ResinTech, Inc. a manufacturer/supplier of ion exchange resins, activated carbon, and specialty media to the water and wastewater marketplace, has received the Water Quality Association’s 1 Gold Seal of approval for its chromate selective resin, ResinTech SIR-700. ResinTech SIR-700 now meets “NSF/ANSI-61: Drinking Water System Components - Health Effects” for use in all potable water applications.

SIR-700 has been used successfully for years at several Superfund sites to remove hexavalent chromium 2 from groundwater, in one case offering projected savings to the federal government of up to $20 million. The unique chemical structure of ResinTech SIR-700 provides tremendous throughput capacity with the ability to load more than 7 pounds of chrome per cubic foot of media under ideal conditions.

“We are all proud to supply a product that provides substantial health benefits,” said Michael Gottlieb, ResinTech’s president.
