Biodegradation of Linear Alkyl Benzene Sulfonate by Sequencing Batch Reactor in Sanitary Wastewater
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 ...
متن کاملEvaluation of sequencing batch reactor performance for petrochemical wastewater treatment
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...
متن کاملBiodegradation of high concentrations of phenol by baker’s yeast in anaerobic sequencing batch reactor
Background: Phenol, as a pure substance, is used in many fields because of its disinfectant, germicidal, local anesthetic, and peptizing properties. Aqueous solutions of phenol are produced as waste in industries and discharged into the environment. Therefore, elevated concentrations of phenol may be found in air or water because of industrial discharge or the use of phenolic products. Method: ...

متن کاملBiodegradation of tannery wastewater using sequencing batch reactor--respirometric assessment.
This investigation proved that respirometry combined with sequencing batch reactor (SBR) could be an effective way for the removal of COD in tannery wastewater. Measurement of oxygen uptake rates (OUR) and corresponding COD uptake rates showed that a 12-h operating cycle was optimum for tannery wastewater. The removal of COD by degradation was stoichiometric with oxygen usage. A plot of OUR val...
