Abstract: PROBLEM TO BE SOLVED: To provide a feed back control system in which a water control system or the like are integrated, and which is usable for the removal of coatings from various works. SOLUTION: The coating removal system 10 has a stripping tank 12 in which an electrolytic solution bath stripping solution for removing a coating of at least one work 33 dipped into an electrolytic solution bath is stored, and further, an absolute potential is controlled in the at least one work 33 to a reference electrode dipped into the electrolytic solution bath. The system has a cleaning solution tank in which a cleaning solution for cleaning the work 33 after the completion of the removal of the coating from the work 33 is stored. The system has a distillation unit for purifying the electrolytic solution, and returning the electrolytic solution to the stripping tank as a purified form.

Abstract: A feedback controlled stripping system comprises a stripping tank 12 containing an electrolyte bath stripping solution for removing a coating from at least one workpiece immersed in the stripping solution while a controlled absolute electrical potential is maintained on the at least one workpiece with respect to a reference electrode also immersed in the stripping solution, a rinse tank 14 for rinsing the workpiece(s) after removal of the workpiece(s) from the stripping tank, and a distillation unit 16 for receiving electrolyte containing dissolved metals from the stripping tank, for purifying the electrolyte received from the stripping tank, and for returning the purified electrolyte to the stripping tank. In a preferred embodiment, the stripping tank 12, the rinse tank 14, and the distillation unit are mounted to a skid 18. The system further includes a control module.

Abstract: The present invention relates to a feedback controlled stripping system with integrated water management and acid recycling system. The system comprises a stripping tank containing an electrolyte bath stripping solution for removing a coating from at least one workpiece immersed in the stripping solution while a controlled absolute electrical potential is maintained on the at least one workpiece with respect to a reference electrode also immersed in the stripping solution, a rinse tank for rinsing the workpiece(s) after removal of the workpiece(s) from the stripping tank, and a distillation unit for receiving electrolyte containing dissolved metals from the stripping tank, for purifying the electrolyte received from the stripping tank, and for returning the purified electrolyte to the stripping tank. In a preferred embodiment, the stripping tank, the rinse tank, and the distillation unit are mounted to a skid. The system further includes a control module. A process for using the system to remove a coating from a workpiece is also described.
