ABSTRACT:
The discharge of copper from isothiazolone biocides into industrial waste water streams is prevented by contacting the isothiazolone biocide as it is withdrawn from a point of use storage container with an ion exchange resin capable of removing copper from aqueous solutions. When the treated isothiazolone biocide is added to an industrial process water which will produce waste stream, potential copper contamination is virtually eliminated.
