Abstract

The feasibility of hybrid systems for simultaneous removal of nitrate (NO₃^-) and ammonium ions (NH₄⁺) from livestock wastewater was examined in batch experiments. As a part of efforts to remove nitrate and ammonium simultaneously, Fe and adsorbents including coconut-based granular activated carbon (GAC), sepiolite and filtralite were used. Various parameters such as adsorbent dosages and temperature were studied. Removal of NO₃^- increased with increase in temperature. Maximum NO₃^- removal (85.3%) was observed for the Fe-filtralite hybrid system at 45C for a 24h reaction time. Increase in GAC and sepiolite dosages had significant (P<0.01) effect on the NH₄ ⁺ removal efficiency, which was primarily due to the net negative surface charge of the adsorbents. The efficiency of hybrid systems for the removal of NO₃^- was in the order of filtralite> sepiolite>GAC, and the order of the removal of NH₄⁺ was GAC>sepiolite>filtralite. The results of the present study suggest that the use of hybrid systems could be a promising innovative technology for achieving simultaneous removal of NO₃^- and NH ₄⁺ from livestock wastewater.
