  • Patent number: 6602416
    Abstract: A method and a device for purifying waste water is described, in particular for an anaerobic purification, in a container receiving a medium under the development of gas, wherein the gas developing is caught by a gas collector, ingredients of the medium entrained by the gas are separated and the ingredients separated are passed back into the medium below the gas collector. In order to improve the purification effect in a constructively simple manner, it is suggested to take in medium from the upper portion of the container by a gas lifting effect of the rising gas and to conduct it back into the container.

  • Patent number: 6478963
    Abstract: Described is a method and a device for purifying waste water, in particular by means of anaerobic purification. The method is carried out in a waste water- and sludge-receiving container under generation of gas, the developing gas being trapped by a gas collector and the circulation formed by the ascending gas being used for loosening the sludge which has settled on the bottom of the container. Such a method is to be developed in a constructionally simple and more efficient way. To this end the settled sludge should be sucked from the bottom by a gas lifting effect provided by the ascending gas, and should be passed into the upper portion of the container in a condition separated from the waster water in the container, and returned into the waste water.

  • Patent number: 6278518
    Abstract: A process for characterizing at least one sample comprising at least one substance (Si), in which at least one substance (Si) in the sample is identified and in which at least one quantity (Gji) which characterizes a substance (Si) in the sample is determined, at least the following process steps being carried out successively or simultaneously in an analytical centrifuging device: a) centrifuging the sample in an analytical centrifuge, b) exposing the sample to monochromatic light, preferably laser light, c) detecting light scattered by the sample, d) identifying at least one substance (Si) by a spectral evaluation of the inelastically scattered fraction of the scattered light which was detected in step c), e.g. by means of Raman scattering, and e) determining at least one quantity (Gji) for a substance (Si) by evaluating the state of the sample which it has entered as a consequence of the centrifuging in step a).
