- This module stores all the programs and mathematical control algorithms, the generation of the different frequencies of the oscillators, the different duty cycles and the operating conditions of the system. The way it works is through the reception of energy from the power source (6) and the adaptive voltage programming module (2).

- This function can be performed by accessing the integrated programming switches (mini Dips) that this module consists of.
- the equipment has an element that, when activated, generates a command response specially arranged for this purpose.

- the system has the ability to perform a frequency inversion to be able to “wash” the electrodes and thus increase their useful life.
- the working algorithm by being able to send the different working modes to the electrodes, achieves on the suspended solids or dissolved solids of the liquid to be treated, a phenomenon called molecular resonance, generating that these solids modify their structure thus achieving their separation, also this This phenomenon is called dynamic electro-flocculation or dynamic electro-coagulation.

- the system may also optionally comprise devices for separating the flocs from the surface, within which there may be mentioned, pallet separators, rotary separators, overflow separators, although for this development, pallet separators will be preferred.
- the algorithm is also capable of generating new processes and work cycles in real time, according to the current and temperature measured in the conductive electrodes.
- the solid-state electronic device begins by scanning through the different modes, where within each mode, infinitesimal current pulses are produced where the ionic and covalent bonds of the dissolved solids in the sample are broken and reformed, thus generating larger flocs capable of being separated; e) formation of precipitated and / or electro-coagulated solids for their extraction from the target liquid; f) formation of bubbles pushing the electro-flocculate to the surface of the tank: g) extraction of the electro-flocculated solid to the surface of the tank, leaving the liquid clean; and h) phase inversion, only with modes 1, 2 and 3, on the electrodes to wash them, thus increasing their useful life.

- mode 40 there are 3 modes on that value 35, this is mode 40, mode 50 and mode 60.
- This configuration of modes has a relevant importance because the mathematical algorithms they can be associated and take a relative reference, differentiating the modes as "positive” or “negative” with respect to the reference value mentioned, by way of example, of 35 in the mode diagram.
- each mode can have an independent work cycle, which directly influence the power module, and this in turn, on the electrodes and finally the electrodes acting directly on the liquid to be separated, it can have different "polarities" associated with different frequencies and different duty cycles.
- the liquid or solution to be treated enters the treatment tank (14), through the inlet area of the liquid to be treated (32).
- the solid state electronic device (15) begins to carry out the first operating sequences with the pre-established modes (fig 5/9), taking the current references provided by the same conductive electrodes (12), through the programming status of the minidips (24) and their connectors (30).

This is done, once the microcontroller (1) activates the programming signal through its button (29) and the voltage regulators (26) are activated.
- the microcontroller (1) performs the measurements and analysis of operating parameters such as the different modes and work cycles, and the treatment process begins, according to the control algorithms, (whose description is set forth in the next paragraph). Once some time has elapsed (10 minutes approximately) and the level of the liquid to be treated has reached its maximum level, the generation of foam product of the same treatment (dynamic flocculation) is extracted from the treatment tank (14) by the zone foam outlet (31).
- the solid-free treated liquid (dynamic coagulation and precipitation) is extracted through the outlet zone of the treated liquid (31) of the tank.
- the precipitated solids are extracted by the solids outlet zone (34) specially arranged for this purpose.
- the separation of the electrodes is carried out through plastic bolts and spacers (35) and adjusted by plastic nuts (36), made of non-conductive material.
- This figure presents a diagram of modes applied in different samples for the separation of liquids from solids, where modes 10, 20, 30 represent the phase inversion of the frequencies used, with respect to a reference value 35.
- the modes are dimensionless values, where each mode has a dynamic frequency associated with it. If the diagram is analyzed, it can be seen that the sequence of modes "10, 20, (phase reversal) 60, 40, 50, 60, 40, 50, (in phase) 30, 10 (phase reversal)", throughout the entire diagram repeatedly, this is gives because this sequence corresponds to one of the six basic operating processes of the system.

- Figure 8/9 This figure shows a zoom of a section of the graph of figure 7/9, where mode 60 is clearly seen.
- This figure presents the integration between the mode diagram and the associated duty cycle diagram, where the relationship produced in a given duty cycle is shown, with respect to the mode used at that time. It can be noted that for the same mode there are different work cycles, which correspond to different substances present in the liquid to be treated. This means that there will be different work cycles automatically fed back as a result of the temperature and current measurements, and their analysis by the control algorithm.
- Example of treatment of liquid industrial waste (RILES) 2 This test was carried out with effluents from a company that is dedicated to preserving fruit, in 1 cubic meter (EBC) ponds, with four aluminum electrodes located at the corners of the pond. Sampling for laboratory analysis was carried out in the first third from the base of the tank on one of its lateral faces. The temperature was measured with an infrared thermometer, the total dissolved solids (TDS) were measured with a sedimentation cone (laboratory), COD (chemical oxygen demand, also in the laboratory) and the pH with an equipment to measure pH std. and the conductivity was continuously delivered by the developed system. The tests were developed by an external Eurofins GCL laboratory under national regulations DS 90, DS 46 and DS 609 for liquid waste.
