Abstract

A fluid treatment device is disclosed. The fluid treatment device includes at least a first electrode (120) and a second electrode (120) in direct contact with the fluid. The fluid treatment device may include a control device (300) which adjusts a parameter of an alternating potential difference provided between the first electrode and the second electrode based on the indication of the conductivity between the first electrode and the second electrode.
