Background & objectives: Anaerobic baffled reactor (ABR) is one of the low cost wastewater treatment systems compared to the aerobic method. Hoverer it should be studied and developed to overcome its limitations such as insufficient nutrient removal. The aim of this study was to evaluate the efficiency of the 5 sectional ABR pilot and improve it with integrated electric coagulation process for ...

The increasing need for wastewater reuse resulted in this study to investigate the effects of effluent from an anaerobic baffled reactor (ABR) on some chemical properties of three contrasting soils after effluent leaching and the implications for peri-urban agriculture. Soil columns were leached with ABR effluent or distilled water using 16 pore volumes after which the columns were sectioned in...

Treatment of starch wastewater was investigated in a 30 l capacity pilot scale anaerobic baffled reactor (ABR) under mesophillic conditions. The reactor was operated at different hydraulic retention times (HRTs) of 72; 48 and 24 h. Corresponding organic loading rates (OLRs) were 8.7; 7.6 and 22 kg COD/m 3 . d. The results showed that COD and BOD5 removals exceeded 40 and 50% respectively at OLR...

Acidic anaerobic digestion attracted much attention and interest due to its significant advantage in wastewater treatment. In the present study, methanogenic fermentation was successfully operated under acidic condition during treating containing oxytetracycline (OTC) a scale up baffled reactor (ABR). After start-up process, pH value first compartment 4.60 with high activity of methanogenesis. ...

The one-stage partial nitritation and anammox process with the hydroxyapatite (HAP)-based syntrophic granules was studied for ammonium nitrogen removal from effluents of a self-agitated anaerobic baffled reactor treating fish processing wastewater. When in influent 1140 mg N·L-1, high rate efficiency 1.51 ± 0.10 kg N·m−3·d-1 88.2% were obtained, respectively. Anammox bacteria Candidatus Kueneni...

With the increasing deterioration of world water resources, configuring a technical and economic viable wastewater treatment and recycle technology to satisfying the increasing complexity of wastewater and stringent environmental regulation has been a great challenge over the past decades. Developing reliable technologies for wastewater treatment is of urgent importance. In recent years, anaero...
