DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

[0036] FIG. 1 shows a primary reactor 1 for a first cleaning of the wastewater, for example from solid content substances, such as suspended solids. An initial treatment can be carried out by the electrodes 22, as a result of which the solid contents can be agglomerated and thereby removed. The wastewater to be cleaned is introduced into the primary reactor through the inlet 3 and discharged from the primary reactor through the outlet 4. The primary reactor 1 has an outlet 23 for ventilation, whereby harmful or explosive gases can escape from the system.

[0037] FIG. 2 shows a secondary reactor 2 in a side view. The secondary reactor 2 has in its direction of flow, direction in which the wastewater flows, starting from the inlet towards the outlet a cascading of metal plates 5 and 6, to which an alternating electromagnetic field is connected. A separating device 7 is arranged shortly before the outlet, which separates the differently charged water, i.e., the split up molecules.

[0038] FIG. 3 shows the secondary reactor viewed from above with the metal plates 5 and 6. The metal plates 5 are cathodes in one half-wave of the voltage supply, i.e., negatively charged, and the metal plates 6 are anodes, i.e., positively charged. In the following half-wave, the charge changes. Near the inlet 3 several metal plates 5 and 6 can be arranged one behind the other perpendicular or transverse to the direction of flow. The charges can be formed in an alternating manner perpendicular to the direction of flow, so that an anode metal plate alternates with a cathode metal plate. Further metal plate packs 15, 17 and 18 can be arranged along the direction of flow, whereby the arrangement can increasingly be such that on one side more anode metal plates 6 and on the other side more cathode metal plates 5 are arranged. In a last package 15, on one side only anode metal plates 6 can be arranged and on the other side only cathode metal plates 5 can be arranged. The wastewater and/or its content substances are then separated in such a way that on one side the positively charged content substances and on the other side the negatively charged content substances are gathered. In the further direction of flow 10 a separating device 7 having a separating wall 8 can be arranged in such a way, that the differently charged parts are separated and can be collected in different outlets 4.

[0039] FIG. 3 shows in particular a pack of charge carrier plates 17, wherein the respective individual plates 5 and 6 can have a different charge. Said charge plate pack 17 is arranged in a first section of the device close to the inlet, wherein the individual charge plates 5 and 6 are arranged alternately in the direction up or down, respectively, with respect to the plane of the drawing. In this front section of the device, it is exclusively about adding energy to the wastewater, wherein the energy should have a frequency that corresponds to the resonance frequency of the molecule or atom to be split up or should at least be in its proximity. A separation of already split up content substances is not possible in this section, since a splitting up has not yet occurred. In addition, the alternating arrangement is also advantageous because a merely short distance can be realized between differently charged plates 5 and 6 as a result. This makes it easier to build up a strong voltage field. At the end of the device another charge carrier package 15 with individual plates 5 and 6 is arranged. In this charge carrier package 15, the plates 5 and 6 are arranged in sorted manner according to their charge. In the drawing, the plates 6 are arranged at the top and the plates 5 at the bottom. In this section at the end of the device, the content substances have already been split up during their run through the device, which is why only a separation and filtering of the split up content substances is carried out in this section.

[0040] The charge packs 18 guide the differently charged split up parts of the content substances into different containers.

[0041] A flocculation of ingredients is therefore prevented by electromagnetic fields or waves, with an excitation of the molecules of the ingredients being intended. For this purpose, the metal plates in the secondary reactor 2 are provided, which supply energy to the content substances to be precipitated in resonant compatibility. This results in an inharmonic overshoot, which causes charge separation within the atom and/or molecule of the content substance and ultimately the breaking apart of the atom or molecule into its differently charged parts.

[0042] FIG. 4 shows a cover of a secondary reactor having a suction opening 19 for existing or emerging gas components.

[0043] FIG. 5 shows the secondary reactor 2 in a side view with the inlet 3 and the outlets 4, 20 and 21.

[0044] The outlet 4 serves for the discharge of floating layers. The outlet 20 is provided for the discharge of the clear phase and the outlet 21 is provided for the discharge of the bottom sludge. The webs 14 serve for fastening, for support or for arrangement of the electrodes 5.

[0045] FIG. 6 shows the secondary reactor 2 with the suction opening 19, so that gases produced, for example noxious, combustible or explosive gases, can escape from the secondary reactor 2 and/or be suctioned off. The secondary reactor 2 is shown in a top view, with the cover 24 resting on the secondary reactor 2.

[0046] FIG. 7 shows in a top view the secondary reactor 2 with the inlet 3 and the outlets or drains 4, 20 and 21. The secondary reactor 2 is shown in a top view without the cover 24.

[0047] FIG. 8 shows the complete system with the primary reactor 1 and the secondary reactor 2 in a top view.

[0048] Collecting containers 16 are also shown.

[0049] FIG. 9 shows the complete system with the primary reactor 1 and the secondary reactor 2 in a side view.

[0050] In addition, collecting containers 11, 12 and 13 are shown.
