Definitions
- the present invention relates to a modular reactor for treating waste water and/or process water and a method for treating waste water and/or process water.

Therefore, the resulting filtration residue generally still contains a high proportion of water, is difficult to condition, and the remaining solids not seized by the precipitating agent must be dried out of the thin phase, for example with considerable energy input under certain circumstances.

- Inside the tubular reactor there are several electrode plates arranged as a sandwich (electrode package) around which the liquid to be treated flows completely.
- the electrode plates are electrically connected alternately to a positive or negative pole and transmit the electrically amplified vibration signals coming from the electronic control unit into the liquid to be treated.
- the strength and characteristics of the electrically amplified vibration signals are selected in such a way that they influence and thus partially change the electromagnetic interaction acting in the liquid and thus change the properties of the liquid or certain components/ingredients of the liquid.

- reactors can be connected in parallel to increase the flow rate.
- the device according to the invention and the method for this achieve a reduction in the viscosity of the starting substrate after fermentation to a fermentation residue as sediment in an aqueous environment (process water separation).
- a further advantage of the invention is that a reduction in the concentration of PO4-P in the digestate/waste water/process water by sedimentation to prevent uncontrolled MAP formation and deposits in later process steps.
- FIG. 12 shows a representation of an initial situation in which colloidal, ie organic, molecules 11 with a negative charge are present. Due to the same polarity, the molecules 11 repel each other and clumping does not take place.
- Fig. 13 shows a situation after the application of the method according to the invention, whereby a
- colloidal molecules 12 Part of the colloidal molecules 12 have an opposite polarity, whereby the Molecules 11 and 12 attract and clumping occurs.
- FIG. 16 shows a colloidal molecule 15 that has had its polarity changed by the method of the present invention. As a result, the molecules 14 and 15 can connect and segregation takes place.
- Fig. 17 shows a colloidal molecule 13 which has become electrically neutral by the method of the invention. This allows the molecules 13 and 14 to agglomerate.

- the effect of the method is set in such a way that such an effect occurs depending on the liquid present and the molecules change from a solution to a suspension.
- the organically present molecules can be more easily conditioned by polymer chains and can be more easily precipitated and thus separated by the surrounding water (H2O) as the solvent of the suspension.
- the device according to the invention consists of an electronic control unit and a reactor through which the liquid to be treated flows. Inside the reactor there are pairs of opposite electrode plates arranged along the direction of flow, similar to capacitors.
- the control unit generates electrically amplified vibration signals in the high-frequency range and transmits them to the electrode plates in the reactor.
- the Separation of the substances formed happens either directly at the reactor outlet or in downstream reaction vessels.
- the method according to the invention is characterized by the nature of the reactors and the electrode plates, the applied frequency pattern, the voltage levels, the current flow and the flow rate.
- the electrode plates inside the reactor are flushed by the waste water in a continuous process and expose the waste water to the electromagnetic pulses of the device according to the invention.
- the process according to the invention is also particularly suitable for separating phosphate and phosphonates.
- trace substances for example the human estrogens 17ß-estradiol and estrone, after treatment by sedimentation of these trace substances.
- the trace substances separated by the process can be removed from the waste water by filtration.
- the precipitated phosphorus compounds can also be separated from the treated water or waste water by suitable room or surface filtration, or other suitable separation techniques, for example by decanters.
- the process according to the invention can be used to change the viscosity, in particular to reduce it in colloidal to thin sludge suspensions, which makes it possible to significantly increase the ability to be conditioned and dewatered while at the same time reducing impurities such as phosphorus.
- the process according to the invention converts an oily suspension characterized by colloidal repulsion and very poor conditioning and dewatering properties into a water-like state which can then be easily conditioned and dewatered.
- the suspension flows through a reactor, with the
- the method according to the invention can be economically and ecologically advantageous for the organic and the inorganic components to be largely separated from the process water.
- an energetically favorable drying of the organic and inorganic components with greatly reduced volumes is achieved and a simple treatment of the remaining and largely depolluted process water is made possible in a classic clarification process, for example.
- up to 95% of the process water can be separated from the suspension and the volume to be dried can thus be reduced to up to 5% of the original volume.
- the process according to the invention reduces interfering substance concentrations, e.g. phosphate (PO4-P), in the suspension by about 90%, which greatly reduces the uncontrolled and plant-endangering formation of deposits, e.g. MAP.
- interfering substance concentrations e.g. phosphate (PO4-P)
- PO4-P phosphate
- a further advantage can be seen in the fact that a low residue concentration is achieved, which reduces the number of further process steps required or the (re)loading of an integrated purification system, for example.
- a flat reactor is used, which enables low resistance in the direction of flow and at the same time high tolerance to solids-laden or fibrous suspensions.
