Metsorb Arsenic Filter Media

MetSorb HMRG 16/60 is a patented titanium dioxide (TiO2) based granular adsorbent media used to remove arsenic III & V (trivalent and pentavalent, respectively), and a wide variety of heavy metals including Lead, Cadmium, Copper, Chromium+6, Selenium, and Zinc from drinking water. It is also frequently used to remove uranium.

• top-performing arsenic removal media
• removes both trivalent and pentavalent arsenic as well as a wide range of heavy metals
• spent media meets requirements for non-hazardous landfill disposal
• minimal backwash requirements reduces water waste
• will not "dump" arsenic upon media exhaustion
• does not require chemical regeneration
• low cost per gallon treated - long media life in most applications
• less affected by competing ions than competitive technologies
• made in the U.S.A.

Independent testing consistently ranks MetSorb as a leading media for the removal of arsenic. It has a higher capacity and a lower level of ion interference than competitive iron and alumina based media. MetSorb's extremely fast kinetics allow highly effective removal with contact times of only 1.5-3 minutes.

MetSorb systems are typically run in downflow configuration and does not require backwash in tanks smaller than 12" diameter.

Pre-filtration for iron, manganese, and sediment particulates can help protect media from fouling.

Treatment systems can be configured as single-tank systems or as multi-tank systems in parallel for higher flow rates or in series flow for applications with high influent arsenic concentrations (generally recommended where the arsenic levels exceed 60 ppb). An empty-bed contact time (EBCT) of 3 minutes is recommended for challenging water qualities.

MetSorb HMRG has been evaluated using both the EPA TCLP (CFR 40-RCRA Regs.) and California WET methods and has been found to be non-hazardous and safe for landfill disposal. Since each application differs, however, Graver Technologies and HomePlus Products recommend that exhausted MetSorb HMRG be evaluated following all federal, state, and local regulations regarding necessary approvals for landfill disposal.

We strongly recommend ongoing water testing to monitor for arsenic breakthrough and to assess media life and schedule for media replacement.
