Özet
Ammonia is an important nutrient in primary production, but high ammoniaconcentration is directly or indirectly toxic to many species of aquatic organisms.Ammonia and other toxic metabolites can be managed by adsorption and ionexchange. Zeolite is naturally occurring structured, aluminosilicate with highcation exchange and ion adsorption capacity. The purpose of this study was todetermine the effects of zeolite on the ammonium adsorption at different particlesizes (0.075 mm, 3-5 mm) and adsorbent dosages (5 g/l, 10 g/l, 15 g/l) fromaquatic solution. This research was conducted by trial groups with 3 repetitionsduring 330 min. Water temperature, pH, dissolved oxygen and ammonium valueswere measured during the trial period at regular intervals. Depending on therelevant literature, TAN (Total Ammonium Nitrogen) and adsorption efficiencywere also calculated. This study values showed a decrease of TAN concentrationin all the groups with increasing contact time. For different particle size andadsorbent dosage of zeolite, the best efficiency (44.1%) is determined at added 15g/l and 0.075 mm zeolite group (P˂0.05). Our results revealed that zeolite mightbe used for ammonia removal in aquaculture.
