  • Publication number: 20020185439
    Abstract: A process is provided for the removal of organic substances (TOC), pesticides or other specific compounds from an aqueous salt solution, for example from a regenerate derived from water purification. The TOC-containing aqueous salt solution is treated in a desalination membrane according to the dead-end principle, wherein neither longitudinal flow over the membrane with air and/or water, nor continuous concentrate discharge takes place, after which the obtained permeate is reused, and the concentrate obtained after flushing is discharged. The TOC-containing aqueous salt solution is introduced at the feed side of the membrane module at a flux of 5-75 1/m2·h, a feed pressure of 4-12 bars for 30-40 minutes, while the obtained TOC-depleted permeate is discharged. Preferably, operation takes place at a flux of 15-25 1/m2·hr, a pressure of approximately 8 bars, and the duration of treatment is approximately 30 minutes.

  • Patent number: 4630055
    Abstract: A dipole arrangement which is located in a sheath,including segments of ejectable dipoles sequentially arranged within the sheath. The dipole can be ejected from the sheath within a short time interval and, subsequent to ejection, will rapidly form a large-surfaced and homogeneous cloud. The segments of the sheath which has a polished inner surface, as viewed in the ejecting direction, evidence an envelopment with a reducing number of windings which consists of a thin metal foil, smooth on both sides thereof, and wherein the dipoles of the enveloped segments, or the only partially enveloped segments, are centripetally pretensioned. The dipoles which are prestressed in the segments act as drive springs for the metal foil which encompass the segment whereby, dependent upon the winding number of the metal foil, there is achieved a time-delayed release of the dipoles.
