    Ammonia removal from Sirofloc treated sewage using natural zeolite from Australia
    Cooney, Emma Louise ( 1996)
    A high-rate process for the removal of ammonia from sewage was investigated. Of the existing high-rate processes, ion-exchange with an ammonium-selective zeolite has shown considerable advantages. The recent commercial mining of a natural Australian zeolite, clinoptilolite, encouraged the investigation of its application to wastewater treatment for ammonia removal. The applicability of the mineral, for continuous ammonia removal from sewage, depends on its chemical and physical properties. For Australian zeolite, these factors, and thus the potential usefulness of this mineral for wastewater treatment, were largely unknown prior to this study. The study endeavoured to determine the most viable way in which to use Australian natural zeolite in this process, with the most critical part being the economical regeneration of the zeolite.
