Recently, the U.S. Environmental ProtectionAgency mandated by law that all drinkingwater systems meet the new arsenicstandard of 10 parts per billion.

Our patented METSORB™ adsorbentproducts have been specifically engineer-ed to provide excellent Arsenic, Lead andother Heavy Metal contaminant removalfor the purification of drinking water,process water and other criticalpurification applications.

METSORB HMRG is a highlyeffective granular adsorbent that removesarsenic III & V, and a wide variety ofheavy metals including Lead, Cadmium,Copper, Chromium+6 , Selenium, andZinc from aqueous sources. METSORBHMRP is a powdered form of theadsorbent that is effective for lead andheavy metal removal in carbon block.METSORB utilizes a patented Titaniumcompound to adsorb both forms of arsenicas well as a wide range of contaminantsin water.

Metsorb maintains a higher capacityand a lower level of ion interference thancompetitive iron and alumina basedproducts.The media is long-lasting andupon exhaustion, has consistently testednon-hazardous for disposal classifi-cation.The media is NSF Standard 61approved, and has received regulatoryapproval from agencies across theUnited States and Canada.

Aqueous streams are common to manyindustrial processes. The selective removalof a broad range of contaminantsenables the process fluid to be reused toincrease operating efficiency andimprove finished product quality. Inaddition, more strictly enforcedenvironmental regulations are requiringindustry to lower contaminant levels ofdischarge streams.

Products from Graver Technologiesfilter particulate matter in the processstream and reduce trace levels ofcontaminants. Our prefilters and finalmembrane filters are used to produceultra pure DI water for semiconductorplants. Membrane products are used forclarification or concentration of highsolids in waste streams. Our ionexchange and adsorbent products areideal for heavy metals removal andrecovery. Graver’s industrial products aredesigned for applications where high dirtloading and flow rates make standardfilter cartridges ineffective.
