DI-tech UXA-NS Features and Benefits
Nitrate/Nitrite Selective The triethyl- ammonium functional group on this resin release sulfates before nitrates as the resin approaches exhaustion in service. This feature avoids the “dumping” phenomenon associated with standard SBA resins.
Regeneration and Pre-Treatment
DI-tech Activated Alumina can be field regenerated using first, a dilute solution of NaOH to strip the arsenic and fluoride. The media is then rinsed with feed water and the neutralized with a dilute solution of H2SO4 or HCl followed by a full rinse with clean water. Regeneration details are available from Systematix Co.
NSF-61 listed and suitable for potable feeds
Regenerates with salt ………..……. safe to use
