ADSORBSIA GTO

ADSORBSIA™ GTO™ media is a granular titanium oxide with strong affinity for arsenic, lead, and other heavy metals. This unique media is designed for non-regenerative applications. The inherently high adsorptive capacity of Dow's titanium oxide based technology has been formulated into a mechanically stable granulation suitable for use in a broad range of potable water applications. When exhausted, it is removed from the vessel and replaced with new media. Spent media from arsenic loading tests have been shown to pass both the TCLP and CA WET extraction protocols. ADSORBSIA GTO media is NSF/ANSI Standard 61 certified without limitations.
