Patent number: 11198624Abstract: The present invention relates to a method for treatment and/or purification of water, in particular wastewater or drinking water, preferably for the adsorptive removal of inorganically or organically-based, impurities, such as trace substances and/or micropollutants, wherein, in a counterflow filter device, e.g. a counterflow adsorption filter column, the water that is to be treated and/or that is to be purified firstly, and, secondly, an, in particular particulate, adsorption material are conducted in a counterflow direction. In particular, a procedure is followed in such a manner that the water to be treated and/or purified is passed through a bed of the adsorption material present in the counterflow filter device for the adsorptive removal of impurities and the bed is exchanged and regenerated by preferably continuous removal and supply of the adsorption material in counterflow to the water that is to be treated and/or that is to be purified.Type: GrantFiled: May 31, 2018Date of Patent: December 14, 2021Assignee: BLÜCHER GMBHInventors: Raik Schönfeld, Jan Raiser
