The application of MSBR in wastewater treatment including its principal base, operational instruction and technical feature are presented. As a newly developed modified SBR (Sequential Batch Reactor) MSBR has the advantages of both SBR and conventional activated active sludge processes. Both the primary and secondary sedimentation tanks can be omitted and continuous operation with full filling ...

A mathematical model was developed that can be used to describe an aerobic granular sludge reactor, fed with a defined influent, capable of simultaneously removing COD, nitrogen and phosphate in one sequencing batch reactor (SBR). The model described the experimental data from this complex system sufficiently. The effect of process parameters on the nutrient removal rates could therefore be rel...

The application of simultaneous adsorption and biodegradation processes in the same reactor is known to be effective in the removal of both biodegradable and non-biodegradable contaminants in various kinds of wastewater. The objective of this study is to evaluate the efficacy of the two processes under sequencing batch reactor (SBR) operation in treating copper and cadmium-containing synthetic ...

The inhibition effect of rapid variations pH in wastewater on activated sludge was investigated laboratory-scale sequencing batch reactors (SBR). toxic influence 6.5 and 8.5 examined. experiment with preferable to formation high FA concentration showed a low risk second step nitrification (conversion nitrites nitrates). However, the reactor at first-step ammonia nitrites) caused by FNA formatio...

According to previous research, it has been proved that wastewater treatment plants (WWTPs) can retain more than 90 % of the MPs contained in wastewater. However, a significant fraction removed WWTPs is retained sludge floc and this may lead an environmental issue since biosolids be used as fertilizers. The purpose research was evaluate how presence polyethylene (PE) could interfere with activa...

Aerobic granular sludge (AGS) is based on self-granulated flocs forming mobile biofilms with a gel-like consistence. Bacterial and structural dynamics from flocs to granules were followed in anaerobic-aerobic sequencing batch reactors (SBR) fed with synthetic wastewater, namely a bubble column (BC-SBR) operated under wash-out conditions for fast granulation, and two stirred-tank enrichments of ...
