Treatment of landfill leachate by anaerobic baffled reactor (ABR)

Anaerobic baffled reactor (ABR) is one of the widely used wastewater treatment systems in industrial and domestic applications. In this study, effect dilution rates (5%, %10, 20%, 50%) on landfill leachate (LFL) with regard to chemical oxygen demand (COD), color, nitrogen compounds, organic matter was investigated. The maximum removals were observed when rate 20% (v:v,1:5). COD, dissolved carbon (DOC), total (TN), nitrate (NO3-) ammonium (NH4+) removal efficiency approximately 81%, 61%, 15%, 17%, 1% 5%, respectively. results indicated that adverse effects contaminants are high it higher than 1:5 (v:v). study suggests presents a significant performance.
