Our media have been used to treat contaminants in many types of projects: groundwater remediation, nuclear fuel pools and nuclear power plants.
Technology Proven Over Centuries
Based on ion exchange – a natural phenomenon that has been harnessed by scientists and engineers for over 150 years – Veolia Nuclear Solutions’ Ion Specific Media builds upon technologies and is proven to be effective for environmental remediation.
Our inorganic Ion Specific Media (ISM®) captures specific ions from contaminated water efficiently and economically. Ion exchange plays a crucial role in protecting the environment from nuclear waste, particularly ions found in contaminated water.
A Molecular Filter
The greatest threat to human health and the surrounding environment are ions and isotopes with long half-lives, such as cesium-137, strontium-90, iodine-129, and technetium-99. We capture these hazards with Veolia’s Ion Specific Media through an ion exchange process.
Ion exchange materials can capture ions based on both their size and charge. Imagine a chain-link fence: The wires form a hole in which a single golf ball is perched. If a tennis ball were to hit the fence, it would displace the golf ball and stick within the links. Similarly, ions such as cesium act as the tennis ball during the ion exchange process, where they displace sodium and are captured within the exchange material.
Flexible and Efficient
Veolia Nuclear Solutions offers several classes of Ion Specific Media: zeolite-based, titanosilicate-based, phosphate-based and fully synthetic specialty media for difficult projects.
Our media offers multiple advantages over alternative materials
Low sensitivity to pH and salt water
Excellent glass formers
ISM® are uniquely robust across a wide range of operating parameters and are compatible with existing nuclear power plant water purification and demineralization filtration systems. Specialty mobile systems allow ISM to be quickly deployed in remote or hazardous locations.
Our Ion Specific Media are available in three formats to accommodate the needs of any project:
Batch applications → Powder
Column applications → Granular
Specialty applications → Spherical
