  • Patent number: 11136248
    Abstract: A purification device for purifying a liquid comprising a container (1) having an inlet (8) for the liquid and an outlet (9) for the liquid and a filter (10) arranged in the container (1), said filter (10) comprising activated carbon and precious metal particle and/or semi-precious metal particles and/or valve metal particles distributed in the activated carbon. The filter (10) is placed in a flow path of the liquid, the flow path of the liquid being chosen so that the liquid enters the container (1) via the inlet (8), enters the filter (10) via a lateral surface (15) and flows radially inwards towards an inside of the filter (10) and then out via 9? the outlet (9).
