In this study, it was aimed to determine the effects of zeolite and bentonite on the ammonium adsorption at different temperatures. In this research three trial groups with 3 repetitions were created for three different water temperatures (18±0.1°C, 24±0.0°C, 27±0.0°C). Experimental groups were prepared by adding NH4 + amount of 10.5 mg/l in 2 liters of water. After that, zeolite, zeolite+bentonite and bentonite were added into the bottles as 10 gram per liter. Water temperature, pH and TAN (Total Ammonium Nitrogen) values were determined during the trial period. At the end of trial TAN values at 27 °C were recorded as 10.103±0.11 mg/l, 9.227±0.13 mg/l and 7.933±0.17 mg/l in zeolite, zeolite+bentonite and bentonite groups, respectively. At the end of trial TAN values at 24 °C were recorded as 10.027±0.17 mg/l, 9.282±0.15 mg/l and 8.336±0.15 mg/l in zeolite, zeolite+bentonite and bentonite groups, respectively. At the end of trial TAN values at 18 °C were recorded as 9.012±0.28 mg/l, 7.702±0.14 mg/l and 6.594±0.14 mg/l in zeolite, zeolite+bentonite and bentonite groups, respectively. Maximum ammonium removal capacity, qe, was found to be 0.50 mg/g in the bentonite (18 °C). The TAN values determined at 18 °C were statistically more significant (p<0.05) than the TAN values obtained at 24 °C and 27 °C.
