Assessment of Anaerobic Baffled Reactor Upgrade by Integrated Electrocoagulation Process for Municipal Wastewater Treatment
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 ...
متن کاملTreatment of Low-strength Industrial Wastewater Using Anaerobic Baffled Reactor
The performance of an anaerobic baffled reactor at the pilot scale, with a 100-L volume and six compartments, that is used to treat low-strength industrial wastewater (671.5±49.9 mg COD/L, 350.1±36.8 mg BOD5/L and 443.8±60.7 mg SO4 -2/L) was studied. The reactor was started with a hydraulic retention time (HRT) of 25 h at 35 oC, which was gradually reduced to 3.33 h. The best reactor performanc...
متن کاملHybrid anaerobic baffled reactor for treatment of desizing wastewater
Polyvinyl alcohol-containing desizing wastewater discharged within final textile wastewater has a great impact to the environment due to its poor biodegradability. An improved lab-scale hybrid anaerobic baffled reactor was developed to treat desizing wastewater. The modification was achieved by increasing the height of hybrid anaerobic baffled reactor and application of proper effluent recycle ...
متن کاملPerformance of an Anaerobic Baffled Reactor (ABR) in treatment of cassava wastewater
The performance of an anaerobic baffled reactor (ABR) was evaluated in the treatment of cassava wastewater, a pollutant residue. An ABR divided in four equal volume compartments (total volume 4L) and operated at 35ºC was used in cassava wastewater treatment. Feed tank chemical oxygen demand (COD) was varied from 2000 to 7000 mg L(-1) and it was evaluated the most appropriated hydraulic retentio...
متن کاملBiodegradation of Hexamethylenetetramine in Anaerobic Baffled Reactor
Due to its structure, hexamethylenetetramine (HMT) is a slowly biodegradable substance, hydrolysing in acid environment to ammonium and formaldehyde. Formaldehyde is toxic under normal conditions for biological treatment processes. Following an adaptation, a formaldehyde concentration of 1000 mg·l may become biodegradable both in aerobic and anaerobic conditions. Acidic conditions for hydrolysi...
