Patent ID: 8262890

Claim:
An electrodeposition painting system comprising: an electrodeposition bath containing an electrodeposition paint solution comprising paint and water, wherein the electrodeposition paint solution is in contact with an electrodeposition bath anode that charges the paint such that it electrocoats one or more parts submerged in the electrodeposition paint solution to form one or more electrocoated parts; a rinse tank that rinses the one or more electrocoated parts, wherein a rinse tank reservoir of the rinse tank is capable of fluid communication with the electrodeposition bath; a filter that filters the electrodeposition paint solution to separate filtered water from the paint; and an ionizer assembly comprising one or more electrodes in contact with the filtered water and a power supply connected to the one or more electrodes, wherein the power supply causes a plurality of electrode ions from the one or more electrodes to enter the filtered water to produce filtered water comprising electrode ions such that the filtered water comprising electrode ions flows into and sterilizes the electrodeposition paint solution.
