Electrodeposition painting systems and methods for electrode sterilizing in electrodeposition painting systems

A method for electrode sterilizing in an electrodeposition painting system, the method comprising:

• electrocoating one or more parts in an electrodeposition paint solution to form one or more electrocoated parts, wherein the electrodeposition paint solution comprises water and paint;
• filtering out filtered water from the paint of the electrodeposition paint solution;
• passing the filtered water through an ionizer assembly and adding a plurality of electrode ions to the filtered water to form filtered water comprising electrode ions;
• rinsing the one or more electrocoated parts with the filtered water comprising electrode ions in a rinse tank;
• and
• collecting the filtered water comprising electrode ions in a rinse tank reservoir, the filtered water comprising electrode ions flowing into and sterilizing the electrodeposition paint solution.

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 filtering water circuit in fluid communication with the electrodeposition bath configured to filter the paint from the water to provide filtered water;
• and
• a sterilizing circuit that receives filtered water from the rinse tank, the sterilizing circuit including an ionizer assembly that introduces electrode ions to the filtered water.
