Abstract:
... BACKGROUND: An osmotic membrane bioreactor (OMBR) is a wastewater treatment technique that presents low energy requirements, low membrane fouling and high removal of nutrients and organic matter. However, reverse salt flux is the main disadvantage because it causes conductivity increase in the bioreactor. This study compares the performance of a sequencing batch reactor (SBR) and an OMBR in terms ...

Formation process and fouling characteristics of the dynamic membrane were studied in a modified self-forming dynamic membrane bioreactor (SF-DMBR) for recovering the organic matters in wastewater, and the performance of this SF-DMBR was investigated. Results indicated that 80% of the organic matters in wastewater could be quickly recovered under continuous operation. Furthermore, the evolutions o ...

... Antibiotic resistance genes (ARGs) are an emerging concern in wastewater treatment plants (WWTPs), as dissemination of ARGs can pose a serious risk to human health. Few studies, however, have quantified ARGs in membrane bioreactors (MBRs), although MBRs have been widely used for both municipal and industrial wastewater treatment. To reveal the capacity of MBRs for removal of ARGs and the response ...
