Abstract
If incorporated in a cleaning system using persulfuric acid, the invention serves for continuous cleaning while increasing the persulfuric acid concentration adequately to ensure enhanced cleaning performance. The invention provides a feeding apparatus that feeds persulfuric acid to a cleaning apparatus. The cleaning system uses an electrolysis reactorthat regenerates the persulfuric acid solution by performing electrolytic reaction to produce persulfate ions from sulfate ions contained in the solution, and a circulation linethat circulates the persulfuric acid solution between the cleaning vesseland the electrolysis reactor. Configured as above, the invention can provides a feeding apparatus. The cleaning system comprises said configuration and a cleaning vesselthat cleans objectsusing a persulfuric acid solutionas cleaning fluid.
