Electrodeposition coating facility

An electrodeposition coating facility comprising:

• a degreasing process section, wherein an object to be coated is subjected to a degreasing process using a degreasing solution;
• a post-degreasing rinse section, wherein the object that has been processed in the degreasing process section is washed with wash water;
• a chemical conversion process section, wherein the object that has been washed in the post-degreasing rinse section is subjected to a chemical conversion process using a conversion solution;
• a post-chemical-conversion rinse section, wherein the object that has been processed in the chemical conversion process section is washed with wash water;
• a electrodeposition coating section, wherein the object that has been washed in the post-chemical-conversion rinse section is subjected to electrodeposition coating using an electrodeposition solution;
• a post-electrodeposition rinse section, wherein the object that has been subjected to electrodeposition coating in the electrodeposition coating section is washed with wash water;
• a filtration process apparatus;
• and
• a wash water recycling line,
• wherein the filtration process apparatus performs a filtration process on wash water after being used to wash the object in the post-electrodeposition rinse section so as to separate and remove solids from the wash water, and
• wherein the wash water recycling line directly feeds, to the post-chemical-conversion rinse section, the wash water after being subjected to the filtration process in the filtration process apparatus as wash water to be used to wash the object in the post-chemical-conversion rinse section.
