Method and system for treating fluids by producing corona discharges in a fluid volume

The invention relates to a method for treating fluids (5) by producing corona discharges (12) in the fluid volume (6). According to said method, high-voltage pulses (8) are applied to an electrode arrangement (2) present in the fluid volume (6). Pulse rise times of the high-voltage pulses (8) are in the range of 1 to 40 nanoseconds and pulse duration of the high-voltage pulses (8) is in the range of 50 to 400 nanoseconds.
