Membrane bioreactor

A three-stage submerged MBR was operated under a prolonged SRT condition—more than 800 days—to treat high strength industrial wastewater. Throughout the entire experiment, chemical and biological effects on sludge production and nitrification/denitrification were investigated. The trend of MLSS grow

The start-up of a pilot-scale membrane bioreactor equipped with submerged ultrafiltration membranes to treat municipal wastewater has been studied. Attention has been paid to determine membrane separation effects on biomass development in a reactor operated without inoculation. Moreover, the activat

The paper reports on the results of treatment of wastewater from the bottling of water and soft drinks with a membrane bioreactor (MBR) pilot plant. The existing conventional activated sludge process could not produce effluent suitable for discharge due to significant fluctuations of wastewater comp

The quality of effluent from urban wastewater destined for reuse was compared after treatment by a submerged membrane bioreactor (MBR) and a conventional activated sludge system followed by ultrafiltration (CAS-U). The study was carried out at pilot scale, using an MBR module equipped with hollow-fi

A novel osmotic membrane bioreactor (OsMBR) is presented. The system utilizes a submerged forward osmosis (FO) membrane module inside a bioreactor. Through osmosis, water is transported from the mixed liquor across a semi-permeable membrane, and into a draw solution (DS) with a higher osmotic pressu

The main objective of this work was to determine the impact of various backwash scenarios on fouling in a pilotscale submerged membrane bioreactor (MBR) aerobically treating domestic wastewater. A total of seven different backwash scenarios were tested. The degree of membrane fouling was determined

This study describes the experience received in operating an SM-SBR under different hydraulic retention times for the treatment of synthetic greywater. The pilot scale SM-SBR with a working volume of VR = 500 L is operated with hydraulic retention times of 33, 24 and 12 h, and a volumetric exchange

In the field of the wastewater treatment, membrane bioreactor technology continues to gain more and more interest thanks to high purification performance, low environmental impact, high possibility of treated water reuse. The more crucial factor in membrane bioreactor application is fouling tendency

Research on the treatment of two kinds model urban wastewater (W1, W2) with the contents of edible oil were carried out by activated sludge method in the membrane bioreactor. Biodegradation degree for readily and sparingly biodegradable compounds was determined on the basic of COD, BOD and TOC remov

In this study, the performance of sequencing batch reactor (SBR), aerobic membrane bioreactor (AMBR), anaerobic-oxic membrane bioreactor (AOMBR) and AOMBR/RO processes treating the synthetic textile dyeing wastewater (Reactive Black 5) was investigated and compared. After more than 2 year process op
