Ammonia Removal from Tannery Wastewaters by Selective Ion Exchange on Slovak Clinoptilolite
The purpose of the work was to verify and demonstrate, on a pilot plant scale, the applicability of the Slovak clinoptilolite as a natural selective ion exchanger for the removal of ammonia from tannery wastewaters. During the pilot treatment experiments at an industrial wastewater treatment plant of the Shoe Manufacturing Industry Svit‐Otrokovice, about 260 m3 of wastewaters were treated. The regeneration process was carried out with 2% NaCl (pH = 9, NaOH) and the eluate was distributed into 3 fractions. Only the most concentrated ammonia fraction was stripped in the renovation step. The economic efficiency of the studied method was compared with the biological nitrification‐denitrification method.
