Abstract

Laboratory experiments were carried out for removal of ammonium and phosphate ions from simulated wastewater by ion exchange and adsorption methods. Natural Hungarian zeolite containing about 56-58% clinoptilolite as ion exchanger and activated alumina as adsorbent were used. Depending on the influent NH//4** plus and PO//4**3** minus concentrations different ion exchange and adsorption capacities were achieved. Regeneration of the spent ion exchanger and adsorbent was accomplished by use of 10 g/dm**3 NaCl solution and 1 M NaOH solution, respectively. Based on the results of several exhaustion-regeneration cycles a pilot-plant scale study is suggested for successive removal of NH//4** plus and PO//4**3** minus ions after biological treatment of municipal wastewater.
