Overview of Each Technology
ROBE
• Vacuum operation mode i.e. lower
corrosion rate and better heattransfer.
• Ability to produce dry, free-flowing
granular powders.
RDA
• Low residence time i.e. low activity
inventory and consequently low
shielding requirements
• No incrustation due to the moving
blades. The moving blades limits
the ability to treat concentrates
containing abrasive products.
• Simple technology.
UGU
• High throughput.
• Simple technology.
• Low residence time and the
consequent advantages.
CD-1000
• Vacuum operation mode
transforming the waste into a
uniform granular form.
• Easy movement and placement of
the system due to the skid
mounted modular sections.
• Low operation costs because of
high reliability, reduced
maintenance and personnel
