This work investigated the roles of sludge micropowder addition in microbial structure and partial nitrification denitrification (PND) an extended filamentous aerobic granular sludge-sequencing batch reactor (AGS-SBR) using high-ammonia wastewater. Type 1683 Acinetobacter with a high percentage became dominant filaments, remarkably shifted remained at low level, acting as framework for AGS reco...

Industrial wastewater discharges often contain high levels of organic matter and nutrients, which can lead to eutrophication constitute a serious hazard receiving waters aquatic life. The purpose this study was examine the efficacy using sequencing batch reactor (SBR) treat high-strength for removal both chemical oxygen demand (COD) nutrients (nitrogen phosphorus). At constant COD concentration...

background: the entrance of toxic compounds into wastewater treatment plants (wwtps) can induce disorder in their biological units. therefore, it is necessary to determine the sources of toxic wastewaters. in this study, the toxicity of the wastewater of 3 metal plating industries was assessed using sequencing batch reactor (sbr) bacteria. methods: to obtain the 1-1000 ml/l concentrations, the ...

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 ...

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...

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 ...
