The efficient utilization of solids in a rotating bed reactor has been proven to yield substantial savings on material costs compared to a fixed bed reactor, but the processing time is also an important factor. From this perspective, we tested which technology could deionize water to a target conductivity the quickest. The same amount of mixed bed deionization resin was used in a rotating bed reactor and a column (fixed bed reactor) of equal size (4 L). A total of 1,000 L of water was deionized each, using best-in-class standard protocols for both technologies.
The results show that the rotating bed reactor is significantly faster, reaching the refernce conductivity level of 0.15 µS/cm 3.7-times faster than the column. As a consequence, the rotating bed reactor poses a drastically more time-efficient technical solution for the removal of ions from water than fixed bed reactors. Additionally, if regeneration of the solid phase is an option, the RBR enables resource efficient regeneration with minimal waste creation. In other settings, the solid media might be delt with as solid waste as a whole.
What would a 3.7-fold increase in productivity mean for your process?
