DESIGN OF AMMONIUM STRIPPING TOWER AND OPTIMIZATION OF AMMONIUM REMOVAL FROM LANDFİLL LEACHATE

Abstract

Landfill leachates are complex wastewater which has high pollution and their biological degradability is also difficult. Landfill leachate with high concentrations of contaminants must be pretreated. For this reason, the ammonium stripping process is an effective method for ammonium removal, especially for landfill leachate. With the ammonium stripping process, the ammonium and organic matter removal increases. This study aimed to investigate the applicability of the ammonium stripping process as remove ammonium (NH4+) and chemical oxygen demand (COD) from raw leachate. A new system has been designed which is called ammonium stripping tower. During this study, the ammonium stripping process was operated temperature (30-40-60oC), aeration rate (HH, HL, LL m3air/min), and hydraulic retention times (6-12-24-48 h). System performance was evaluated by ammonium, and COD parameters. The optimum conditions of the ammonium stripping process were determined at 600C temperature, HH(1m3air/min aeration rate), and hydraulic retention time (48h). The corresponding ammonium and COD removal efficiencies were about 88% and 79% respectively. The results of this study suggest that the use of an ammonium stripping process is an effective way to remove ammonium and COD concentration from raw landfill leachate.
