Arrangement for neutralisation or microorganisms

An arrangement for the exposure of a pumpable medium to an electric field, wherein the arrangement comprises:

• power supply for the generation of electrical voltage,
• at least one non-conducting chamber for pumping said pumpable medium, which said at least one chamber is provided with a first and a second electrode plate,
• wherein the power supply comprises at least two power supplies for the generation of an electrical voltage, wherein each power supply comprises a voltage converter (T), an electric charge storing element (C), and a switch (S1);
• a control means for controlling said at least two power supplies, wherein the control means by synchronous control of each power supply switch (S1) with a common control signal, generated by the control means in the form of a pulse with a duration of 0.1-100 microseconds, establish a serial connection between at least two of said at least two power supplies, the first electrode plate and the second electrode plate, wherein a resulting composite voltage arises between the first and the second electrode plate, which resulting composite voltage creates an electric field between the first and the second electrode plate, wherein the pumpable medium is exposed to the electric field, and
• wherein said at least one non-conducting chamber for pumping said pumpable medium is a piston pump with a piston whose top surface is one of the electrode plates, wherein the piston pump is connected to an input feed pipe and an outlet feed pipe.
