a bench scale aerobic sequencing batch reactor (sbr) was evaluated in terms of its potential to treat synthetic dairy wastewater. the 2-l plexiglass bioreactor was supplied with oxygen via a fine bubble air diffuser, fed with synthetic dairy wastewater under various operational conditions. to analyze the process, three significant independent variables — influent chemical oxygen demand (cod), m...

due to the population growth and human activities in the agricultural and industrial fields, healthy and sanitary water has become scarce. due to its high contamination load, environmental harms and water discharge standards, starch producing industry is regarded as one of the industries polluting water sources which its treatment and recovery remains important. in the present study, after fabr...

Sequencing batch reactor (SBR) technology has found many applications in industrial wastewater treatment in recent years. The aim of this study was to determine the optimal time for a cycle of the sequencing batch reactor (SBR) and evaluate the performance of a SBR for petrochemical wastewater treatment in that cycle time. The reactor was operated with a suspended biomass configuration under ae...

The sequencing batch reactor (SBR) is a specific fill and draw version of the conventional activated sludge (AS) process. In contrast to continuous flow systems, the sequencing of batch processes in the SBR is time rather space oriented; metabolic reaction and solid/liquid separation take place at different times in the same reactor. This study aims to investigate the performance and treatment ...

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...

Background: Various chemical, physical and biologic treatment methods are being used to remove nitrogen and phosphorus from wastewater. Sequencing batch reactor (SBR) is a modified activated sludge process that removes phosphorus and organic material from sanitary wastewater, biologically. Methods: This study was conducted in 2016.The performance of an aerobic-anaerobic SBR pilot device, locat...

Introduction: Detergents lead to many environmental problems. The main aim of this study was to evaluate sequencing batch reactor (SBR) efficiency on Linear alkyl benzene sulfonate (LAS) removal. Materials and Methods: In this experimental study, to investigate the removal efficiency of LAS, a SBR reactor was used. A roughly 12-hour operating cycle was chosen which included the discharge time ...

In this study, nitrous oxide (N(2)O) emission was compared between the operations of two different sequencing batch reactors, conventional sequencing batch reactor (CNVSBR) and simultaneous nitrification and denitrification sequencing batch reactor (SND-SBR), using synthetic wastewater. The CNV-SBR consisted of anoxic (denitrification) and aerobic phases, whereas the SND-SBR consisted of a micr...
