Removal of Ammonium Nitrogen from the DAF-Pretreated Poultry Slaughterhouse Wastewater by Lemna minor

In this study, ammonium, COD, color and turbidity removal with using Lemna minor (duckweed) was searched in Poultry Slaughterhouse (PS) wastewaters. Reason of Poultry Slaughterhouse Wastewaters (PSW) contains high concentration of organic compounds, ammonia and fats. Wastewater was taken from effluent of Dissolved Air Flotation (DAF) unit, then using MAP process, upper phase was given to reactor which Lemna minor was being. COD, ammonia, color, turbidity parameters were analyzed after hydraulic retention time of 7 days. The result of the study showed that Lemna minor is effective in treatment of poultry slaughterhouse wastewaters. In this study especially ammonia removal was investigated. At the same time COD, color and turbidity removal were researched. In this study, ammonia removal efficient was around % 30.08 ± 4.67, Lemna minor was effective in COD, color and turbidity removal as 26.58 ± 8.35; 35.06 ± 15:20; and 51.07 ± 18.77 respectively removal.
