Yes, DuPont AmberLite HPR550 OH can be regenerated for extended use. In industrial settings, the resin is typically regenerated using caustic (sodium hydroxide) to restore its anionic (OH-) form. This regeneration process allows the resin to continue functioning effectively after repeated cycles of ion exchange, reducing the need for frequent replacements and contributing to its long operational life, which can exceed five years with proper maintenance and regeneration protocols.
