Patent number: 6602416Abstract: 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.Type: GrantFiled: April 30, 2002Date of Patent: August 5, 2003Assignee: USF Deutschland GmbHInventor: Peter Rossmanith

Patent number: 6478963Abstract: 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.Type: GrantFiled: December 27, 2000Date of Patent: November 12, 2002Assignee: USF Deuthschland GmbH GutlingInventor: Peter Rossmanith
