Envirogen has completed a comprehensive testing program on a variety of iron-based media including zero valent iron and chemically modified iron. After evaluating for physical characteristics, selenium absorption ability and rate of absorption, as well as impact of sulfate and chloride on the media, it became clear that the media differ greatly on all parameters tested. The extensive data gathered in our pilot facility will benefit clients in the proper selection of media, that will ultimately make a critical difference in compliance and system lifecycle costs for each specific customer’s application.
