ÐBiological treatment of a piggery wastewater for organic carbon and nitrogen removal in a combined anaerobic±aerobic system was investigated using two laboratory-scale sequencing batch reactors. The cycle length was 24 h. In the anaerobic reactor, fed with raw wastewater and recycling from the aerobic reactor, denitri®cation followed by anaerobic digestion of organic carbon was observed. In th...

Introduction: Detergents lead to many environmental problems. The main aim of this study was to evaluate sequencing batch reactor (SBR) efficiency on Linear alkyl benzene sulfonate (LAS) removal. Materials and Methods: In this experimental study, to investigate the removal efficiency of LAS, a SBR reactor was used. A roughly 12-hour operating cycle was chosen which included the discharge time ...

In present study, effluent from anaerobic digestion of swine wastewater was treated by the simultaneous partial nitrification, anaerobic ammonium oxidation and denitrification (SNAD) process using a lab scale 5L sequencing batch reactor (SBR) under ambient temperature. The fluctuation of anaerobic digester liquor quality (COD, 387 ± 145 mg/L; TKN, 662 ± 190 mg/L; NH₄(+)-N, 519 ± 134 mg/L) and t...

Microbial treatment of bis(2-ethylhexyl)phthalate (BEHP) contaminated soil was evaluated in batch and sequencing batch reactors (SBR) using a mixed bacterial culture isolated from a BEHP-contaminated site. The BEHP-degrading mixed culture had three predominant component strains, Bre ibacterium iodinum, Rhodococcus luteus and Bacillus bre is. For soil slurry SBR studies, the hydraulic residence ...
