Removal of nutrients from sewage effluent in stabilization ponds using natural zeolite

Jordanian natural zeolitic tuff samples were tested as a tertiary treatment on the effluent of wastewater stabilization ponds using laboratory scale column methods. The results of the column method showed that the zeolitic tuff had high efficiencies for ammonium and phosphate removal, and low efficiencies for nitrate elimination. The highest removal value for ammonium was 78.6% using raw zeolitic tuff of 0.5...0.25 mm size fraction, while the highest removal for phosphate was 30.05% using Ca-form zeolitic tuff of 0.5...0.25 mm grain size.
