US-based Honeywell’s wholly-owned subsidiary UOP, has announced that its adsorbents were used by Toshiba and Shaw, to clean about 100 million gallons of radiation contaminated water at the Japan’s Fukushima Daiichi nuclear power plant.

The crystalline material IONSIV Selective Media adsorbents are designed to selectively remove radioactive ions, particularly cesium and strontium, from liquids and have reduced cesium to below detectable levels.

UOP Catalysts, Adsorbents and Specialties business unit vice president and general manager Mike Millard said the company will continue to help removing radioactive contaminants from all water sources.

"Our products were chosen for their superior ability to remove large amounts of radioactive materials, including cesium from seawater, which is challenging," Millard added.

"UOP is proud of the contribution our IONSIV adsorbents have made toward reducing the radiation risk in Japan and helping the area recover from this devastating event."

Toshiba and Shaw Global Services used UOP’s IONSIV Selective Media adsorbents to treat the wastewater at the nuclear plant, which was radiation contaminated after the March 2011 earthquake and tsunami in the country.
