Technical Library

The science behind the solidification.

Four decades of independent research, national-laboratory treatability studies, field case histories, and patented waste-treatment technology — the documented evidence behind AQUASET®, PETROSET®, WTZ® and Fluid Tech's isotope-specific media.

Fluid Tech's products have been evaluated by Sandia National Laboratories, Argonne, the Savannah River Site, INL and other DOE facilities, deployed on major decommissioning projects, and protected by a patent portfolio spanning radioactive-waste solidification, ion exchange, and isotope-specific separation. This library collects that record. Browse by category below, or filter by technology.

Research & Treatability Studies

Independent national-laboratory & DOE evaluations

Third-party studies documenting how Fluid Tech media perform on real low-level, mixed, and TRU waste streams — the strongest, most citable evidence in the library.
