Performance Upgrading Evaluation of the Anaerobic Baffled Reactor by Integrating Aerobic Media Filter for Municipal Wastewater Treatment

Background & Aims of the Study: Anaerobic baffled reactor (ABR) is one low-cost wastewater treatment systems; however, it has some limitations, such as insufficient standard nutrient outflow. Accordingly, should be studied and developed. This research aims to determine efficiency a five-sectional pilot upgrade with an integrated aerated media filter in (integrated reactor) for municipal treatment. Materials Methods: study was performed on laboratory scale field conditions Khoy City plant. The ABR operated 270 days hydraulic retention time (HRT) 48, 36, 24, 18 hours, respectively. Integrated anaerobic (IABR) 35 24 hours HRT, i.e., aeration 5 hours. reactors were fed line from inflowing A 24-hour combined sampling 224 times inflow outflow system, volatile suspended solids, total kjeldahl nitrogen (TKN), phosphorus (TP), biochemical oxygen demand (BOD), chemical (COD), Total Suspended Solids (TSS) parameters measured compared effluent disposal standard. Results: launch lasted 105 days, its helpful operation 200 days. In 48 removed 79% 91% COD, 9% 20% TKN, 19% 30% phosphorus, 89% 94% TSS. IABR reached terms TSS, BOD, under increased COD removal by 6% HRT same conditions. Conclusion: By integrating final aerobic while reducing required 50%, achieving standards ABR. Therefore, this system can used treat wastewater.
