- Chemical cleaning processes are essentially based on circulating chemical solutions through the reactor that break down and remove dirt and, less successfully, deposits that may form on the electrodes as a result of passivation; and the mechanical cleaning processes are essentially based on rubbing or scratching the electrodes to remove from their surface that outer layer of dirt and, more successfully, deposits resulting from passivation that may have formed on them.
- the abrasive particles operate without interrupting the operation of the reactor.
- the nature of the particles is non-conductive.
- An objective of the present invention is an alternative solution to those known.
- Materials that alter the electric field or the conditions inside the reactor during its operation must be discarded. In practice, this means having to discard conductive materials, although these could have better mechanical properties and give rise to harder and more efficient particles.
- known solutions involve contaminating the water being treated.
- the abrasive particles wear down and are able to escape from their confinement. In practice this can lead to the presence of microparticles in the reactor effluent.

- annular space is determined for the transit of the liquid to be purified 3, when the reactor 1 works in operating mode; but also for the transit of a cleaning medium 5, when the system 100 operates in a cleaning mode.
- the system 100 is an intelligent system, with means to monitor those physical parameters from which it can be inferred that the conditions inside the reactor 1 when it works in operational mode and without changing the typology of the liquid to be purified have deviated from an optimal pattern that defines certain ideal conditions.
- the expert knows the intensity of current per hour / liter that must be applied by the power supply to achieve a desired level of purification and that gives rise to a voltage curve over time (due to that the distance between electrodes is a function of the hours of operation, said distance varying according to the wear of the electrodes, especially the anode).
- the conductivity and temperature of the liquid effluent to be purified 3 are controlled and the information obtained is sent to a controller that also receives information related to the voltage of the power supply. With these three readings, it is automatically determined whether, depending on the two variables of conductivity and temperature of the effluent, the measured instantaneous voltage fits the voltage curve. If the difference between the instantaneous voltage and the voltage curve is greater than a predetermined value, the controller can automatically generate a signal to activate the system 100 in cleaning mode.

- a fraction of purified liquid 3b can be driven by means of impulse 10 back towards the reactor 1, previously mixed with new liquid to be purified 3a so that the balance of flow in circuit 6 remains stable. In this way, it also contributes to having a minimum flow and velocities of the liquid to be purified 3 introduced into the reactor 1 when the availability of new liquid to be purified 3a is not sufficient for this.
- Drive means 10 may comprise a conventional liquid pump.

Likewise, it also includes mechanisms with two single inlet and outlet outlets as well as mechanisms with more than one inlet and/or outlet outlet; switchable, operable manually or automatically.
- the cleaning liquid can be formulated comprising components or products with cleaning properties, so that the mechanical cleaning phase of the mentioned cleaning cycle is actually also chemical cleaning.

- the cleaning medium 5 mixture of cleaning liquid and abrasive particles is recirculated several times through the reactor 1, but at its outlet this cleaning medium 5 is separated into a stream rich in particles and a stream of used liquid without particles, both streams being conducted by different lines of circuit 6 and driven by different means to meet again before entering the reactor 1 to produce a new mixture of cleaning liquid and abrasive particles, not necessarily in the same proportion and also being able to have cleaned the particles if they are reused and/or being able to add new particles to the mixture that gives rise to the cleaning medium 5 to be introduced into the reactor.
- the recovery branch 61 also has a collector 8 of recovered particles 52a that connects with the outlet of the separating means 7; and at least one means of adding particles 9 to a liquid cleaning stream free of particles to form the cleaning medium 5 that enters the reactor 1, adding means 9 that are supplied with recovered particles 52a of the cleaning medium 5 accumulated or collected in collector 8.
- the separating means 7 comprise, in the example, a cyclone separator.
- the cyclone separator can be, for example, made of stainless steel or polyurethane. Other types of separators can be used depending on the type of abrasive particle to be used, alternatives to the cyclone separator may be separators by filtration or decantation.

- the control of the extraction valve means 14a and/or the associated bypass valve means 63a will allow the fraction of effluent, purified liquid, to be recirculated back to reactor 1 to be established.
- the addition means 9 will be stopped and the appropriate measures will be taken so that particles contained in collector 8 are not added to the liquid to be purified 3 that is led to reactor 1.
- the valve means 61a will be open and the bypass valve means 63a associated with the by-pass branch 63 closed.
- the addition means 9 will be in operation for the addition of recovered particles 52a to the cleaning liquid, preferably formed entirely by used cleaning liquid 51a that is recirculated to the reactor 1, and obtain the cleaning medium 5 that is led to the reactor 1.
- the abrasive particles contained in the cleaning medium 5 strike and rub against the electrodes as they pass through the reactor 1, cleaning and/or regenerating them.
- the cleaning liquid circuit 6 can be emptied, preferably through the emptying connection 13.

- the valve means of the system are governed so that the rinsing liquid can circulate through the branches or sections that it is of interest to rinse.
- the recovery of the particles outside the reactor in the collector 8 allows their chemical cleaning externally and without these chemicals having to circulate through the circuit 6. This makes it possible to reduce the consumption of reagents and protect to the electrodes of these, in comparison with the solutions in which the particles are confined inside the reactor, being necessary the chemical cleaning of the particles inside the reactor.
- the collector 8 is further equipped with stirring means 81 operable in coordination with rinsing means 82 forcing the circulation of a rinsing liquid in an upward direction through the stirred mass of recovered particles 52a contained in the collector 8.
- the rinse liquid can be water with or without chemicals.
- the rinsing means 82 may be a separate circuit from the one hydraulically connected to the reactor so that the rinsing liquid used to clean the recovered particles 52a does not reach the reactor.
- the agitation means 81 may act within the manifold 8 or the manifold 8 itself may be agitated. In any case, the agitation of the mass of recovered particles 52a helps to eliminate the dirt adhered to them and that will be carried by the rinsing liquid out of the system.
- the system 100 of Fig. 1 is designed so that a cleaning cycle can have other phases in addition to the mechanical cleaning phase.
- a phase solely for chemical cleaning of the reactor 1 before or after the mechanical cleaning phase, using a cleaning medium without particle load such as such as water-based with dissolved HCI or other known cleaning products.
- the invention is exemplified, specifically a mechanical cleaning phase of a cleaning cycle, in i) four different reactors: with one treatment unit, with five treatment units, nineteen units treatment and sixty-one treatment units, respectively, each treatment unit of the type illustrated in Fig. 2; ii) according to various scenarios: initial and 50% attrition; and iii) starting from the same initial conditions: corresponding to new anodes with a diameter of 50 mm, the internal diameter of the cathode being 56 mm, in each treatment unit. All of this is summarized in the following Table 1.
- Table 1 Reactor parameters and flow conditions in system cleaning mode.
- the speed of circulation of the medium through the treatment units will be at least 0.5 m/s, therefore, and starting from a speed of 1 m/s in initial conditions, the flow will increase by approximately 50% when the wear scenario of Table 1 is reached.
