Method and System for Treating Fluids by Producing Corona Discharges in a Fluid Volume

Auflistung Beschreibung

The invention pertains to a method for treating fluids by generating corona discharges within the fluid volume. This is achieved by applying high-voltage pulses to an electrode arrangement submerged in the fluid. The pulses have rise times ranging from 1 to 40 nanoseconds and durations between 50 to 400 nanoseconds.
