RoCide DB20 is a concentrated, fast-acting, non-oxidizing liquid biocide for intermittent use that provides instant antimicrobial activity. It is based on a 20% solution of the active ingredient dibromo nitrilopropionamide (DBNPA). RoCide DB20 is certified by the U.S. Environmental Protection Agency (EPA) for use in reverse osmosis (RO) systems.
