The Radex floc products are unique formulations of specialty or selective ion exchange and adsorptive media. Ultra-fine functional particles are processed to achieve hydraulic perme- abilities far beyond those normally attainable with fine particles. In essence, they behave like much larger granular or bead particles. The Radex media are useful in a broad spectrum of applications. Radionuclide reduction in contaminated radwaste water sources is a prime area of application. Products such as Cs Floc and Co Floc, remove cesium and cobalt. Other selective Radex versions are available, as required.
