Abstract

Nitrogen compounds are one of the several materials in the wastewaters and effluents that have harmful effects in water resources. In different experiences , ION EXCHANGE (IE) with ZEOLITEs were used for removal of Ammonia-nitrogen. The aim of this research was studying the application of Semnan's ZEOLITE for removal of AMMONIUM in both Batch and Continuous systems. The ZEOLITE Clinoptilolite was supplied by Semnan area mines. The ZEOLITE was ground and sieves based on U.S. standard mesh number 20 , 30 , 40 and then conditioned by AMMONIUM Sulfate and Sodium Chloride solutions respectively . The test results on conditioned samples in Batch system was showed that average ION EXCHANGE capacity for particles with 20 , 30 and 40 mesh were between 6.65 - 16 mg NH4+ /g ZEOLITE weight . Furthermore its selectivity for other cautions obtained the ranking of K, NH4, Na, Ca, Mg respectively. In Continuous system , total caution exchange and till breakthrough point capacity obtain 16.31 - 19.5 and 7.61 - 11.23 mg NH4+ / g ZEOLITE weight . The results indicated that high level of regeneration (95 - 98%) may be achieved with solution of NaCl. At present time, the most WASTEWATER TREATMENT plant in our country designed for removal of organic matter and AMMONIUM remain in effluent , and the use of ION EXCHANGE with Clinoptilolite can be led to economical remove of NH4 + from effluent .
