Respirometric Activity of Activated Sludge in Sequencing Batch Reactor Depending on Substrate and Dissolved Oxygen Concentration
The effect of the food/microorganisms (F/M) ratio and dissolved oxygen (DO) concentration in sequencing batch reactors (SBRs) on the microbial activity has been examined. One of the SBRs was fed with synthetic wastewater containing inorganic carbon compounds (COD/N ratio 0.7 g COD/g N). To the other SBR, both inorganic and organic carbon was supplied leading to 6.9 g COD/g N. The F/M ratios in ...
متن کاملAerobic Sludge Granulation in a Full-Scale Sequencing Batch Reactor
Aerobic granulation of activated sludge was successfully achieved in a full-scale sequencing batch reactor (SBR) with 50,000 m(3) d(-1) for treating a town's wastewater. After operation for 337 days, in this full-scale SBR, aerobic granules with an average SVI30 of 47.1 mL g(-1), diameter of 0.5 mm, and settling velocity of 42 m h(-1) were obtained. Compared to an anaerobic/oxic plug flow (A/O)...
متن کاملSettling Properties of Activated Sludge from a Sequencing Batch Reactor (SBR)
The purpose of this work was to examine the settling properties of activated sludge from a sequencing batch reactor (SBR). The experiments were carried out in a bench-scale reactor, fed with wastewater from the University of Olsztyn treatment plant. Concentrations of the examined activated sludge varied between 2.5 and 6.0 kg SS m. Laboratory analyses of the sludge comprised: sludge concentrati...
متن کاملEffects of adsorbents and copper(II) on activated sludge microorganisms and sequencing batch reactor treatment process.
Wastewater treatment systems employing simultaneous adsorption and biodegradation processes have proven to be effective in treating toxic pollutants present in industrial wastewater. The objective of this study is to evaluate the effect of Cu(II) and the efficacy of the powdered activated carbon (PAC) and activated rice husk (ARH) in reducing the toxic effect of Cu(II) on the activated sludge m...
متن کاملSequencing Batch Reactor versus Continuous Flow Process for Pilot Plant Research on Activated Sludge
The objective of this article is to compare the advantages and disadvantages of the sequencing batch reactor (SBR) versus the more conventional continuous flow reactor (CFR) setup for pilot plant studies. The SBR process can offer many superior features for research applications. The control of operational conditions is more reliable, precise and versatile. Data collection by sampling and on-li...
