Abstract

Use of natural zeolites deposited at Tokaj mountain, Hungary, for ammonia removal from synthetic and municipal wastewaters was studied. The optimal ion exchange conditions found were as follows: Na-form clinoptilolite, 0.5-1.0 mm in particle size and about 5-7 BV h-1 loading rate. Using synthetic wastewater in the column of 9.5 cm i.d. × 92 cm, about 4.50 mg NH3-N g-1 clinoptilolite ammonia breakthrough capacity was achieved. For regeneration of the ion exchange bed, 10-20 BV of regenerant were necessary to remove the 98-99%, of ammonia with flow rate of a 5-7 BV h-1.
