Abstract

The selective ion-exchange process derives its name from the use of zeolites that are selective for ammonia relative to calcium, magnesium and sodium. Clinoptilolite is the Zeolite currently favored for this use. The purpose of this research was to investigate the performance of clinoptilolite under different conditions of' pH, Bed depth and influent ammonium concentration. A 23 factorial design was made with two levels of these three variables. A bench scale laboratory set up was made to conduct these experiments.
