Method and device for eliminating foreign matters present in dissolved form from waste water

The invention relates to a device and a method for continuously eliminating foreign matter present in dissolved form from waste water, comprising the following steps: a) through-flow of a reactor (1) with waste water in a flow direction (2), b) adding of magnetic or magnetizeable particles to a feeding point in the reactor (1) to the waste water, wherein at least one foreign matter is attached to the particles, c) separating of particles charged with foreign matter to another spot in the reactor (1), located opposite the feeding point in the downward flow direction by applying a magnetic field to the waste water flow for the transport of particles into a collecting area (3a, 3b) connected fluidic with the reactor (1)and d) separating of the particles and the foreign matter connected to the particles from each other. The invention relates to a device, suitable for the process of said method, comprising a reactor (1) for receiving of waste water polluted with pollutants, having a collecting area (3a, 3b) for po
