Metsorb® HMRG (Heavy Metal Removal Granules)
Highly Effective, Low-Cost Adsorbent for Reduction of Arsenic III & V
and a Wide Variety of Heavy Metals

MetSorb® HMRG and HMRP adsorbents utilize a patented material to adsorb both forms of arsenic as well as a wide range of contaminants in water. Empty bed contact times as low as 10 seconds achieve high removal efficiencies. The material affords a higher capacity and a lower level of ion interference than competitive iron and alumina based products.

MetSorb® HMRG media’s adsorptive capacity is 7-12 grams of arsenic per kilogram of HMRG adsorbent in drinking water applications with a pH range of 6.5-8.5. Much higher adsorptive capacities have been measured, up to 400 g/kg, in industrial treatment applications.

Adsorbent Product Features/Benefits

» Removal of heavy metals to meet drinking water standards

Comparison of HMRG adsorbent with
iron-based adsorbent.

Treatment capacity as a function of tank size.

Testing was done under the conditions specified by the NSF Standard 53 for Arsenic. Results at a pH of 6.5 and a pH of 8.5 are shown in the graph above.

Adsorption isotherms for lead between pH 5 and 7
are nearly identical.

The above graph shows the adsorption isotherm for Arsenic V at pH 8.5.
