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. ...

This present paper reports a study of the efficiency of an anaerobic Baffled Reactor (ABR) composed of three chambers working as the first stage of a biological treatment system for swine wastewater, over a period of 116 days. The average value of the volumetric organic loading rate (VOLR) was 17.8 kgCODtotal m d, the biological organic loading rates (BOLR) based on total and filtered COD influ...

In this study, hydrogen production from starch wastewater using anaerobic sludge immobilized on maghemite nanoparticles (γ-Fe2O3) was investigated. Two anaerobic baffled reactors (ABR-1 and ABR-2) were operated at organic loading rate (OLR) of 3.63±0.43 g-COD/L.d and hydraulic retention time (HRT) of 10 h. The ABR-1 was inoculated with 3.5 g-VSS/L preheated sludge at 90°C for 30 minutes. The se...

Pabrik Tahu Kumpai Kecil merupakan salah satu industri skala kecil di Kecamatan Sungai Raya, Kabupaten Kubu yang menghasilkan air limbah tahu dibuang ke badan tanpa diolah dahulu. Sampel diambil dengan cara komposit waktu. Debit diukur secara volumetrik menampung pada gelas takar sehingga diperoleh debit rata-rata harian untuk perencanaan sebesar 1,8 m3/hari. Hasil uji kualitas menunjukkan semu...

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...

In Egypt, there is a growing realization between experts and decision makers that low-cost anaerobic treatment technologies such as the Up-flow septic tank followed by anaerobic baffled reactor is a promising technology. It is characterized by its high organic removal efficiency, simplicity, low capital and maintenance costs. However, anaerobic treatment produces wastewater which is not complyi...
