METALICAPT® sorbents composed from nano/micro-fibres, having more powerful pollutants removal properties compare to actual metal removal technologies.
AJELIS fibers have extremely high metal capture speed, selectivity, capacity and a decreased regeneration demand frequency which, is to a great extent, a function of their extremely large surface areas.
METALICAPT® sorbents allow to remove heavy metals (copper nickel, zinc, lead, chrome, cobalt…) as well as some toxic organic compounds. These sorbents can substitute the conventional ion exchange resins or istalled in complement to your tertiary treatment procedures.
Benefits of fibers compare to ion exchange/chelating resins :
- Greater metal absorption capacity and selectivity :
– selectivity for Cs and Sr over Na
– heavy metal removal
– rare earths/ heavy metals, heavy / light rare earths selective separation
– precious metal separation from cyanide solutions
- Extra-high capacity
- Tolerance to organics – it is not necessary to deploy additional scavenging resin systems or activated carbon precursors
- Same set-up as ion exchange resins – but resins can be changed for AJELIS fibres
- Lower bed-volume passage
- Smaller scale treatment plants are possible
- Absorption of low level metal concentrations (below the threshold of conventional resins)
- Regeneration with the use of around 10 times less acid compare to resins
- Regeneration speed is higher (compared to circa 10x longer with a traditional ion exchange resin)
- Enhanced efficiency gives significant performance gains and reduced operational and capital costs
- >100 regenerations possible, no chemical degeneration through regeneration

low consumption of toxic organic solvents compare to the liquid-liquid extraction processes,
about 10-time less regeneration cycles needed due to fiber high capacity,
réduction d’un facteur 10 du temps nécessaire à l’extraction des métaux,
- fibers are not powders : easy handling and transport of dangerous waste are guaranteed (rare earths are often associated with other radioactive elements such as thorium or uranium)
