Is chlorine dioxide (ClO2) compatible with the FILMTECTM membrane as a sanitizing agent?

Sanitization with agents containing combined chlorine is generally not recommended. FILMTEC membranes have shown some compatibility with pure chlorine dioxide.  Chlorine dioxide that is generated on-site from chlorine and sodium chlorate, however, is always contaminated with free chlorine that attacks the membrane.  One should consider DBNPA as a safer and more effective sanitizing agent for non-potable applications.
