Abstract

PURPOSE: To effectively dissolve deposited and adhered matter in a short time, by electrodialyzing the contaminated matter of on and in the membrane at a low acidic state by electrodialysis method and forcibly moving H+ into the inner part of membrane and moreover, putting the surface and inner part of membrane in low H+ concentration (pH) that is, in high acid concentration state.
