Abstract: A ballast water treatment apparatus and a ballast water treatment system having a ballast water treatment apparatus are provided. The ballast water treatment apparatus includes a ballast water transport line configured to transport ballast water between a first location and a second location, the transported ballast water being passed through at least one injector, and a plasma generation device configured to be fed with a feed gas optionally comprising oxygen, and configured to generate a feed gas plasma by a streamer type discharge in a discharge area to provide a treated gas at a treated-gas outlet. The injector includes a liquid passage having an area constructed such as to increase a velocity of the passed-through water in a region of increased velocity, and an injector gas inlet provided in the region of increased velocity. The treated-gas outlet is in gaseous connection with the injector gas inlet.

Abstract: A pulse generator and a method for generating pulses are provided. The pulse generator includes at least one first transmission line with a first and a second end; at least one second transmission line with a first and a second end; a voltage source; a switching unit; and a charge control device. The charge control device is adapted to connect an output of the voltage source to the first end of the at least one first transmission line. A first switch S1 in the switching unit is adapted to connect or disconnect the second end of the at least one first transmission line to the first end of the at least one second transmission line for predetermined time spans. A second switch S2 in the switching unit is adapted to connect or disconnect the first end of the at least one second transmission line to a fixed potential. The opening or closing states of S1 and S2 in the switching unit are mutually exclusive. A second end of the at least one second transmission line is adapted to be connected to a load. The switching unit is further adapted to operate the first switch, S1, and the second switch, S2, in a predetermined order to alter a pre-charging state of the first transmission line.

Abstract: A Dielectric Barrier Discharge system controller for controlling a fluid treatment by a Dielectric Barrier Discharge system is provided. Therein, the strength of an effect caused by a discharge created by the Dielectric Barrier Discharge system is monitored, and the generation of high-voltage pulses by the high-voltage pulse generator is controlled. The controlling of the generation of the high-voltage pulses is adapted based on the received sensor data.
