The objective of this study was to assess the feasibility of the Sequencing Batch Reactor (SBR) system for implementation in Malaysia. Theoretical, field, laboratory investigations, and modelling simulations have been carried out. The results of the study indicated that the SBR system was robust, relatively cost-effective, and efficient under Malaysian conditions. However, the SBR system requir...

Anaerobic ammonium-oxidizing (Anammox) bacteria were enriched from sludge collected at a conventional activated sludge system treating domestic wastewater of Belo Horizonte(MG), Brazil, employing a sequencing batch reactor (SBR). After three months of cultivation, Anammox activity was detected in the system by the consumption of stoichiometric amounts of NO2 and NH4 +. Fluorescent in situ hybri...

background : the sequencing batch reactor (sbr) is one of the most widely used systems in sewage treatment because of the simplicity of the process, flexibility of operation in the removal of nutrients, and the ability to be used in different scales. the aim of this study was to evaluate the efficiency of the sbr in the removal of organic matter (nitrogen and phosphorus) from synthetic wastewat...

In this study biomass acclimation in a side stream partial nitrification sequencing batch reactor (SBR) was performed under optimum conditions (T 30ºC, SRT 9± 1 days and hydraulic retention time (HRT) 1.2 day). Excess sludge for solids retention time (SRT) regulation was added to another batch reactor (main stream) which performed under different conditions for partial nitrification evaluation ...

The benefits of deammonification to remove nitrogen from sidestreams, i.e., sludge dewatering liquors, in municipal wastewater treatment plants are well accepted. ammonia removal liquors originated thermal hydrolysis/anaerobic digestion (THP/AD) deemed challenging. Many different commercial technologies have been applied varying reactor design, biomass growth form and instrumentation control st...

The inhibitory effects of antibiotics (tetracycline, doxycycline, amoxicillin), an anti-inflammatory (ibuprofen) and an analgesic (paracetamol) on the via nitrite nitrogen and phosphorus removal processes were investigated. Biomass was collected from a sequencing batch reactor (SBR) and was spiked with fixed pharmaceutical concentrations (i.e. 50-500 mgL). Then, batch activity tests were conduc...

A sequencing batch reactor (SBR) inoculated with activated sludge and bioaugmented a dye-decolorizing yeast strain—Yarrowia lipolytica (HOMOGST27AB) was assembled to form yeast-bioaugmented aerobic granular (AGS). The AGS-SBR operated for the treatment of synthetic saline wastewater (12 g L−1) intermittently fed reactive textile dye (Navy Everzol ED) at 25, 15, 7.5 mg L−1. Dye degradation did n...

The goal of this study was to identify bacterial populations that assimilated methanol in a denitrifying sequencing batch reactor (SBR), using stable isotope probing (SIP) of (13)C labeled DNA and quantitatively track changes in these populations upon changing the electron donor from methanol to ethanol in the SBR feed. Based on SIP derived (13)C 16S rRNA gene clone libraries, dominant SBR meth...
