Sequencing batch reactor (SBR) and sequencing batch airlift reactor (SBAR) with the formation of aerobic granules
This research examined novel configuration of SBAR in lab-scale for industrial wastewater treatment. To evaluate COD removal efficiency and granules formation of the novel reactor (R1), SBAR system (R2) was operated under similar conditions during the experimental period. R1 and R2 with working volume of 3.6 and 4.5 L were used to cultivate aerobic granules. Both reactors were operated for 4 hr...
متن کاملAssessment of nitrogen and phosphorus removal in an intermittently aerated sequencing batch reactor (IASBR) and a sequencing batch reactor (SBR).
Biological nitrogen and phosphorus removal was investigated in an intermittently aerated sequencing batch reactor (IASBR) and a sequencing batch reactor (SBR). The removal efficiencies of ammonium-nitrogen (NH4(+)-N) were 100% in both reactors in steady operation state. The total nitrogen (TN) removal efficiencies were 90.4% in the IASBR and 79.3% in the SBR, while the total phosphorus (TP) rem...
متن کاملTreatment of Textile Industry Wastewater by Sequencing Batch Reactor (SBR), Modelling and Simulation of Biokinetic Parameters
In this study; variation of effluent BOD5’s (Se) with reaction time (tr) in Sequencing Batch Reactor (SBR) unit for textile industry wastewater treatment plant and effective parameters on this variation have been researched. Determination of appropriate reaction time (tr) is an important value for design and operation of activated sludge unit. An appropriate kinetic equation for Sequencing Batc...
متن کاملCharacteristics of MEG Removal from Industrial Wastewater by Sequencing Batch Reactor (SBR)
Background: MEG is extensively applied in the sour gas industry as a hydrate inhibitor. It is toxic in oral drinking and serious injury or death may result from swallowing of pure ethylene glycol and poses a potential hazard to the environment through impact soil. Glycols are harmful to aquatic life. There is little information about the digestion of MEG in the aerobic reactor. Therefore, t...
متن کاملMolecular analysis of bacterial community diversity in sequencing batch reactor (SBR) operating in autotrophic conditions.
In the present study the bacterial community structure in a sequencing batch reactor (SBR) operating in autotrophic conditions was determined in relation to temporal variations of NH4-N, NO2-N, NO3-N levels in the effluent. Bacterial richness and composition were determined by PCR-DGGE (Polymerase Chain Reaction - Denaturing Gradient Gel Electrophoresis) of 16S rRNA and amoA genes, and RISA (Ri...
