Abstract:
1. A fluid treatment device for treating a fluid passing from a first location to a second location, the fluid treatment device comprising: a first electrode positioned between the first location and the second location, the first electrode having a plurality of opening there through to permit the fluid to pass from a first side of the first electrode to a second side of the first electrode; a second electrode positioned between the first location and the second location, the second electrode having a plurality of opening there through to permit the fluid to pass from a first side of the second electrode to a second side of the second electrode; and a control device coupled to the first electrode and the second electrode to provide an alternating potential difference between the first electrode and the second electrode and to monitor a conductivity between the first electrode and the second electrode, wherein at least one characteristic of the alternating potential difference is adjusted by the control device based on an indication of the conductivity between the first electrode and the second electrode, a period of the alternating potential difference being at least about 3 kHz, wherein the at least one characteristic includes a peak voltage and a duty cycle and in response to an increase in the conductivity between the first electrode and the second electrode the control device first reduces the peak voltage until a threshold peak voltage is reached and subsequently reduces the duty cycle of the alternating potential difference.
