Ammonium removal from wastewaters using natural New Zealand zeolites

  title={Ammonium removal from wastewaters using natural New Zealand zeolites},
  author={Mai Lan Nguyen and C. C. TANNER},
Ammoniacal nitrogen (ammonia and ammonium) in agricultural wastewaters can promote eutrophication of receiving waters and be potentially toxic to fish and other aquatic life. Zeolites, which are hydrated aluminum-silicate minerals, have an affinity for ammonium ions (NH4"") and are, therefore, potentially useful in removing this contaminant from wastewaters. The major objectives of this study were to evaluate the capacity of two natural New Zealand zeolites (clinoptilolite and mordenite) to… CONTINUE READING
