Nitrogen in the ammonia form can have deleterious effects including accelerated eu trophication of lakes, dissolved oxygen (do) depletion in receiving waters, and fish toxicity. Ammonia also reacts with chlorine used for disinfection in wastewater treatment to pro duce chlor amines. Chloramines are less effec tive disinfectants and are toxic to aquatic life in the receiving waters. Ion exchange has been demonstrated to be competitive with other methods of ammonia removal.1 However, the cost of chemical re generation of clinoptilolite remains high and represents more than 50 to 60% of the total process costs even with r?g?n?rant reuse.1 In an effort to find a more economical means
