Refurbishment of Neutralization and Decontamination Station NDS – 6 in Stráž pod Ralskem

05/2017–10/2018

Client:
DIAMO NDS6
Designer:
Královopolská RIA, a.s.
Contractor:
Subterra a.s.

The project is located in the area of the former uranium mines in Stráž pod Ralskem. A complex of unique remediation systems was built to ensure the removal of a chemical contamination from the pumped solutions. The contaminants from the solutions can be extracted in three different ways. Uranium compounds are trapped on ion-inverter and separated by increasing the concentration of the solutions and subsequent alum crystallization or they are reprocessed and stored as insoluble sludge. The pumping of the residual solutions is controlled by mathematical models which evaluate the results of the geological monitoring. Solutions with the lowest concentration are processed by neutralization and decontamination station. We delivered sedimentation and filtration technology.
