Samsung patents fluid cleaner that uses electric current to detect when done
Samsung describes a method for cleaning liquids by passing an electric current through them between two electrodes. The system monitors the electrical flow to determine when the cleaning process is finished, then releases the purified fluid while keeping the current active.
In the filing’s own words
A method of purifying a fluid includes applying a direct current between a first electrode and a second electrode to electrostatically purify the fluid, monitoring a current density between the first electrode and the second electrode, determining whether purification of the fluid is completed based on a degree of decrease in the current density over a predetermined time period being less than a predetermined threshold and based on determining that purification is completed, discharging the fluid while maintaining application of the DC to the first electrode and the second electrode.
What exactly they claim (claim 1)
1. A method of purifying a fluid, the method comprising: applying a direct current between a first electrode and a second electrode to electrostatically purify the fluid; monitoring a current density between the first electrode and the second electrode; determining whether purification of the fluid is completed based on a degree of decrease in the current density over a predetermined time period being less than a predetermined threshold; and based on determining that purification is completed, discharging the fluid while maintaining application of the DC to the first electrode and the second electrode.
