The invention is related to a method and an installation for removal of metal cations contained in a liquid, in which said liquid is brought into contact at a temperature greater than or equal to 60\xb0 C. The first charge supply unit is activated for generating a first voltage coupled to a loop filter, and the second charge supply unit is activated for generating a second voltage coupled to the loop filter. The technique produces an isotropically expanding mist of particles. The method for monitoring and controlling the monitored device comprises the steps of: determining a malfunction state of the monitored device; and controlling a reapplication of power to the monitored device to reboot the monitored device based on the determined malfunction state of the monitored device. Each of the pieces may be composed of a titanium material.
