Membrane bioreactor technology represents the most rapidly growing membrane technology in the water sector. In recent years, MBR technologies have been playing a very important role in water and wastewater treatment. MBRs are used to treat a wide range of municipal and industrial wastewaters. MBR integrates membrane filtration with biological degradation system of waste products. It is defined ...

This review summarizes progresses in research on municipal wastewater treatment using anaerobic membrane bioreactors (AnMBR). At first, the AnMBR process options including membrane configuration and mean pore size or type are introduced. Next, many factors affect AnMBR performance in treating municipal wastewater, so this paper mainly focuses on the membrane characteristics, temperature, hydrau...

Several studies have noted that treated and untreated wastewaters are primary contributors of a variety of pathogenic microorganisms to the aquatic ecosystem. Conventional wastewater treatment may not be sufficient to achieve microbiologically safe effluent to be discharged into natural waters or reused, thus requiring wastewater effluents to be disinfected. In recent years, peracetic acid (PAA...

In this paper, a data-mining approach for modeling pumps in the wastewater preliminary treatment process is discussed. Datamining algorithms are utilized to develop pump performance models based on industrial data collected at a municipal wastewater processing plant. The performance of wastewater pumps is described by two parameters, pump energy consumption and water flow rate after the pumps. ...

the ultimate goal of this work was to recommend and install the necessary advanced wastewater treatment facilities to allow southern service company to continue discharging wastewater into st. bernard sewerage district no. 1 sanitary sewer system. as of june 14, 1976, these facilities were installed and fully operational. the resulting waste-water effluent was tested and found to be totally acc...

concurrent renewable energy production and wastewater treatment are two main reasons for using microbial fuel cells (mfcs). in this study, real wastewater was used for treating and power generation by air cathode microbial desalination cells (acmfc). the total duration of voltage generation by acmfc was about 151.9 ±23.2 h. the maximum voltage produced from municipal wastewater treatment was 27...

Municipal wastewater treatment plants consume much energy and manpower, are expensive to run, and generate sludge and treated wastewater whilst removing pollutants through specific treatment regimes. The sustainable development of the wastewater treatment industry is therefore challenging, and a comprehensive evaluation method is needed for assessing the sustainability of different wastewater t...

background: the purpose of this study was to investigate the efficiency of flat sheet membrane bioreactor (fs-mbr) in bod 5 and cod removal of isfahan south municipal wastewater treatment plant. methods: in this study a submerged fs-mbr, with 140 liters volume was fed using microfiltration membrane (mf) during 109 days and hydraulic retention time of 20 hours. findings: the mbr application in m...

There are many chemical constituents that enter the municipal waste stream that are of potential concern for human health. These substances include organic chemicals, inorganic trace elements (such as cadmium and lead), and nitrogen. Conventional agricultural practices, such as the use of commercial fertilizers, also have the potential to introduce additional chemical constituents to soil. Howe...

Biochemical processes by chemoautotrophs such as nitrifiers and sulfide and iron oxidizers are used extensively in wastewater treatment. The research described in this dissertation involved the study of two selected biological processes utilized in wastewater treatment mediated by chemoautotrophic bacteria: nitrification (biological removal of ammonia and nitrogen) and hydrogen sulfide (H2S) re...
