therefore to provide a process for the pretreatment of liquids, in particular those containing at least a portion of water
- the crystallites formed in this way can also be deposited on the pore channels, but do not form any firmly bonded to the pore material
- the magnetic fields can be generated, for example, by permanent magnets or in an alternative embodiment by electromagnets.
- Fig. 2 a greatly enlarged view of a membrane filter with the
- Tangential flow filtration is characterized by the presence of two volume flows, the speed v 1 of the filtrate perpendicular to the membrane surface 1, the so-called permeate esc speed, and the speed v 2 tangential to the membrane surface 1, the so-called overflow speed.
- Volume flow Q 1 determines the filter or permeate performance and volume flow Q 2 the overflow volume, which is to largely prevent the deposition of substances on the membrane surface 1 by tangential rinsing.
- Permanent magnetic designs are also conceivable, as is known, for example, from "WWF Panda 2000 Catalog of Spring & Summer 1998, p.242".
- work should preferably be carried out at a high overflow rate of the liquid medium.
- an alternating field is preferred.
- the precipitation of crystals 28 is induced by the applied magnetic field.
- the liquid to be filtered can be pretreated in one or more facilities. This happens for example in the
- Pretreatment system 101 which in the case shown comprises a total of three pretreatment devices 108, 110 and 112, a precipitation in the first pretreatment device 108, a flocculation in the second pretreatment device 110, and the third pretreatment device 112 a sand filter.
- the device according to the invention for generating magnetic, electrical or electromagnetic fields can be arranged in a wide variety of locations in the membrane filter system shown, for example an arrangement in front of each of the individual pretreatment devices or between them would be possible, as indicated by the reference numbers 122, 124, 126 and 128.
- Pretreatment system 101 would also be possible to arrange in the area of treatment device 100 itself.
- the device according to the invention could be arranged between pumps 106 and 104, directly in front of the membrane filter device 102 or in the area of the membrane filter device itself and in the return line 129 of the membrane filter device 102
