Biodegradation 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...
متن کاملTreatment of a textile dye in the anaerobic baffled reactor
Synthetic organic colourants, the majority of which are recalcitrant in nature, are used in many different manufacturing processes. The dyes are released into the environment in industrial effluents and are highly visible even at low concentrations (< 1 mg/l). Decolorisation of the dye CI Reactive Red 141 was investigated in a laboratory-scale anaerobic baffled reactor (ABR). The results of the...
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 کاملPerformance of Anaerobic Baffled Reactor for Biodegradation of Phenol
(Received: June 5, 2011; Accepted: July 29, 2011) Abstract: Effect of increase in phenol concentration on performance of anaerobic baffled reactor in terms of chemical oxygen demand (COD), phenol and COD removal efficiency and biogas productions was investigated. Furthermore, stability of the reactor with respect to the chemical shock load was monitored. The anaerobic baffled reactor was contin...
متن کاملSlaughterhouse wastewater treatment by combined anaerobic baffled reactor and anaerobic filter: study of OLR and HRT optimization in ABR/AF reactors
Background: Slaughterhouse wastewater (SWW) is hardly treated due to the large amount of organic matter, nutrients and suspended solids. These materials are naturally decomposed through biological processes, and then environmental pollution, transmission of pathogens and problems become smelled. Conventional purification methods require high investment costs, high energy consumption and expert ...
