LayneRT, manufactured by SolmeteXWater, is an NSF/ANSI 61 certified and approved arsenic removal media. This media is a hydrous iron oxide impregnated resin that efficiently and safely binds arsenic, and never needs backwashing. LayneRT was designed for use in our npXtra series of home treatment systems to effectively reduce arsenic well below the U.S. EPA’s MCL. Engineered in a lead/lag configuration to provide the best level of protection, the tanks are connected by a proprietary control head that provides valves for sampling the influent and effluent of both tanks. Once the lead column has exhausted, the tank with media can be sent back to SolmeteXWater for environmentally responsible disposal.
