The disclosure refers to a method, reaction chamber and system for treatment of liquids in continuous flow including the steps of receiving a liquid for treatment in a reaction chamber; converting q flow of liquid for treatment in a biphasic liquid-gas flow; directing the biphasic flow to a central section of the reaction chamber, where an electric field is applied; ionizing the gaseous fraction of the biphasic flow that passes through said central section sustaining an ionization regime generating non-thermal plasma throughout the central section of the reaction chamber leading the biphasic flow under the ionization regime to a discharge section of the reaction chamber, where the electric field is applied, generating the deionization of the gaseous fraction and causing the biphasic flow to reduce its velocity, which results in the condensation of biphasic flow; and removing a flow of treated liquid from said discharge section.

The method according to claim 1, characterized in that the flow of fluid speeded up under turbulent conditions generates a pressure drop in the inlet section of the reaction chamber, promoting that the biphasic flow has a great contact surface between the phases forming it.
The method according to claim 1, characterized in that the step of converting the flow of liquid in the biphasic flow is promoted by the partial release of gases dissolved in the fluid to be treated and the partial evaporation thereof.
The method according to claim 1, characterized in that the central section comprises at least a pair of electrodes that generate the electric discharge to produce the electric field applied in said central section.
The method according to claim 4, characterized in that the step of obtaining the discharge of plasma in the biphasic flow comprises the application of an electric field between the electrodes, which intensity exceeds the breakdown voltage of the gaseous phase of said biphasic flow.
The method according to claim 5, characterized in that the electric field is generated through a potential difference between the electrodes, where said potential difference is applied by at least one high-frequency power source.
The method according to claim 6, characterized in that the step of sustaining the ionization regime generating non-thermal plasma comprises the use of a current limiter in order to limit the current circulating through the electrodes.
The method according to claim 7, characterized in that the current limiter is integrated in the at least one power source that applies the potential difference.
The method according to claim 1, characterized in that leading the biphasic flow under the state of plasma to the discharge section of the reaction chamber comprises reconverting the biphasic flow in a flow of liquid.

A reaction chamber for the treatment of liquids, characterized in that it comprises:
The reaction chamber according to claim 11, characterized in that the nozzle comprises a discharge section expanding into the reaction chamber by increasing the cross-section of said discharge section of the nozzle, generating a pressure drop in the inlet section of the reaction chamber.
The reaction chamber according to any of claim 11, characterized in that the nozzle speeds up the flow of fluid in order to reach a speed between 15 and 60 m/s.
