Regeneration of zeolites used for ammonium removal from anaerobic groundwater

This research focuses on the chemical regeneration of zeolites which have been used to remove ammonium from anaerobic groundwater. The main goals hereby have been: - The determination of the effect of multiple regeneration on the ion -exchange capacity of the zeolites - The testing of the effectiveness of two types of regenerant: NaOH and NaCl - To see whether it is possible to reduce the amount of chemicals used for regeneration by reusing the regenerant.
