AMS, the pioneer of the in-situ stannous generation system, has significantly widened the application of this highly effective non-toxic metal to address a broad range of waterborne and airborne contaminants that threaten the health of people and their environment. SafeGuard™ H2O will enable the cost-effective treatment of drinking and industrial effluent that is contaminated with trace metals and capture airborne contaminants such as nitrogen oxides, hydrogen sulfide and sulfur dioxide.
