“…AQUASIM, which is a frequently used simulation program, was utilized for model calibration and evaluation based on experimental data. Model calibration was implemented by means of an iterative calibration protocol involving manual calibration of model components in each iteration step and fitting all the model outputs to real‐time data .…”

BACKGROUND: This study involved model evaluation of the acute impact of sulfamethoxazole on utilization of peptone mixture and acetate by fast growing microbial cultures under aerobic conditions. These substrates were selected to represent complex and readily biodegradable organic carbon sources, respectively. Acclimated biomass was obtained from two fill/draw reactors sustained at a sludge age of 2 days, one fed with peptone mixture and the other with acetate. Acute inhibition was tested in two parallel sets of batch reactors. Each reactor set was started with acclimated biomass seeding and pulse sulfamethoxazole dosing, including a control reactor without antibiotic addition.

“…A counter-diffusion system could be provided by the MABR in which oxygen transferred from the bottom of the biofilm, while organic carbon reverse transmits from the bulk liquid into the biofilm [7]. It was enabled the proper environment for SND processes [17]. However, the amount of nitrogen removed was still limited by the supply of carbon source to denitrification.…”

A novel microbial fuel cell (MFC) was developed to enhance simultaneous nitrification and denitrification (SND) by employing electrons from the anode. The cathode chamber of the reactor consisted of a membrane aerated biofilm reactor (MABR) which was made of an electroconductivity aerated membrane. The maximum power density of 4.20 ± 0.12 W m-3 was obtained at a current density of 4.10 ± 0.11 A m-2 (external resistance = 10). Compared with an open-circuit system, the removal rates of NH 4 +-N and TN were improved by 9.48 ± 0.33% and 19.80 ± 0.84%, respectively, which could be ascribed to the electrochemical denitrification. The anode (chemical oxygen demand, COD) and cathode (NO 3-) chambers reached the maximum coulombic efficiencies (CEs) of 40.67 ± 1.05% and 42.84 ± 1.14%, respectively. It suggested that the electroconductivity MABR has some advantages in controlling aeration intensity, thus improving SND and CEs. Overall, EAM-MFC could successfully generate electricity from wastewater whilst showing high capacity for removing nitrogen at a low COD/N ratio of 2.8 ± 0.07 g COD g-1 N.

“…Studies were carried out using an anaerobic-aerobic-anoxic-aerobic system for simultaneous removal of nitrogen and phosphorus, and some important control strategies were suggested so that the DPAO are not inhibited [43]. Another suggestion was to use anaerobicaerobic-anoxic process which showed successful simultaneous removal of nitrogen and phosphate [44]. A novel scheme using anaerobic co-digestate of waste activated sludge and organic fraction of municipal solid waste in SBR, that can be integrated into municipal anaerobic co-digestion plants for denitrifying biological phosphorus removal via nitrite.…”

Sequencing batch reactors (SBRs), due to its operational flexibility and excellent process control possibilities, are being extensively used for the treatment of wastewater which nowadays is fast becoming contaminated with newer and more complex pollutants. It is also possible to include different expanding array of configurations and various operational modifications to meet the effluent limits which are also continuously getting upgraded. This article provides basic description of SBR process along with its functional and physical variants that lead to improved the removal of nutrients and emerging contaminants. The significance of selectors and various recent advancements in the application of SBR has been discussed along with the possibilities held by SBR process in the treatment of wastewater of different origins and composition to produce effluent of reusable quality.
