Radiant-20 is a non-oxidising, non-ionic antimicrobial reverse osmosis biocide for use in membranes and pre-treatment plant. It has a broad spectrum of activity. Application on a routine basis will prevent the growth of biofilms on membrane surfaces, filter media and pipe work. Radiant-20 may also be used as a preservative for certain types of membranes such as thin film composite and other polyamide-type membranes.
