Finnish company Fortum has been providing ion exchange materials to Fukushima Daiichi since 2012. In their recent press release they explain what some of those filtration materials used in ALPS are.
A proprietary ion exchange material called Nures® includes three proprietary ion exchange materials
CsTreat® removes cesiums
SrTreat® removes strontium
CoTreat® removes cobalt

Fortum has received a significant additional order from the American EnergySolutions for ion exchange materials for purification of radioactive waters at the Fukushima Dai-ichi nuclear power plant in Japan. Fortum’s ion exchange materials have been used in the Advanced Liquid Processing System (ALPS) in the power plant area to purify radioactive waters for the past three years. EnergySolutions’s most recent order is one of Fortum’s largest deliveries of Nures® ion exchange materials to date.
“Fortum’s ion exchange materials effectively remove e.g. caesium and strontium from radioactive water. In addition to purification effectiveness, another advantage of the Fortum products is their cost efficiency: the amount of the product needed is very small compared to the volume of liquids to be purified,” says Fortum’s Heikki Andersson, Vice President, Power Solutions.
Fortum’s method significantly reduces the need for intermediate and final disposal repository space for radioactive liquids. Fortum has sold ion exchange materials for some 60 different applications around the world. Fortum has supplied ion exchange materials to Fukushima since spring 2012.

Nures® product and ion exchange materials
Fortum has over 20 years of experience in treating waste containing radioactive impurities with Nures® products. Fortum initially developed the product for use at its own Loviisa nuclear power plant. The Fortum-developed products are designed to e.g. remove caesium, strontium and cobalt especially from large volumes of liquids that are particularly difficult to treat and which typically are very difficult and expensive to purify. Nures® contains extremely selective ion exchange materials CsTreat®, SrTreat® and CoTreat® to absorb radioactivity. A very small amount of these materials are needed compared to the volume of the liquid to be purified. The purified water doesn’t contain any harmful substances and thus it can be released into a water system. Esko Tusa, who has developed and sold products at Fortum for decades, received the 2015 Finnish Engineering Award for his accomplishments. The award is granted by Tekniikan akateemiset TEK and Tekniska Föreningen i Finland TFiF.
