MetSorb HMRP adsorbent is a free-flowing powder designed for incorporation into pressed or extruded carbon blocks. The addition of Gravers MetSorb HMRP at relatively low levels to a carbon block design is very effective for the reduction of lead, and at higher HMRP usage levels effective for reduction of arsenic, to meet the requirements of NSF Standard 42. MetSorb HMRP utilizes a patented material to adsorb not only cationic lead species, but also both forms of Arsenic: Arsenic III and Arsenic V, present as (neutral) arsenite and (anionic) arsenate respectively. MetSorb HMRP will also reduce a wide range of other metal contaminants commonly present in drinking water or process water, and is effective in polishing low levels of metal contaminants from industrial waste streams.
Recommended MetSorb HMRP Use
As a fine powder, the addition of MetSorb HMRP is recommended as a component of pressed or extruded carbon blocks, where heavy metal reduction is desired. In blending HMRP with carbon and poly binder components, one must assure that both the starting mechanical blend and the unfinished block produced appear homogeneous. The following guidance is provided as a starting point. The performance of each specific design should be evaluated as to reduction for the specific contaminant in question using industry -standard methodologies by qualified laboratories.
