Abstract
A method for treating the surface of an object to be treated includes introducing a surface treatment fluid into a reaction vessel () capable of receiving an object, introducing-the surface treatment fluid into a separation vessel () after the object is subjected to surface treatment, and circulating the surface treatment fluid, from which a contaminant has already been removed, to the reaction vessel (). At the time of treatment on the surface of the object, a circulation passage for the surface treatment fluid including the reaction vessel () is communicated and the surface treatment fluid is constantly circulated through the circulation passage.
